+= Active Record -- Object-relational mapping put on rails
+
+Active Record connects classes to relational database tables to establish an
+almost zero-configuration persistence layer for applications. The library
+provides a base class that, when subclassed, sets up a mapping between the new
+class and an existing table in the database. In the context of an application,
+these classes are commonly referred to as *models*. Models can also be
+connected to other models; this is done by defining *associations*.
+
+Active Record relies heavily on naming in that it uses class and association
+names to establish mappings between respective database tables and foreign key
+columns. Although these mappings can be defined explicitly, it's recommended
+to follow naming conventions, especially when getting started with the
+library.
+
+A short rundown of some of the major features:
+
+* Automated mapping between classes and tables, attributes and columns.
+
+   class Product < ActiveRecord::Base
+   end
+
+   The Product class is automatically mapped to the table named "products",
+   which might look like this:
+
+   CREATE TABLE products (
+     id int(11) NOT NULL auto_increment,
+     name varchar(255),
+     PRIMARY KEY  (id)
+   );
+
+   This would also define the following accessors: `Product#name` and
+   `Product#name=(new_name)`
+
+  {Learn more}[link:classes/ActiveRecord/Base.html]
+
+
+* Associations between objects defined by simple class methods.
+
+   class Firm < ActiveRecord::Base
+     has_many   :clients
+     has_one    :account
+     belongs_to :conglomerate
+   end
+
+  {Learn more}[link:classes/ActiveRecord/Associations/ClassMethods.html]
+
+
+* Aggregations of value objects.
+
+   class Account < ActiveRecord::Base
+     composed_of :balance, :class_name => "Money",
+                 :mapping => %w(balance amount)
+     composed_of :address,
+                 :mapping => [%w(address_street street), %w(address_city city)]
+   end
+
+  {Learn more}[link:classes/ActiveRecord/Aggregations/ClassMethods.html]
+
+
+* Validation rules that can differ for new or existing objects.
+
+    class Account < ActiveRecord::Base
+      validates_presence_of     :subdomain, :name, :email_address, :password
+      validates_uniqueness_of   :subdomain
+      validates_acceptance_of   :terms_of_service, :on => :create
+      validates_confirmation_of :password, :email_address, :on => :create
+    end
+
+  {Learn more}[link:classes/ActiveRecord/Validations.html]
+
+
+* Callbacks available for the entire life cycle (instantiation, saving, destroying, validating, etc.).
+
+   class Person < ActiveRecord::Base
+     before_destroy :invalidate_payment_plan
+     # the `invalidate_payment_plan` method gets called just before Person#destroy
+   end
+
+  {Learn more}[link:classes/ActiveRecord/Callbacks.html]
+
+
+* Observers that react to changes in a model.
+
+   class CommentObserver < ActiveRecord::Observer
+     def after_create(comment) # is called just after Comment#save
+       CommentMailer.new_comment_email("david@loudthinking.com", comment).deliver
+     end
+   end
+
+  {Learn more}[link:classes/ActiveRecord/Observer.html]
+
+
+* Inheritance hierarchies.
+
+   class Company < ActiveRecord::Base; end
+   class Firm < Company; end
+   class Client < Company; end
+   class PriorityClient < Client; end
+
+  {Learn more}[link:classes/ActiveRecord/Base.html]
+
+
+* Transactions.
+
+    # Database transaction
+    Account.transaction do
+      david.withdrawal(100)
+      mary.deposit(100)
+    end
+
+  {Learn more}[link:classes/ActiveRecord/Transactions/ClassMethods.html]
+
+
+* Reflections on columns, associations, and aggregations.
+
+    reflection = Firm.reflect_on_association(:clients)
+    reflection.klass # => Client (class)
+    Firm.columns # Returns an array of column descriptors for the firms table
+
+  {Learn more}[link:classes/ActiveRecord/Reflection/ClassMethods.html]
+
+
+* Database abstraction through simple adapters.
+
+    # connect to SQLite3
+    ActiveRecord::Base.establish_connection(:adapter => "sqlite3", :database => "dbfile.sqlite3")
+
+    # connect to MySQL with authentication
+    ActiveRecord::Base.establish_connection(
+      :adapter  => "mysql2",
+      :host     => "localhost",
+      :username => "me",
+      :password => "secret",
+      :database => "activerecord"
+    )
+
+  {Learn more}[link:classes/ActiveRecord/Base.html] and read about the built-in support for
+  MySQL[link:classes/ActiveRecord/ConnectionAdapters/MysqlAdapter.html],
+  PostgreSQL[link:classes/ActiveRecord/ConnectionAdapters/PostgreSQLAdapter.html], and
+  SQLite3[link:classes/ActiveRecord/ConnectionAdapters/SQLite3Adapter.html].
+
+
+* Logging support for Log4r[http://log4r.sourceforge.net] and Logger[http://www.ruby-doc.org/stdlib/libdoc/logger/rdoc].
+
+    ActiveRecord::Base.logger = Logger.new(STDOUT)
+    ActiveRecord::Base.logger = Log4r::Logger.new("Application Log")
+
+
+* Database agnostic schema management with Migrations.
+
+    class AddSystemSettings < ActiveRecord::Migration
+      def up
+        create_table :system_settings do |t|
+          t.string  :name
+          t.string  :label
+          t.text    :value
+          t.string  :type
+          t.integer :position
+        end
+
+        SystemSetting.create :name => "notice", :label => "Use notice?", :value => 1
+      end

+      def down
+        drop_table :system_settings

+
+
+== Philosophy
+
+Active Record is an implementation of the object-relational mapping (ORM)
+pattern[http://www.martinfowler.com/eaaCatalog/activeRecord.html] by the same
+name described by Martin Fowler:
+
+  "An object that wraps a row in a database table or view,
+  encapsulates the database access, and adds domain logic on that data."
+
+Active Record attempts to provide a coherent wrapper as a solution for the inconvenience that is
+object-relational mapping. The prime directive for this mapping has been to minimize
+the amount of code needed to build a real-world domain model. This is made possible
+by relying on a number of conventions that make it easy for Active Record to infer
+complex relations and structures from a minimal amount of explicit direction.
+
+Convention over Configuration:
+* No XML-files!
+* Lots of reflection and run-time extension
+* Magic is not inherently a bad word
+
+Admit the Database:
+* Lets you drop down to SQL for odd cases and performance
+* Doesn't attempt to duplicate or replace data definitions
+
+
+== Download and installation
+
+The latest version of Active Record can be installed with RubyGems:
+
+  % [sudo] gem install activerecord
+
+Source code can be downloaded as part of the Rails project on GitHub

+    # Now it's possible to access attributes from the database through the value objects instead. If
+    # you choose to name the composition the same as the attribute's name, it will be the only way to
+    # access that attribute. That's the case with our +balance+ attribute. You interact with the value
+    # objects just like you would any other attribute, though:
+    #
+    #   customer.balance = Money.new(20)     # sets the Money value object and the attribute
+    #   customer.balance                     # => Money value object
+    #   customer.balance.exchange_to("DKK")  # => Money.new(120, "DKK")
+    #   customer.balance > Money.new(10)     # => true
+    #   customer.balance == Money.new(20)    # => true
+    #   customer.balance < Money.new(5)      # => false
+    #
+    # Value objects can also be composed of multiple attributes, such as the case of Address. The order
+    # of the mappings will determine the order of the parameters.
+    #
+    #   customer.address_street = "Hyancintvej"
+    #   customer.address_city   = "Copenhagen"
+    #   customer.address        # => Address.new("Hyancintvej", "Copenhagen")
+    #   customer.address = Address.new("May Street", "Chicago")
+    #   customer.address_street # => "May Street"
+    #   customer.address_city   # => "Chicago"
+    #
+    # == Writing value objects
+    #
+    # Value objects are immutable and interchangeable objects that represent a given value, such as
+    # a Money object representing $5. Two Money objects both representing $5 should be equal (through
+    # methods such as <tt>==</tt> and <tt><=></tt> from Comparable if ranking makes sense). This is
+    # unlike entity objects where equality is determined by identity. An entity class such as Customer can
+    # easily have two different objects that both have an address on Hyancintvej. Entity identity is
+    # determined by object or relational unique identifiers (such as primary keys). Normal
+    # ActiveRecord::Base classes are entity objects.
+    #
+    # It's also important to treat the value objects as immutable. Don't allow the Money object to have
+    # its amount changed after creation. Create a new Money object with the new value instead. This
+    # is exemplified by the Money#exchange_to method that returns a new value object instead of changing
+    # its own values. Active Record won't persist value objects that have been changed through means
+    # other than the writer method.
+    #
+    # The immutable requirement is enforced by Active Record by freezing any object assigned as a value
+    # object. Attempting to change it afterwards will result in a ActiveSupport::FrozenObjectError.
+    #
+    # Read more about value objects on http://c2.com/cgi/wiki?ValueObject and on the dangers of not
+    # keeping value objects immutable on http://c2.com/cgi/wiki?ValueObjectsShouldBeImmutable
+    #
+    # == Custom constructors and converters
+    #
+    # By default value objects are initialized by calling the <tt>new</tt> constructor of the value
+    # class passing each of the mapped attributes, in the order specified by the <tt>:mapping</tt>
+    # option, as arguments. If the value class doesn't support this convention then +composed_of+ allows
+    # a custom constructor to be specified.
+    #
+    # When a new value is assigned to the value object the default assumption is that the new value
+    # is an instance of the value class. Specifying a custom converter allows the new value to be automatically
+    # converted to an instance of value class if necessary.
+    #
+    # For example, the NetworkResource model has +network_address+ and +cidr_range+ attributes that
+    # should be aggregated using the NetAddr::CIDR value class (http://netaddr.rubyforge.org). The constructor
+    # for the value class is called +create+ and it expects a CIDR address string as a parameter. New
+    # values can be assigned to the value object using either another NetAddr::CIDR object, a string
+    # or an array. The <tt>:constructor</tt> and <tt>:converter</tt> options can be used to meet
+    # these requirements:
+    #
+    #   class NetworkResource < ActiveRecord::Base
+    #     composed_of :cidr,
+    #                 :class_name => 'NetAddr::CIDR',
+    #                 :mapping => [ %w(network_address network), %w(cidr_range bits) ],
+    #                 :allow_nil => true,
+    #                 :constructor => Proc.new { |network_address, cidr_range| NetAddr::CIDR.create("#{network_address}/#{cidr_range}") },
+    #                 :converter => Proc.new { |value| NetAddr::CIDR.create(value.is_a?(Array) ? value.join('/') : value) }
+    #   end
+    #
+    #   # This calls the :constructor
+    #   network_resource = NetworkResource.new(:network_address => '192.168.0.1', :cidr_range => 24)
+    #
+    #   # These assignments will both use the :converter
+    #   network_resource.cidr = [ '192.168.2.1', 8 ]
+    #   network_resource.cidr = '192.168.0.1/24'
+    #
+    #   # This assignment won't use the :converter as the value is already an instance of the value class
+    #   network_resource.cidr = NetAddr::CIDR.create('192.168.2.1/8')
+    #
+    #   # Saving and then reloading will use the :constructor on reload
+    #   network_resource.save
+    #   network_resource.reload
+    #
+    # == Finding records by a value object
+    #
+    # Once a +composed_of+ relationship is specified for a model, records can be loaded from the database
+    # by specifying an instance of the value object in the conditions hash. The following example
+    # finds all customers with +balance_amount+ equal to 20 and +balance_currency+ equal to "USD":
+    #
+    #   Customer.where(:balance => Money.new(20, "USD")).all
+    #
+    module ClassMethods
+      # Adds reader and writer methods for manipulating a value object:
+      # <tt>composed_of :address</tt> adds <tt>address</tt> and <tt>address=(new_address)</tt> methods.
+      #
+      # Options are:
+      # * <tt>:class_name</tt> - Specifies the class name of the association. Use it only if that name
+      #   can't be inferred from the part id. So <tt>composed_of :address</tt> will by default be linked
+      #   to the Address class, but if the real class name is CompanyAddress, you'll have to specify it
+      #   with this option.
+      # * <tt>:mapping</tt> - Specifies the mapping of entity attributes to attributes of the value
+      #   object. Each mapping is represented as an array where the first item is the name of the
+      #   entity attribute and the second item is the name of the attribute in the value object. The
+      #   order in which mappings are defined determines the order in which attributes are sent to the
+      #   value class constructor.
+      # * <tt>:allow_nil</tt> - Specifies that the value object will not be instantiated when all mapped
+      #   attributes are +nil+. Setting the value object to +nil+ has the effect of writing +nil+ to all
+      #   mapped attributes.
+      #   This defaults to +false+.
+      # * <tt>:constructor</tt> - A symbol specifying the name of the constructor method or a Proc that
+      #   is called to initialize the value object. The constructor is passed all of the mapped attributes,
+      #   in the order that they are defined in the <tt>:mapping option</tt>, as arguments and uses them
+      #   to instantiate a <tt>:class_name</tt> object.
+      #   The default is <tt>:new</tt>.
+      # * <tt>:converter</tt> - A symbol specifying the name of a class method of <tt>:class_name</tt>
+      #   or a Proc that is called when a new value is assigned to the value object. The converter is
+      #   passed the single value that is used in the assignment and is only called if the new value is
+      #   not an instance of <tt>:class_name</tt>.
+      #
+      # Option examples:
+      #   composed_of :temperature, :mapping => %w(reading celsius)
+      #   composed_of :balance, :class_name => "Money", :mapping => %w(balance amount),
+      #                         :converter => Proc.new { |balance| balance.to_money }
+      #   composed_of :address, :mapping => [ %w(address_street street), %w(address_city city) ]
+      #   composed_of :gps_location
+      #   composed_of :gps_location, :allow_nil => true
+      #   composed_of :ip_address,
+      #               :class_name => 'IPAddr',
+      #               :mapping => %w(ip to_i),
+      #               :constructor => Proc.new { |ip| IPAddr.new(ip, Socket::AF_INET) },
+      #               :converter => Proc.new { |ip| ip.is_a?(Integer) ? IPAddr.new(ip, Socket::AF_INET) : IPAddr.new(ip.to_s) }
+      #

+    # about is available in <tt>@reflection</tt>. That's an instance of the class
+    # ActiveRecord::Reflection::AssociationReflection.
+    #
+    # For example, given

+    #     has_many :posts
+    #   end
+    #
+    #   blog = Blog.first

+    # the association proxy in <tt>blog.posts</tt> has the object in +blog+ as
+    # <tt>@owner</tt>, the collection of its posts as <tt>@target</tt>, and
+    # the <tt>@reflection</tt> object represents a <tt>:has_many</tt> macro.
+    #
+    # This class has most of the basic instance methods removed, and delegates
+    # unknown methods to <tt>@target</tt> via <tt>method_missing</tt>. As a
+    # corner case, it even removes the +class+ method and that's why you get

+    # Implements the details of eager loading of Active Record associations.
+    #
+    # Note that 'eager loading' and 'preloading' are actually the same thing.
+    # However, there are two different eager loading strategies.
+    #
+    # The first one is by using table joins. This was only strategy available
+    # prior to Rails 2.1. Suppose that you have an Author model with columns
+    # 'name' and 'age', and a Book model with columns 'name' and 'sales'. Using
+    # this strategy, Active Record would try to retrieve all data for an author
+    # and all of its books via a single query:
+    #
+    #   SELECT * FROM authors
+    #   LEFT OUTER JOIN books ON authors.id = books.id
+    #   WHERE authors.name = 'Ken Akamatsu'
+    #
+    # However, this could result in many rows that contain redundant data. After
+    # having received the first row, we already have enough data to instantiate
+    # the Author object. In all subsequent rows, only the data for the joined
+    # 'books' table is useful; the joined 'authors' data is just redundant, and
+    # processing this redundant data takes memory and CPU time. The problem
+    # quickly becomes worse and worse as the level of eager loading increases
+    # (i.e. if Active Record is to eager load the associations' associations as
+    # well).
+    #
+    # The second strategy is to use multiple database queries, one for each
+    # level of association. Since Rails 2.1, this is the default strategy. In
+    # situations where a table join is necessary (e.g. when the +:conditions+
+    # option references an association's column), it will fallback to the table
+    # join strategy.

+      # <tt>belongs_to :author</tt>, <tt>has_many :buyers</tt> has association
+      # names +:author+ and +:buyers+.
+      #
+      # == Parameters
+      # +records+ is an array of ActiveRecord::Base. This array needs not be flat,
+      # i.e. +records+ itself may also contain arrays of records. In any case,
+      # +preload_associations+ will preload the all associations records by
+      # flattening +records+.
+      #
+      # +associations+ specifies one or more associations that you want to
+      # preload. It may be:
+      # - a Symbol or a String which specifies a single association name. For
+      #   example, specifying +:books+ allows this method to preload all books
+      #   for an Author.
+      # - an Array which specifies multiple association names. This array
+      #   is processed recursively. For example, specifying <tt>[:avatar, :books]</tt>
+      #   allows this method to preload an author's avatar as well as all of his
+      #   books.
+      # - a Hash which specifies multiple association names, as well as
+      #   association names for the to-be-preloaded association objects. For
+      #   example, specifying <tt>{ :author => :avatar }</tt> will preload a
+      #   book's author, as well as that author's avatar.
+      #
+      # +:associations+ has the same format as the +:include+ option for
+      # <tt>ActiveRecord::Base.find</tt>. So +associations+ could look like this:
+      #
+      #   :books
+      #   [ :books, :author ]
+      #   { :author => :avatar }
+      #   [ :books, { :author => :avatar } ]
+      #
+      # +options+ contains options that will be passed to ActiveRecord::Base#find
+      # (which is called under the hood for preloading records). But it is passed
+      # only one level deep in the +associations+ argument, i.e. it's not passed
+      # to the child associations when +associations+ is a Hash.

+module ActiveRecord
+  # = Active Record Autosave Association
+  #
+  # +AutosaveAssociation+ is a module that takes care of automatically saving
+  # associated records when their parent is saved. In addition to saving, it
+  # also destroys any associated records that were marked for destruction.
+  # (See +mark_for_destruction+ and <tt>marked_for_destruction?</tt>).
+  #
+  # Saving of the parent, its associations, and the destruction of marked
+  # associations, all happen inside a transaction. This should never leave the
+  # database in an inconsistent state.
+  #
+  # If validations for any of the associations fail, their error messages will
+  # be applied to the parent.
+  #
+  # Note that it also means that associations marked for destruction won't
+  # be destroyed directly. They will however still be marked for destruction.
+  #
+  # Note that <tt>:autosave => false</tt> is not same as not declaring <tt>:autosave</tt>.
+  # When the <tt>:autosave</tt> option is not present new associations are saved.
+  #
+  # == Validation
+  #
+  # Children records are validated unless <tt>:validate</tt> is +false+.
+  #
+  # == Callbacks
+  #
+  # Association with autosave option defines several callbacks on your
+  # model (before_save, after_create, after_update). Please note that
+  # callbacks are executed in the order they were defined in
+  # model. You should avoid modyfing the association content, before
+  # autosave callbacks are executed. Placing your callbacks after
+  # associations is usually a good practice.
+  #
+  # == Examples
+  #
+  # === One-to-one Example
+  #
+  #   class Post
+  #     has_one :author, :autosave => true
+  #   end
+  #
+  # Saving changes to the parent and its associated model can now be performed
+  # automatically _and_ atomically:
+  #
+  #   post = Post.find(1)
+  #   post.title       # => "The current global position of migrating ducks"
+  #   post.author.name # => "alloy"
+  #
+  #   post.title = "On the migration of ducks"
+  #   post.author.name = "Eloy Duran"
+  #
+  #   post.save
+  #   post.reload
+  #   post.title       # => "On the migration of ducks"
+  #   post.author.name # => "Eloy Duran"
+  #
+  # Destroying an associated model, as part of the parent's save action, is as
+  # simple as marking it for destruction:
+  #
+  #   post.author.mark_for_destruction
+  #   post.author.marked_for_destruction? # => true
+  #
+  # Note that the model is _not_ yet removed from the database:
+  #
+  #   id = post.author.id
+  #   Author.find_by_id(id).nil? # => false
+  #
+  #   post.save
+  #   post.reload.author # => nil
+  #
+  # Now it _is_ removed from the database:
+  #
+  #   Author.find_by_id(id).nil? # => true
+  #
+  # === One-to-many Example
+  #
+  # When <tt>:autosave</tt> is not declared new children are saved when their parent is saved:
+  #
+  #   class Post
+  #     has_many :comments # :autosave option is no declared
+  #   end
+  #
+  #   post = Post.new(:title => 'ruby rocks')
+  #   post.comments.build(:body => 'hello world')
+  #   post.save # => saves both post and comment
+  #
+  #   post = Post.create(:title => 'ruby rocks')
+  #   post.comments.build(:body => 'hello world')
+  #   post.save # => saves both post and comment
+  #
+  #   post = Post.create(:title => 'ruby rocks')
+  #   post.comments.create(:body => 'hello world')
+  #   post.save # => saves both post and comment
+  #
+  # When <tt>:autosave</tt> is true all children is saved, no matter whether they are new records:
+  #
+  #   class Post
+  #     has_many :comments, :autosave => true
+  #   end
+  #
+  #   post = Post.create(:title => 'ruby rocks')
+  #   post.comments.create(:body => 'hello world')
+  #   post.comments[0].body = 'hi everyone'
+  #   post.save # => saves both post and comment, with 'hi everyone' as body
+  #
+  # Destroying one of the associated models as part of the parent's save action
+  # is as simple as marking it for destruction:
+  #
+  #   post.comments.last.mark_for_destruction
+  #   post.comments.last.marked_for_destruction? # => true
+  #   post.comments.length # => 2
+  #
+  # Note that the model is _not_ yet removed from the database:

+module ActiveRecord #:nodoc:
+  # = Active Record
+  #
+  # Active Record objects don't specify their attributes directly, but rather infer them from
+  # the table definition with which they're linked. Adding, removing, and changing attributes
+  # and their type is done directly in the database. Any change is instantly reflected in the
+  # Active Record objects. The mapping that binds a given Active Record class to a certain
+  # database table will happen automatically in most common cases, but can be overwritten for the uncommon ones.
+  #
+  # See the mapping rules in table_name and the full example in link:files/activerecord/README_rdoc.html for more insight.
+  #
+  # == Creation
+  #
+  # Active Records accept constructor parameters either in a hash or as a block. The hash
+  # method is especially useful when you're receiving the data from somewhere else, like an
+  # HTTP request. It works like this:
+  #
+  #   user = User.new(:name => "David", :occupation => "Code Artist")
+  #   user.name # => "David"
+  #
+  # You can also use block initialization:
+  #
+  #   user = User.new do |u|
+  #     u.name = "David"
+  #     u.occupation = "Code Artist"
+  #   end
+  #
+  # And of course you can just create a bare object and specify the attributes after the fact:
+  #
+  #   user = User.new
+  #   user.name = "David"
+  #   user.occupation = "Code Artist"
+  #
+  # == Conditions
+  #
+  # Conditions can either be specified as a string, array, or hash representing the WHERE-part of an SQL statement.
+  # The array form is to be used when the condition input is tainted and requires sanitization. The string form can
+  # be used for statements that don't involve tainted data. The hash form works much like the array form, except
+  # only equality and range is possible. Examples:
+  #
+  #   class User < ActiveRecord::Base
+  #     def self.authenticate_unsafely(user_name, password)
+  #       where("user_name = '#{user_name}' AND password = '#{password}'").first
+  #     end
+  #
+  #     def self.authenticate_safely(user_name, password)
+  #       where("user_name = ? AND password = ?", user_name, password).first
+  #     end
+  #
+  #     def self.authenticate_safely_simply(user_name, password)
+  #       where(:user_name => user_name, :password => password).first
+  #     end
+  #   end
+  #
+  # The <tt>authenticate_unsafely</tt> method inserts the parameters directly into the query
+  # and is thus susceptible to SQL-injection attacks if the <tt>user_name</tt> and +password+
+  # parameters come directly from an HTTP request. The <tt>authenticate_safely</tt> and
+  # <tt>authenticate_safely_simply</tt> both will sanitize the <tt>user_name</tt> and +password+
+  # before inserting them in the query, which will ensure that an attacker can't escape the
+  # query and fake the login (or worse).
+  #
+  # When using multiple parameters in the conditions, it can easily become hard to read exactly
+  # what the fourth or fifth question mark is supposed to represent. In those cases, you can
+  # resort to named bind variables instead. That's done by replacing the question marks with
+  # symbols and supplying a hash with values for the matching symbol keys:
+  #
+  #   Company.where(
+  #     "id = :id AND name = :name AND division = :division AND created_at > :accounting_date",
+  #     { :id => 3, :name => "37signals", :division => "First", :accounting_date => '2005-01-01' }
+  #   ).first
+  #
+  # Similarly, a simple hash without a statement will generate conditions based on equality with the SQL AND
+  # operator. For instance:
+  #
+  #   Student.where(:first_name => "Harvey", :status => 1)
+  #   Student.where(params[:student])
+  #
+  # A range may be used in the hash to use the SQL BETWEEN operator:
+  #
+  #   Student.where(:grade => 9..12)
+  #
+  # An array may be used in the hash to use the SQL IN operator:
+  #
+  #   Student.where(:grade => [9,11,12])
+  #
+  # When joining tables, nested hashes or keys written in the form 'table_name.column_name'
+  # can be used to qualify the table name of a particular condition. For instance:
+  #
+  #   Student.joins(:schools).where(:schools => { :category => 'public' })
+  #   Student.joins(:schools).where('schools.category' => 'public' )
+  #
+  # == Overwriting default accessors
+  #
+  # All column values are automatically available through basic accessors on the Active Record
+  # object, but sometimes you want to specialize this behavior. This can be done by overwriting
+  # the default accessors (using the same name as the attribute) and calling
+  # <tt>read_attribute(attr_name)</tt> and <tt>write_attribute(attr_name, value)</tt> to actually
+  # change things.
+  #
+  #   class Song < ActiveRecord::Base
+  #     # Uses an integer of seconds to hold the length of the song
+  #
+  #     def length=(minutes)
+  #       write_attribute(:length, minutes.to_i * 60)
+  #     end
+  #
+  #     def length
+  #       read_attribute(:length) / 60
+  #     end
+  #   end
+  #
+  # You can alternatively use <tt>self[:attribute]=(value)</tt> and <tt>self[:attribute]</tt>
+  # instead of <tt>write_attribute(:attribute, value)</tt> and <tt>read_attribute(:attribute)</tt>.
+  #
+  # == Attribute query methods
+  #
+  # In addition to the basic accessors, query methods are also automatically available on the Active Record object.
+  # Query methods allow you to test whether an attribute value is present.
+  #
+  # For example, an Active Record User with the <tt>name</tt> attribute has a <tt>name?</tt> method that you can call
+  # to determine whether the user has a name:
+  #
+  #   user = User.new(:name => "David")
+  #   user.name? # => true
+  #
+  #   anonymous = User.new(:name => "")
+  #   anonymous.name? # => false
+  #
+  # == Accessing attributes before they have been typecasted
+  #
+  # Sometimes you want to be able to read the raw attribute data without having the column-determined
+  # typecast run its course first. That can be done by using the <tt><attribute>_before_type_cast</tt>
+  # accessors that all attributes have. For example, if your Account model has a <tt>balance</tt> attribute,
+  # you can call <tt>account.balance_before_type_cast</tt> or <tt>account.id_before_type_cast</tt>.
+  #
+  # This is especially useful in validation situations where the user might supply a string for an
+  # integer field and you want to display the original string back in an error message. Accessing the
+  # attribute normally would typecast the string to 0, which isn't what you want.
+  #
+  # == Dynamic attribute-based finders
+  #
+  # Dynamic attribute-based finders are a cleaner way of getting (and/or creating) objects
+  # by simple queries without turning to SQL. They work by appending the name of an attribute
+  # to <tt>find_by_</tt>, <tt>find_last_by_</tt>, or <tt>find_all_by_</tt> and thus produces finders
+  # like <tt>Person.find_by_user_name</tt>, <tt>Person.find_all_by_last_name</tt>, and
+  # <tt>Payment.find_by_transaction_id</tt>. Instead of writing
+  # <tt>Person.where(:user_name => user_name).first</tt>, you just do <tt>Person.find_by_user_name(user_name)</tt>.
+  # And instead of writing <tt>Person.where(:last_name => last_name).all</tt>, you just do
+  # <tt>Person.find_all_by_last_name(last_name)</tt>.
+  #
+  # It's possible to add an exclamation point (!) on the end of the dynamic finders to get them to raise an
+  # <tt>ActiveRecord::RecordNotFound</tt> error if they do not return any records,
+  # like <tt>Person.find_by_last_name!</tt>.
+  #
+  # It's also possible to use multiple attributes in the same find by separating them with "_and_".
+  #
+  #  Person.where(:user_name => user_name, :password => password).first
+  #  Person.find_by_user_name_and_password(user_name, password) # with dynamic finder
+  #
+  # It's even possible to call these dynamic finder methods on relations and named scopes.
+  #
+  #   Payment.order("created_on").find_all_by_amount(50)
+  #   Payment.pending.find_last_by_amount(100)
+  #
+  # The same dynamic finder style can be used to create the object if it doesn't already exist.
+  # This dynamic finder is called with <tt>find_or_create_by_</tt> and will return the object if
+  # it already exists and otherwise creates it, then returns it. Protected attributes won't be set
+  # unless they are given in a block.
+  #
+  #   # No 'Summer' tag exists
+  #   Tag.find_or_create_by_name("Summer") # equal to Tag.create(:name => "Summer")
+  #
+  #   # Now the 'Summer' tag does exist
+  #   Tag.find_or_create_by_name("Summer") # equal to Tag.find_by_name("Summer")
+  #
+  #   # Now 'Bob' exist and is an 'admin'
+  #   User.find_or_create_by_name('Bob', :age => 40) { |u| u.admin = true }
+  #
+  # Use the <tt>find_or_initialize_by_</tt> finder if you want to return a new record without
+  # saving it first. Protected attributes won't be set unless they are given in a block.
+  #
+  #   # No 'Winter' tag exists
+  #   winter = Tag.find_or_initialize_by_name("Winter")
+  #   winter.persisted? # false
+  #
+  # To find by a subset of the attributes to be used for instantiating a new object, pass a hash instead of
+  # a list of parameters.
+  #
+  #   Tag.find_or_create_by_name(:name => "rails", :creator => current_user)
+  #
+  # That will either find an existing tag named "rails", or create a new one while setting the
+  # user that created it.
+  #
+  # Just like <tt>find_by_*</tt>, you can also use <tt>scoped_by_*</tt> to retrieve data. The good thing about
+  # using this feature is that the very first time result is returned using <tt>method_missing</tt> technique
+  # but after that the method is declared on the class. Henceforth <tt>method_missing</tt> will not be hit.
+  #
+  #  User.scoped_by_user_name('David')
+  #
+  # == Saving arrays, hashes, and other non-mappable objects in text columns
+  #
+  # Active Record can serialize any object in text columns using YAML. To do so, you must
+  # specify this with a call to the class method +serialize+.
+  # This makes it possible to store arrays, hashes, and other non-mappable objects without doing
+  # any additional work.
+  #
+  #   class User < ActiveRecord::Base
+  #     serialize :preferences
+  #   end
+  #
+  #   user = User.create(:preferences => { "background" => "black", "display" => large })

+  #
+  # == Single table inheritance
+  #
+  # Active Record allows inheritance by storing the name of the class in a column that by
+  # default is named "type" (can be changed by overwriting <tt>Base.inheritance_column</tt>).
+  # This means that an inheritance looking like this:
+  #
+  #   class Company < ActiveRecord::Base; end
+  #   class Firm < Company; end
+  #   class Client < Company; end
+  #   class PriorityClient < Client; end
+  #
+  # When you do <tt>Firm.create(:name => "37signals")</tt>, this record will be saved in
+  # the companies table with type = "Firm". You can then fetch this row again using
+  # <tt>Company.where(:name => '37signals').first</tt> and it will return a Firm object.
+  #
+  # If you don't have a type column defined in your table, single-table inheritance won't
+  # be triggered. In that case, it'll work just like normal subclasses with no special magic
+  # for differentiating between them or reloading the right type with find.
+  #
+  # Note, all the attributes for all the cases are kept in the same table. Read more:
+  # http://www.martinfowler.com/eaaCatalog/singleTableInheritance.html
+  #
+  # == Connection to multiple databases in different models
+  #
+  # Connections are usually created through ActiveRecord::Base.establish_connection and retrieved
+  # by ActiveRecord::Base.connection. All classes inheriting from ActiveRecord::Base will use this
+  # connection. But you can also set a class-specific connection. For example, if Course is an
+  # ActiveRecord::Base, but resides in a different database, you can just say <tt>Course.establish_connection</tt>
+  # and Course and all of its subclasses will use this connection instead.
+  #
+  # This feature is implemented by keeping a connection pool in ActiveRecord::Base that is
+  # a Hash indexed by the class. If a connection is requested, the retrieve_connection method
+  # will go up the class-hierarchy until a connection is found in the connection pool.
+  #
+  # == Exceptions
+  #
+  # * ActiveRecordError - Generic error class and superclass of all other errors raised by Active Record.
+  # * AdapterNotSpecified - The configuration hash used in <tt>establish_connection</tt> didn't include an
+  #   <tt>:adapter</tt> key.
+  # * AdapterNotFound - The <tt>:adapter</tt> key used in <tt>establish_connection</tt> specified a
+  #   non-existent adapter
+  #   (or a bad spelling of an existing one).
+  # * AssociationTypeMismatch - The object assigned to the association wasn't of the type
+  #   specified in the association definition.
+  # * SerializationTypeMismatch - The serialized object wasn't of the class specified as the second parameter.
+  # * ConnectionNotEstablished+ - No connection has been established. Use <tt>establish_connection</tt>
+  #   before querying.
+  # * RecordNotFound - No record responded to the +find+ method. Either the row with the given ID doesn't exist
+  #   or the row didn't meet the additional restrictions. Some +find+ calls do not raise this exception to signal
+  #   nothing was found, please check its documentation for further details.
+  # * StatementInvalid - The database server rejected the SQL statement. The precise error is added in the message.
+  # * MultiparameterAssignmentErrors - Collection of errors that occurred during a mass assignment using the
+  #   <tt>attributes=</tt> method. The +errors+ property of this exception contains an array of
+  #   AttributeAssignmentError
+  #   objects that should be inspected to determine which attributes triggered the errors.
+  # * AttributeAssignmentError - An error occurred while doing a mass assignment through the
+  #   <tt>attributes=</tt> method.
+  #   You can inspect the +attribute+ property of the exception object to determine which attribute
+  #   triggered the error.
+  #
+  # *Note*: The attributes listed are class-level attributes (accessible from both the class and instance level).
+  # So it's possible to assign a logger to the class through <tt>Base.logger=</tt> which will then be used by all
+  # instances in the current object space.

+  # = Active Record Callbacks
+  #
+  # Callbacks are hooks into the life cycle of an Active Record object that allow you to trigger logic
+  # before or after an alteration of the object state. This can be used to make sure that associated and
+  # dependent objects are deleted when +destroy+ is called (by overwriting +before_destroy+) or to massage attributes
+  # before they're validated (by overwriting +before_validation+). As an example of the callbacks initiated, consider
+  # the <tt>Base#save</tt> call for a new record:
+  #
+  # * (-) <tt>save</tt>
+  # * (-) <tt>valid</tt>
+  # * (1) <tt>before_validation</tt>
+  # * (-) <tt>validate</tt>
+  # * (2) <tt>after_validation</tt>
+  # * (3) <tt>before_save</tt>
+  # * (4) <tt>before_create</tt>
+  # * (-) <tt>create</tt>
+  # * (5) <tt>after_create</tt>
+  # * (6) <tt>after_save</tt>
+  # * (7) <tt>after_commit</tt>
+  #
+  # Also, an <tt>after_rollback</tt> callback can be configured to be triggered whenever a rollback is issued.
+  # Check out <tt>ActiveRecord::Transactions</tt> for more details about <tt>after_commit</tt> and
+  # <tt>after_rollback</tt>.
+  #
+  # Lastly an <tt>after_find</tt> and <tt>after_initialize</tt> callback is triggered for each object that 
+  # is found and instantiated by a finder, with <tt>after_initialize</tt> being triggered after new objects
+  # are instantiated as well.
+  #
+  # That's a total of twelve callbacks, which gives you immense power to react and prepare for each state in the
+  # Active Record life cycle. The sequence for calling <tt>Base#save</tt> for an existing record is similar,
+  # except that each <tt>_create</tt> callback is replaced by the corresponding <tt>_update</tt> callback.
+  #
+  # Examples:
+  #   class CreditCard < ActiveRecord::Base
+  #     # Strip everything but digits, so the user can specify "555 234 34" or
+  #     # "5552-3434" or both will mean "55523434"
+  #     before_validation(:on => :create) do
+  #       self.number = number.gsub(/[^0-9]/, "") if attribute_present?("number")
+  #     end
+  #   end
+  #
+  #   class Subscription < ActiveRecord::Base
+  #     before_create :record_signup
+  #
+  #     private
+  #       def record_signup
+  #         self.signed_up_on = Date.today
+  #       end

+  #     before_destroy { |record| Client.destroy_all "client_of = #{record.id}" }
+  #   end
+  #
+  # == Inheritable callback queues
+  #
+  # Besides the overwritable callback methods, it's also possible to register callbacks through the
+  # use of the callback macros. Their main advantage is that the macros add behavior into a callback
+  # queue that is kept intact down through an inheritance hierarchy.
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy :destroy_author
+  #   end
+  #
+  #   class Reply < Topic
+  #     before_destroy :destroy_readers
+  #   end
+  #
+  # Now, when <tt>Topic#destroy</tt> is run only +destroy_author+ is called. When <tt>Reply#destroy</tt> is
+  # run, both +destroy_author+ and +destroy_readers+ are called. Contrast this to the following situation
+  # where the +before_destroy+ method is overridden:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     def before_destroy() destroy_author end
+  #   end
+  #
+  #   class Reply < Topic
+  #     def before_destroy() destroy_readers end
+  #   end
+  #
+  # In that case, <tt>Reply#destroy</tt> would only run +destroy_readers+ and _not_ +destroy_author+.
+  # So, use the callback macros when you want to ensure that a certain callback is called for the entire
+  # hierarchy, and use the regular overwriteable methods when you want to leave it up to each descendant
+  # to decide whether they want to call +super+ and trigger the inherited callbacks.
+  #
+  # *IMPORTANT:* In order for inheritance to work for the callback queues, you must specify the
+  # callbacks before specifying the associations. Otherwise, you might trigger the loading of a
+  # child before the parent has registered the callbacks and they won't be inherited.
+  #
+  # == Types of callbacks
+  #
+  # There are four types of callbacks accepted by the callback macros: Method references (symbol), callback objects,
+  # inline methods (using a proc), and inline eval methods (using a string). Method references and callback objects
+  # are the recommended approaches, inline methods using a proc are sometimes appropriate (such as for
+  # creating mix-ins), and inline eval methods are deprecated.
+  #
+  # The method reference callbacks work by specifying a protected or private method available in the object, like this:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy :delete_parents
+  #
+  #     private
+  #       def delete_parents
+  #         self.class.delete_all "parent_id = #{id}"
+  #       end
+  #   end
+  #
+  # The callback objects have methods named after the callback called with the record as the only parameter, such as:
+  #
+  #   class BankAccount < ActiveRecord::Base
+  #     before_save      EncryptionWrapper.new
+  #     after_save       EncryptionWrapper.new
+  #     after_initialize EncryptionWrapper.new
+  #   end
+  #
+  #   class EncryptionWrapper
+  #     def before_save(record)
+  #       record.credit_card_number = encrypt(record.credit_card_number)
+  #     end
+  #
+  #     def after_save(record)
+  #       record.credit_card_number = decrypt(record.credit_card_number)
+  #     end
+  #
+  #     alias_method :after_find, :after_save
+  #
+  #     private
+  #       def encrypt(value)
+  #         # Secrecy is committed
+  #       end
+  #
+  #       def decrypt(value)
+  #         # Secrecy is unveiled
+  #       end
+  #   end
+  #
+  # So you specify the object you want messaged on a given callback. When that callback is triggered, the object has
+  # a method by the name of the callback messaged. You can make these callbacks more flexible by passing in other
+  # initialization data such as the name of the attribute to work with:
+  #
+  #   class BankAccount < ActiveRecord::Base
+  #     before_save      EncryptionWrapper.new("credit_card_number")
+  #     after_save       EncryptionWrapper.new("credit_card_number")
+  #     after_initialize EncryptionWrapper.new("credit_card_number")
+  #   end
+  #
+  #   class EncryptionWrapper
+  #     def initialize(attribute)
+  #       @attribute = attribute
+  #     end
+  #
+  #     def before_save(record)
+  #       record.send("#{@attribute}=", encrypt(record.send("#{@attribute}")))
+  #     end
+  #
+  #     def after_save(record)
+  #       record.send("#{@attribute}=", decrypt(record.send("#{@attribute}")))
+  #     end
+  #
+  #     alias_method :after_find, :after_save
+  #
+  #     private
+  #       def encrypt(value)
+  #         # Secrecy is committed
+  #       end
+  #
+  #       def decrypt(value)
+  #         # Secrecy is unveiled
+  #       end
+  #   end
+  #
+  # The callback macros usually accept a symbol for the method they're supposed to run, but you can also
+  # pass a "method string", which will then be evaluated within the binding of the callback. Example:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy 'self.class.delete_all "parent_id = #{id}"'
+  #   end
+  #
+  # Notice that single quotes (') are used so the <tt>#{id}</tt> part isn't evaluated until the callback
+  # is triggered. Also note that these inline callbacks can be stacked just like the regular ones:
+  #
+  #   class Topic < ActiveRecord::Base
+  #     before_destroy 'self.class.delete_all "parent_id = #{id}"',
+  #                    'puts "Evaluated after parents are destroyed"'
+  #   end
+  #
+  # == <tt>before_validation*</tt> returning statements
+  #
+  # If the returning value of a +before_validation+ callback can be evaluated to +false+, the process will be
+  # aborted and <tt>Base#save</tt> will return +false+. If Base#save! is called it will raise a
+  # ActiveRecord::RecordInvalid exception. Nothing will be appended to the errors object.
+  #
+  # == Canceling callbacks
+  #
+  # If a <tt>before_*</tt> callback returns +false+, all the later callbacks and the associated action are
+  # cancelled. If an <tt>after_*</tt> callback returns +false+, all the later callbacks are cancelled.
+  # Callbacks are generally run in the order they are defined, with the exception of callbacks defined as
+  # methods on the model, which are called last.
+  #
+  # == Transactions
+  #
+  # The entire callback chain of a +save+, <tt>save!</tt>, or +destroy+ call runs
+  # within a transaction. That includes <tt>after_*</tt> hooks. If everything
+  # goes fine a COMMIT is executed once the chain has been completed.
+  #
+  # If a <tt>before_*</tt> callback cancels the action a ROLLBACK is issued. You
+  # can also trigger a ROLLBACK raising an exception in any of the callbacks,
+  # including <tt>after_*</tt> hooks. Note, however, that in that case the client
+  # needs to be aware of it because an ordinary +save+ will raise such exception
+  # instead of quietly returning +false+.
+  #
+  # == Debugging callbacks
+  # 
+  # The callback chain is accessible via the <tt>_*_callbacks</tt> method on an object. ActiveModel Callbacks support 
+  # <tt>:before</tt>, <tt>:after</tt> and <tt>:around</tt> as values for the <tt>kind</tt> property. The <tt>kind</tt> property
+  # defines what part of the chain the callback runs in.
+  # 
+  # To find all callbacks in the before_save callback chain: 
+  # 
+  #   Topic._save_callbacks.select { |cb| cb.kind.eql?(:before) }
+  # 
+  # Returns an array of callback objects that form the before_save chain.
+  # 
+  # To further check if the before_save chain contains a proc defined as <tt>rest_when_dead</tt> use the <tt>filter</tt> property of the callback object:
+  # 
+  #   Topic._save_callbacks.select { |cb| cb.kind.eql?(:before) }.collect(&:filter).include?(:rest_when_dead)
+  # 
+  # Returns true or false depending on whether the proc is contained in the before_save callback chain on a Topic model.

+  end
+
+  module ConnectionAdapters
+    # Connection pool base class for managing Active Record database
+    # connections.
+    #
+    # == Introduction
+    #
+    # A connection pool synchronizes thread access to a limited number of
+    # database connections. The basic idea is that each thread checks out a
+    # database connection from the pool, uses that connection, and checks the
+    # connection back in. ConnectionPool is completely thread-safe, and will
+    # ensure that a connection cannot be used by two threads at the same time,
+    # as long as ConnectionPool's contract is correctly followed. It will also
+    # handle cases in which there are more threads than connections: if all
+    # connections have been checked out, and a thread tries to checkout a
+    # connection anyway, then ConnectionPool will wait until some other thread
+    # has checked in a connection.
+    #
+    # == Obtaining (checking out) a connection
+    #
+    # Connections can be obtained and used from a connection pool in several
+    # ways:
+    #
+    # 1. Simply use ActiveRecord::Base.connection as with Active Record 2.1 and
+    #    earlier (pre-connection-pooling). Eventually, when you're done with
+    #    the connection(s) and wish it to be returned to the pool, you call
+    #    ActiveRecord::Base.clear_active_connections!. This will be the
+    #    default behavior for Active Record when used in conjunction with
+    #    Action Pack's request handling cycle.
+    # 2. Manually check out a connection from the pool with
+    #    ActiveRecord::Base.connection_pool.checkout. You are responsible for
+    #    returning this connection to the pool when finished by calling
+    #    ActiveRecord::Base.connection_pool.checkin(connection).
+    # 3. Use ActiveRecord::Base.connection_pool.with_connection(&block), which
+    #    obtains a connection, yields it as the sole argument to the block,
+    #    and returns it to the pool after the block completes.
+    #
+    # Connections in the pool are actually AbstractAdapter objects (or objects
+    # compatible with AbstractAdapter's interface).
+    #
+    # == Options
+    #
+    # There are two connection-pooling-related options that you can add to
+    # your database connection configuration:
+    #
+    # * +pool+: number indicating size of connection pool (default 5)
+    # * +wait_timeout+: number of seconds to block and wait for a connection
+    #   before giving up and raising a timeout error (default 5 seconds).

+    #
+    #  |
+    #  +-- Book

+    # same connection pool. However, the connection pool used by Author/BankAccount
+    # is not the same as the one used by Book/ScaryBook/GoodBook.

+      # of nested transactions, by using savepoints:
+      # http://dev.mysql.com/doc/refman/5.0/en/savepoint.html
+      # Savepoints are supported by MySQL and PostgreSQL, but not SQLite3.
+      #
+      # It is safe to call this method if a database transaction is already open,
+      # i.e. if #transaction is called within another #transaction block. In case
+      # of a nested call, #transaction will behave as follows:
+      #
+      # - The block will be run without doing anything. All database statements
+      #   that happen within the block are effectively appended to the already
+      #   open database transaction.
+      # - However, if +:requires_new+ is set, the block will be wrapped in a
+      #   database savepoint acting as a sub-transaction.
+      #
+      # === Caveats
+      #
+      # MySQL doesn't support DDL transactions. If you perform a DDL operation,
+      # then any created savepoints will be automatically released. For example,
+      # if you've created a savepoint, then you execute a CREATE TABLE statement,
+      # then the savepoint that was created will be automatically released.
+      #
+      # This means that, on MySQL, you shouldn't execute DDL operations inside
+      # a #transaction call that you know might create a savepoint. Otherwise,
+      # #transaction will raise exceptions when it tries to release the
+      # already-automatically-released savepoints:
+      #
+      #   Model.connection.transaction do  # BEGIN
+      #     Model.connection.transaction(:requires_new => true) do  # CREATE SAVEPOINT active_record_1
+      #       Model.connection.create_table(...)
+      #       # active_record_1 now automatically released
+      #     end  # RELEASE SAVEPOINT active_record_1  <--- BOOM! database error!

+      # <tt>:integer</tt>, <tt>:float</tt>, <tt>:decimal</tt>,
+      # <tt>:datetime</tt>, <tt>:timestamp</tt>, <tt>:time</tt>,
+      # <tt>:date</tt>, <tt>:binary</tt>, <tt>:boolean</tt>.
+      #
+      # You may use a type not in this list as long as it is supported by your
+      # database (for example, "polygon" in MySQL), but this will not be database
+      # agnostic and should usually be avoided.
+      #
+      # Available options are (none of these exists by default):
+      # * <tt>:limit</tt> -
+      #   Requests a maximum column length. This is number of characters for <tt>:string</tt> and
+      #   <tt>:text</tt> columns and number of bytes for <tt>:binary</tt> and <tt>:integer</tt> columns.
+      # * <tt>:default</tt> -
+      #   The column's default value. Use nil for NULL.
+      # * <tt>:null</tt> -
+      #   Allows or disallows +NULL+ values in the column. This option could
+      #   have been named <tt>:null_allowed</tt>.
+      # * <tt>:precision</tt> -
+      #   Specifies the precision for a <tt>:decimal</tt> column.
+      # * <tt>:scale</tt> -
+      #   Specifies the scale for a <tt>:decimal</tt> column.
+      #
+      # For clarity's sake: the precision is the number of significant digits,
+      # while the scale is the number of digits that can be stored following
+      # the decimal point. For example, the number 123.45 has a precision of 5
+      # and a scale of 2. A decimal with a precision of 5 and a scale of 2 can
+      # range from -999.99 to 999.99.
+      #
+      # Please be aware of different RDBMS implementations behavior with
+      # <tt>:decimal</tt> columns:
+      # * The SQL standard says the default scale should be 0, <tt>:scale</tt> <=
+      #   <tt>:precision</tt>, and makes no comments about the requirements of
+      #   <tt>:precision</tt>.
+      # * MySQL: <tt>:precision</tt> [1..63], <tt>:scale</tt> [0..30].
+      #   Default is (10,0).
+      # * PostgreSQL: <tt>:precision</tt> [1..infinity],
+      #   <tt>:scale</tt> [0..infinity]. No default.
+      # * SQLite2: Any <tt>:precision</tt> and <tt>:scale</tt> may be used.
+      #   Internal storage as strings. No default.
+      # * SQLite3: No restrictions on <tt>:precision</tt> and <tt>:scale</tt>,
+      #   but the maximum supported <tt>:precision</tt> is 16. No default.
+      # * Oracle: <tt>:precision</tt> [1..38], <tt>:scale</tt> [-84..127].
+      #   Default is (38,0).
+      # * DB2: <tt>:precision</tt> [1..63], <tt>:scale</tt> [0..62].
+      #   Default unknown.
+      # * Firebird: <tt>:precision</tt> [1..18], <tt>:scale</tt> [0..18].
+      #   Default (9,0). Internal types NUMERIC and DECIMAL have different
+      #   storage rules, decimal being better.
+      # * FrontBase?: <tt>:precision</tt> [1..38], <tt>:scale</tt> [0..38].
+      #   Default (38,0). WARNING Max <tt>:precision</tt>/<tt>:scale</tt> for

+      # * SqlServer?: <tt>:precision</tt> [1..38], <tt>:scale</tt> [0..38].

+      # == Examples
+      #  # Assuming +td+ is an instance of TableDefinition
+      #  td.column(:granted, :boolean)
+      #  # granted BOOLEAN
+      #
+      #  td.column(:picture, :binary, :limit => 2.megabytes)
+      #  # => picture BLOB(2097152)
+      #
+      #  td.column(:sales_stage, :string, :limit => 20, :default => 'new', :null => false)
+      #  # => sales_stage VARCHAR(20) DEFAULT 'new' NOT NULL
+      #
+      #  td.column(:bill_gates_money, :decimal, :precision => 15, :scale => 2)
+      #  # => bill_gates_money DECIMAL(15,2)
+      #
+      #  td.column(:sensor_reading, :decimal, :precision => 30, :scale => 20)
+      #  # => sensor_reading DECIMAL(30,20)
+      #
+      #  # While <tt>:scale</tt> defaults to zero on most databases, it
+      #  # probably wouldn't hurt to include it.
+      #  td.column(:huge_integer, :decimal, :precision => 30)
+      #  # => huge_integer DECIMAL(30)
+      #
+      #  # Defines a column with a database-specific type.
+      #  td.column(:foo, 'polygon')
+      #  # => foo polygon
+      #
+      # == Short-hand examples
+      #
+      # Instead of calling +column+ directly, you can also work with the short-hand definitions for the default types.
+      # They use the type as the method name instead of as a parameter and allow for multiple columns to be defined
+      # in a single statement.
+      #
+      # What can be written like this with the regular calls to column:
+      #
+      #   create_table "products", :force => true do |t|
+      #     t.column "shop_id",    :integer
+      #     t.column "creator_id", :integer
+      #     t.column "name",       :string,   :default => "Untitled"
+      #     t.column "value",      :string,   :default => "Untitled"
+      #     t.column "created_at", :datetime
+      #     t.column "updated_at", :datetime
+      #   end
+      #
+      # Can also be written as follows using the short-hand:
+      #
+      #   create_table :products do |t|
+      #     t.integer :shop_id, :creator_id
+      #     t.string  :name, :value, :default => "Untitled"
+      #     t.timestamps
+      #   end
+      #
+      # There's a short-hand method for each of the type values declared at the top. And then there's
+      # TableDefinition#timestamps that'll add +created_at+ and +updated_at+ as datetimes.
+      #
+      # TableDefinition#references will add an appropriately-named _id column, plus a corresponding _type
+      # column if the <tt>:polymorphic</tt> option is supplied. If <tt>:polymorphic</tt> is a hash of
+      # options, these will be used when creating the <tt>_type</tt> column. So what can be written like this:
+      #
+      #   create_table :taggings do |t|
+      #     t.integer :tag_id, :tagger_id, :taggable_id
+      #     t.string  :tagger_type
+      #     t.string  :taggable_type, :default => 'Photo'
+      #   end
+      #
+      # Can also be written as follows using references:
+      #
+      #   create_table :taggings do |t|
+      #     t.references :tag
+      #     t.references :tagger, :polymorphic => true

+      #  # create_table() passes a TableDefinition object to the block.
+      #  # This form will not only create the table, but also columns for the
+      #  # table.
+      #
+      #  create_table(:suppliers) do |t|
+      #    t.column :name, :string, :limit => 60
+      #    # Other fields here
+      #  end
+      #
+      # === Block form, with shorthand
+      #  # You can also use the column types as method calls, rather than calling the column method.
+      #  create_table(:suppliers) do |t|
+      #    t.string :name, :limit => 60
+      #    # Other fields here
+      #  end
+      #
+      # === Regular form
+      #  # Creates a table called 'suppliers' with no columns.
+      #  create_table(:suppliers)
+      #  # Add a column to 'suppliers'.
+      #  add_column(:suppliers, :name, :string, {:limit => 60})
+      #
+      # The +options+ hash can include the following keys:
+      # [<tt>:id</tt>]
+      #   Whether to automatically add a primary key column. Defaults to true.
+      #   Join tables for +has_and_belongs_to_many+ should set it to false.
+      # [<tt>:primary_key</tt>]
+      #   The name of the primary key, if one is to be added automatically.
+      #   Defaults to +id+. If <tt>:id</tt> is false this option is ignored.
+      #
+      #   Also note that this just sets the primary key in the table. You additionally
+      #   need to configure the primary key in the model via +self.primary_key=+.
+      #   Models do NOT auto-detect the primary key from their table definition.
+      #
+      # [<tt>:options</tt>]
+      #   Any extra options you want appended to the table definition.
+      # [<tt>:temporary</tt>]
+      #   Make a temporary table.
+      # [<tt>:force</tt>]
+      #   Set to true to drop the table before creating it.

+    # with the given ID, altering the given hash of counters by the amount
+    # given by the corresponding value:
+    #
+    # ==== Parameters
+    #
+    # * +id+ - The id of the object you wish to update a counter on or an Array of ids.
+    # * +counters+ - An Array of Hashes containing the names of the fields
+    #   to update as keys and the amount to update the field by as values.
+    #
+    # ==== Examples
+    #
+    #   # For the Post with id of 5, decrement the comment_count by 1, and
+    #   # increment the action_count by 1
+    #   Post.update_counters 5, :comment_count => -1, :action_count => 1

+  # The fixture file ends with the <tt>.yml</tt> file extension (Rails example:
+  # <tt><your-rails-app>/test/fixtures/web_sites.yml</tt>). The format of a fixture file looks
+  # like this:
+  #
+  #   rubyonrails:
+  #     id: 1
+  #     name: Ruby on Rails
+  #     url: http://www.rubyonrails.org
+  #
+  #   google:
+  #     id: 2
+  #     name: Google
+  #     url: http://www.google.com
+  #
+  # This fixture file includes two fixtures. Each YAML fixture (ie. record) is given a name and
+  # is followed by an indented list of key/value pairs in the "key: value" format. Records are
+  # separated by a blank line for your viewing pleasure.
+  #
+  # Note that fixtures are unordered. If you want ordered fixtures, use the omap YAML type.
+  # See http://yaml.org/type/omap.html
+  # for the specification. You will need ordered fixtures when you have foreign key constraints
+  # on keys in the same table. This is commonly needed for tree structures. Example:
+  #
+  #    --- !omap
+  #    - parent:

+  # = Using Fixtures in Test Cases
+  #
+  # Since fixtures are a testing construct, we use them in our unit and functional tests. There
+  # are two ways to use the fixtures, but first let's take a look at a sample unit test:
+  #
+  #   require 'test_helper'
+  #
+  #   class WebSiteTest < ActiveSupport::TestCase
+  #     test "web_site_count" do
+  #       assert_equal 2, WebSite.count
+  #     end
+  #   end
+  #
+  # By default, <tt>test_helper.rb</tt> will load all of your fixtures into your test database,
+  # so this test will succeed.
+  #
+  # The testing environment will automatically load the all fixtures into the database before each
+  # test. To ensure consistent data, the environment deletes the fixtures before running the load.
+  #
+  # In addition to being available in the database, the fixture's data may also be accessed by
+  # using a special dynamic method, which has the same name as the model, and accepts the
+  # name of the fixture to instantiate:
+  #
+  #   test "find" do
+  #     assert_equal "Ruby on Rails", web_sites(:rubyonrails).name
+  #   end
+  #
+  # Alternatively, you may enable auto-instantiation of the fixture data. For instance, take the
+  # following tests:
+  #
+  #   test "find_alt_method_1" do
+  #     assert_equal "Ruby on Rails", @web_sites['rubyonrails']['name']
+  #   end
+  #
+  #   test "find_alt_method_2" do
+  #     assert_equal "Ruby on Rails", @rubyonrails.news
+  #   end
+  #
+  # In order to use these methods to access fixtured data within your testcases, you must specify one of the
+  # following in your <tt>ActiveSupport::TestCase</tt>-derived class:
+  #
+  # - to fully enable instantiated fixtures (enable alternate methods #1 and #2 above)
+  #     self.use_instantiated_fixtures = true
+  #
+  # - create only the hash for the fixtures, do not 'find' each instance (enable alternate method #1 only)
+  #     self.use_instantiated_fixtures = :no_instances
+  #
+  # Using either of these alternate methods incurs a performance hit, as the fixtured data must be fully
+  # traversed in the database to create the fixture hash and/or instance variables. This is expensive for
+  # large sets of fixtured data.
+  #
+  # = Dynamic fixtures with ERB
+  #
+  # Some times you don't care about the content of the fixtures as much as you care about the volume.
+  # In these cases, you can mix ERB in with your YAML fixtures to create a bunch of fixtures for load
+  # testing, like:
+  #
+  #   <% 1.upto(1000) do |i| %>
+  #   fix_<%= i %>:
+  #     id: <%= i %>
+  #     name: guy_<%= 1 %>
+  #   <% end %>
+  #
+  # This will create 1000 very simple fixtures.
+  #
+  # Using ERB, you can also inject dynamic values into your fixtures with inserts like
+  # <tt><%= Date.today.strftime("%Y-%m-%d") %></tt>.
+  # This is however a feature to be used with some caution. The point of fixtures are that they're
+  # stable units of predictable sample data. If you feel that you need to inject dynamic values, then
+  # perhaps you should reexamine whether your application is properly testable. Hence, dynamic values
+  # in fixtures are to be considered a code smell.
+  #
+  # = Transactional Fixtures
+  #
+  # Test cases can use begin+rollback to isolate their changes to the database instead of having to
+  # delete+insert for every test case.
+  #
+  #   class FooTest < ActiveSupport::TestCase
+  #     self.use_transactional_fixtures = true
+  #
+  #     test "godzilla" do
+  #       assert !Foo.all.empty?
+  #       Foo.destroy_all
+  #       assert Foo.all.empty?
+  #     end
+  #
+  #     test "godzilla aftermath" do
+  #       assert !Foo.all.empty?
+  #     end
+  #   end
+  #
+  # If you preload your test database with all fixture data (probably in the rake task) and use
+  # transactional fixtures, then you may omit all fixtures declarations in your test cases since
+  # all the data's already there and every case rolls back its changes.
+  #
+  # In order to use instantiated fixtures with preloaded data, set +self.pre_loaded_fixtures+ to
+  # true. This will provide access to fixture data for every table that has been loaded through
+  # fixtures (depending on the value of +use_instantiated_fixtures+).
+  #
+  # When *not* to use transactional fixtures:
+  #
+  # 1. You're testing whether a transaction works correctly. Nested transactions don't commit until
+  #    all parent transactions commit, particularly, the fixtures transaction which is begun in setup
+  #    and rolled back in teardown. Thus, you won't be able to verify
+  #    the results of your transaction until Active Record supports nested transactions or savepoints (in progress).
+  # 2. Your database does not support transactions. Every Active Record database supports transactions except MySQL MyISAM.
+  #    Use InnoDB, MaxDB, or NDB instead.
+  #
+  # = Advanced Fixtures
+  #
+  # Fixtures that don't specify an ID get some extra features:
+  #
+  # * Stable, autogenerated IDs
+  # * Label references for associations (belongs_to, has_one, has_many)
+  # * HABTM associations as inline lists
+  # * Autofilled timestamp columns
+  # * Fixture label interpolation
+  # * Support for YAML defaults
+  #
+  # == Stable, Autogenerated IDs
+  #
+  # Here, have a monkey fixture:
+  #
+  #   george:
+  #     id: 1
+  #     name: George the Monkey
+  #
+  #   reginald:
+  #     id: 2
+  #     name: Reginald the Pirate
+  #
+  # Each of these fixtures has two unique identifiers: one for the database
+  # and one for the humans. Why don't we generate the primary key instead?
+  # Hashing each fixture's label yields a consistent ID:
+  #
+  #   george: # generated id: 503576764
+  #     name: George the Monkey
+  #
+  #   reginald: # generated id: 324201669
+  #     name: Reginald the Pirate
+  #
+  # Active Record looks at the fixture's model class, discovers the correct
+  # primary key, and generates it right before inserting the fixture
+  # into the database.
+  #
+  # The generated ID for a given label is constant, so we can discover
+  # any fixture's ID without loading anything, as long as we know the label.
+  #
+  # == Label references for associations (belongs_to, has_one, has_many)
+  #
+  # Specifying foreign keys in fixtures can be very fragile, not to
+  # mention difficult to read. Since Active Record can figure out the ID of
+  # any fixture from its label, you can specify FK's by label instead of ID.
+  #
+  # === belongs_to
+  #
+  # Let's break out some more monkeys and pirates.
+  #
+  #   ### in pirates.yml
+  #
+  #   reginald:
+  #     id: 1
+  #     name: Reginald the Pirate
+  #     monkey_id: 1
+  #
+  #   ### in monkeys.yml
+  #
+  #   george:
+  #     id: 1
+  #     name: George the Monkey
+  #     pirate_id: 1
+  #
+  # Add a few more monkeys and pirates and break this into multiple files,
+  # and it gets pretty hard to keep track of what's going on. Let's
+  # use labels instead of IDs:
+  #
+  #   ### in pirates.yml
+  #
+  #   reginald:
+  #     name: Reginald the Pirate
+  #     monkey: george
+  #
+  #   ### in monkeys.yml
+  #
+  #   george:
+  #     name: George the Monkey
+  #     pirate: reginald
+  #
+  # Pow! All is made clear. Active Record reflects on the fixture's model class,
+  # finds all the +belongs_to+ associations, and allows you to specify
+  # a target *label* for the *association* (monkey: george) rather than
+  # a target *id* for the *FK* (<tt>monkey_id: 1</tt>).
+  #
+  # ==== Polymorphic belongs_to
+  #
+  # Supporting polymorphic relationships is a little bit more complicated, since
+  # Active Record needs to know what type your association is pointing at. Something
+  # like this should look familiar:
+  #
+  #   ### in fruit.rb
+  #
+  #   belongs_to :eater, :polymorphic => true
+  #
+  #   ### in fruits.yml
+  #
+  #   apple:
+  #     id: 1
+  #     name: apple
+  #     eater_id: 1
+  #     eater_type: Monkey
+  #
+  # Can we do better? You bet!
+  #
+  #   apple:
+  #     eater: george (Monkey)
+  #
+  # Just provide the polymorphic target type and Active Record will take care of the rest.
+  #
+  # === has_and_belongs_to_many
+  #
+  # Time to give our monkey some fruit.
+  #
+  #   ### in monkeys.yml
+  #
+  #   george:
+  #     id: 1
+  #     name: George the Monkey
+  #
+  #   ### in fruits.yml
+  #
+  #   apple:
+  #     id: 1
+  #     name: apple
+  #
+  #   orange:
+  #     id: 2
+  #     name: orange
+  #
+  #   grape:
+  #     id: 3
+  #     name: grape
+  #
+  #   ### in fruits_monkeys.yml
+  #
+  #   apple_george:
+  #     fruit_id: 1
+  #     monkey_id: 1
+  #
+  #   orange_george:
+  #     fruit_id: 2
+  #     monkey_id: 1
+  #
+  #   grape_george:
+  #     fruit_id: 3
+  #     monkey_id: 1
+  #
+  # Let's make the HABTM fixture go away.
+  #
+  #   ### in monkeys.yml
+  #
+  #   george:
+  #     id: 1
+  #     name: George the Monkey
+  #     fruits: apple, orange, grape
+  #
+  #   ### in fruits.yml
+  #
+  #   apple:
+  #     name: apple
+  #
+  #   orange:
+  #     name: orange
+  #
+  #   grape:
+  #     name: grape
+  #
+  # Zap! No more fruits_monkeys.yml file. We've specified the list of fruits
+  # on George's fixture, but we could've just as easily specified a list
+  # of monkeys on each fruit. As with +belongs_to+, Active Record reflects on
+  # the fixture's model class and discovers the +has_and_belongs_to_many+
+  # associations.
+  #
+  # == Autofilled Timestamp Columns
+  #
+  # If your table/model specifies any of Active Record's
+  # standard timestamp columns (+created_at+, +created_on+, +updated_at+, +updated_on+),
+  # they will automatically be set to <tt>Time.now</tt>.
+  #
+  # If you've set specific values, they'll be left alone.
+  #
+  # == Fixture label interpolation
+  #
+  # The label of the current fixture is always available as a column value:
+  #
+  #   geeksomnia:
+  #     name: Geeksomnia's Account
+  #     subdomain: $LABEL
+  #
+  # Also, sometimes (like when porting older join table fixtures) you'll need
+  # to be able to get a hold of the identifier for a given label. ERB
+  # to the rescue:
+  #
+  #   george_reginald:
+  #     monkey_id: <%= ActiveRecord::Fixtures.identify(:reginald) %>
+  #     pirate_id: <%= ActiveRecord::Fixtures.identify(:george) %>
+  #
+  # == Support for YAML defaults
+  #
+  # You probably already know how to use YAML to set and reuse defaults in
+  # your <tt>database.yml</tt> file. You can use the same technique in your fixtures:
+  #
+  #   DEFAULTS: &DEFAULTS
+  #     created_on: <%= 3.weeks.ago.to_s(:db) %>
+  #
+  #   first:
+  #     name: Smurf
+  #     *DEFAULTS
+  #
+  #   second:
+  #     name: Fraggle
+  #     *DEFAULTS
+  #
+  # Any fixture labeled "DEFAULTS" is safely ignored.

+  #
+  # Ensures that each object gets loaded only once by keeping every loaded
+  # object in a map. Looks up objects using the map when referring to them.
+  #
+  # More information on Identity Map pattern:
+  #   http://www.martinfowler.com/eaaCatalog/identityMap.html
+  #
+  # == Configuration
+  #
+  # In order to enable IdentityMap, set <tt>config.active_record.identity_map = true</tt>
+  # in your <tt>config/application.rb</tt> file.
+  #
+  # IdentityMap is disabled by default and still in development (i.e. use it with care).
+  #
+  # == Associations
+  #
+  # Active Record Identity Map does not track associations yet. For example:
+  #
+  #   comment = @post.comments.first
+  #   comment.post = nil
+  #   @post.comments.include?(comment) #=> true
+  #
+  # Ideally, the example above would return false, removing the comment object from the
+  # post association when the association is nullified. This may cause side effects, as
+  # in the situation below, if Identity Map is enabled:
+  #
+  #   Post.has_many :comments, :dependent => :destroy
+  #
+  #   comment = @post.comments.first
+  #   comment.post = nil
+  #   comment.save
+  #   Post.destroy(@post.id)
+  #
+  # Without using Identity Map, the code above will destroy the @post object leaving
+  # the comment object intact. However, once we enable Identity Map, the post loaded
+  # by Post.destroy is exactly the same object as the object @post. As the object @post
+  # still has the comment object in @post.comments, once Identity Map is enabled, the
+  # comment object will be accidently removed.
+  #
+  # This inconsistency is meant to be fixed in future Rails releases.

+  module Locking
+    # == What is Optimistic Locking
+    #
+    # Optimistic locking allows multiple users to access the same record for edits, and assumes a minimum of
+    # conflicts with the data. It does this by checking whether another process has made changes to a record since
+    # it was opened, an <tt>ActiveRecord::StaleObjectError</tt> exception is thrown if that has occurred
+    # and the update is ignored.
+    #
+    # Check out <tt>ActiveRecord::Locking::Pessimistic</tt> for an alternative.
+    #
+    # == Usage
+    #
+    # Active Records support optimistic locking if the field +lock_version+ is present. Each update to the
+    # record increments the +lock_version+ column and the locking facilities ensure that records instantiated twice
+    # will let the last one saved raise a +StaleObjectError+ if the first was also updated. Example:
+    #
+    #   p1 = Person.find(1)
+    #   p2 = Person.find(1)
+    #
+    #   p1.first_name = "Michael"
+    #   p1.save
+    #
+    #   p2.first_name = "should fail"
+    #   p2.save # Raises a ActiveRecord::StaleObjectError
+    #
+    # Optimistic locking will also check for stale data when objects are destroyed. Example:
+    #
+    #   p1 = Person.find(1)
+    #   p2 = Person.find(1)
+    #
+    #   p1.first_name = "Michael"
+    #   p1.save
+    #
+    #   p2.destroy # Raises a ActiveRecord::StaleObjectError
+    #
+    # You're then responsible for dealing with the conflict by rescuing the exception and either rolling back, merging,
+    # or otherwise apply the business logic needed to resolve the conflict.
+    #
+    # This locking mechanism will function inside a single Ruby process. To make it work across all
+    # web requests, the recommended approach is to add +lock_version+ as a hidden field to your form.
+    #
+    # You must ensure that your database schema defaults the +lock_version+ column to 0.
+    #
+    # This behavior can be turned off by setting <tt>ActiveRecord::Base.lock_optimistically = false</tt>.
+    # To override the name of the +lock_version+ column, invoke the <tt>set_locking_column</tt> method.
+    # This method uses the same syntax as <tt>set_table_name</tt>

+  # = Active Record Migrations
+  #
+  # Migrations can manage the evolution of a schema used by several physical
+  # databases. It's a solution to the common problem of adding a field to make
+  # a new feature work in your local database, but being unsure of how to
+  # push that change to other developers and to the production server. With
+  # migrations, you can describe the transformations in self-contained classes
+  # that can be checked into version control systems and executed against
+  # another database that might be one, two, or five versions behind.
+  #
+  # Example of a simple migration:
+  #
+  #   class AddSsl < ActiveRecord::Migration
+  #     def up
+  #       add_column :accounts, :ssl_enabled, :boolean, :default => 1
+  #     end
+  #
+  #     def down
+  #       remove_column :accounts, :ssl_enabled
+  #     end
+  #   end
+  #
+  # This migration will add a boolean flag to the accounts table and remove it
+  # if you're backing out of the migration. It shows how all migrations have
+  # two methods +up+ and +down+ that describes the transformations
+  # required to implement or remove the migration. These methods can consist
+  # of both the migration specific methods like add_column and remove_column,
+  # but may also contain regular Ruby code for generating data needed for the
+  # transformations.
+  #
+  # Example of a more complex migration that also needs to initialize data:
+  #
+  #   class AddSystemSettings < ActiveRecord::Migration
+  #     def up
+  #       create_table :system_settings do |t|
+  #         t.string  :name
+  #         t.string  :label
+  #         t.text    :value
+  #         t.string  :type
+  #         t.integer :position
+  #       end
+  #
+  #       SystemSetting.create  :name => "notice",
+  #                             :label => "Use notice?",
+  #                             :value => 1
+  #     end
+  #
+  #     def down
+  #       drop_table :system_settings
+  #     end
+  #   end
+  #
+  # This migration first adds the system_settings table, then creates the very
+  # first row in it using the Active Record model that relies on the table. It
+  # also uses the more advanced create_table syntax where you can specify a
+  # complete table schema in one block call.
+  #
+  # == Available transformations
+  #
+  # * <tt>create_table(name, options)</tt> Creates a table called +name+ and
+  #   makes the table object available to a block that can then add columns to it,
+  #   following the same format as add_column. See example above. The options hash
+  #   is for fragments like "DEFAULT CHARSET=UTF-8" that are appended to the create
+  #   table definition.
+  # * <tt>drop_table(name)</tt>: Drops the table called +name+.
+  # * <tt>rename_table(old_name, new_name)</tt>: Renames the table called +old_name+
+  #   to +new_name+.
+  # * <tt>add_column(table_name, column_name, type, options)</tt>: Adds a new column
+  #   to the table called +table_name+
+  #   named +column_name+ specified to be one of the following types:
+  #   <tt>:string</tt>, <tt>:text</tt>, <tt>:integer</tt>, <tt>:float</tt>,
+  #   <tt>:decimal</tt>, <tt>:datetime</tt>, <tt>:timestamp</tt>, <tt>:time</tt>,
+  #   <tt>:date</tt>, <tt>:binary</tt>, <tt>:boolean</tt>. A default value can be
+  #   specified by passing an +options+ hash like <tt>{ :default => 11 }</tt>.
+  #   Other options include <tt>:limit</tt> and <tt>:null</tt> (e.g.
+  #   <tt>{ :limit => 50, :null => false }</tt>) -- see
+  #   ActiveRecord::ConnectionAdapters::TableDefinition#column for details.
+  # * <tt>rename_column(table_name, column_name, new_column_name)</tt>: Renames
+  #   a column but keeps the type and content.
+  # * <tt>change_column(table_name, column_name, type, options)</tt>:  Changes
+  #   the column to a different type using the same parameters as add_column.
+  # * <tt>remove_column(table_name, column_names)</tt>: Removes the column listed in
+  #   +column_names+ from the table called +table_name+.
+  # * <tt>add_index(table_name, column_names, options)</tt>: Adds a new index
+  #   with the name of the column. Other options include
+  #   <tt>:name</tt>, <tt>:unique</tt> (e.g.
+  #   <tt>{ :name => "users_name_index", :unique => true }</tt>) and <tt>:order</tt>
+  #   (e.g. { :order => {:name => :desc} }</tt>).
+  # * <tt>remove_index(table_name, :column => column_name)</tt>: Removes the index
+  #   specified by +column_name+.
+  # * <tt>remove_index(table_name, :name => index_name)</tt>: Removes the index
+  #   specified by +index_name+.
+  #
+  # == Irreversible transformations
+  #
+  # Some transformations are destructive in a manner that cannot be reversed.
+  # Migrations of that kind should raise an <tt>ActiveRecord::IrreversibleMigration</tt>
+  # exception in their +down+ method.
+  #
+  # == Running migrations from within Rails
+  #
+  # The Rails package has several tools to help create and apply migrations.
+  #
+  # To generate a new migration, you can use
+  #   rails generate migration MyNewMigration
+  #
+  # where MyNewMigration is the name of your migration. The generator will
+  # create an empty migration file <tt>timestamp_my_new_migration.rb</tt>
+  # in the <tt>db/migrate/</tt> directory where <tt>timestamp</tt> is the
+  # UTC formatted date and time that the migration was generated.
+  #
+  # You may then edit the <tt>up</tt> and <tt>down</tt> methods of
+  # MyNewMigration.
+  #
+  # There is a special syntactic shortcut to generate migrations that add fields to a table.
+  #
+  #   rails generate migration add_fieldname_to_tablename fieldname:string
+  #
+  # This will generate the file <tt>timestamp_add_fieldname_to_tablename</tt>, which will look like this:
+  #   class AddFieldnameToTablename < ActiveRecord::Migration
+  #     def up
+  #       add_column :tablenames, :fieldname, :string
+  #     end
+  #
+  #     def down
+  #       remove_column :tablenames, :fieldname
+  #     end
+  #   end
+  #
+  # To run migrations against the currently configured database, use
+  # <tt>rake db:migrate</tt>. This will update the database by running all of the
+  # pending migrations, creating the <tt>schema_migrations</tt> table
+  # (see "About the schema_migrations table" section below) if missing. It will also
+  # invoke the db:schema:dump task, which will update your db/schema.rb file
+  # to match the structure of your database.
+  #
+  # To roll the database back to a previous migration version, use
+  # <tt>rake db:migrate VERSION=X</tt> where <tt>X</tt> is the version to which
+  # you wish to downgrade. If any of the migrations throw an
+  # <tt>ActiveRecord::IrreversibleMigration</tt> exception, that step will fail and you'll
+  # have some manual work to do.
+  #
+  # == Database support
+  #
+  # Migrations are currently supported in MySQL, PostgreSQL, SQLite,
+  # SQL Server, Sybase, and Oracle (all supported databases except DB2).
+  #
+  # == More examples
+  #
+  # Not all migrations change the schema. Some just fix the data:
+  #
+  #   class RemoveEmptyTags < ActiveRecord::Migration
+  #     def up
+  #       Tag.all.each { |tag| tag.destroy if tag.pages.empty? }
+  #     end
+  #
+  #     def down
+  #       # not much we can do to restore deleted data
+  #       raise ActiveRecord::IrreversibleMigration, "Can't recover the deleted tags"
+  #     end
+  #   end
+  #
+  # Others remove columns when they migrate up instead of down:
+  #
+  #   class RemoveUnnecessaryItemAttributes < ActiveRecord::Migration
+  #     def up
+  #       remove_column :items, :incomplete_items_count
+  #       remove_column :items, :completed_items_count
+  #     end
+  #
+  #     def down
+  #       add_column :items, :incomplete_items_count
+  #       add_column :items, :completed_items_count
+  #     end
+  #   end
+  #
+  # And sometimes you need to do something in SQL not abstracted directly by migrations:
+  #
+  #   class MakeJoinUnique < ActiveRecord::Migration
+  #     def up
+  #       execute "ALTER TABLE `pages_linked_pages` ADD UNIQUE `page_id_linked_page_id` (`page_id`,`linked_page_id`)"
+  #     end
+  #
+  #     def down
+  #       execute "ALTER TABLE `pages_linked_pages` DROP INDEX `page_id_linked_page_id`"
+  #     end
+  #   end
+  #
+  # == Using a model after changing its table
+  #
+  # Sometimes you'll want to add a column in a migration and populate it
+  # immediately after. In that case, you'll need to make a call to
+  # <tt>Base#reset_column_information</tt> in order to ensure that the model has the
+  # latest column data from after the new column was added. Example:
+  #
+  #   class AddPeopleSalary < ActiveRecord::Migration
+  #     def up
+  #       add_column :people, :salary, :integer
+  #       Person.reset_column_information
+  #       Person.all.each do |p|
+  #         p.update_attribute :salary, SalaryCalculator.compute(p)
+  #       end
+  #     end
+  #   end
+  #
+  # == Controlling verbosity
+  #
+  # By default, migrations will describe the actions they are taking, writing
+  # them to the console as they happen, along with benchmarks describing how
+  # long each step took.
+  #
+  # You can quiet them down by setting ActiveRecord::Migration.verbose = false.
+  #
+  # You can also insert your own messages and benchmarks by using the +say_with_time+
+  # method:
+  #
+  #   def up
+  #     ...
+  #     say_with_time "Updating salaries..." do
+  #       Person.all.each do |p|
+  #         p.update_attribute :salary, SalaryCalculator.compute(p)
+  #       end
+  #     end
+  #     ...
+  #   end
+  #
+  # The phrase "Updating salaries..." would then be printed, along with the
+  # benchmark for the block when the block completes.
+  #
+  # == About the schema_migrations table
+  #
+  # Rails versions 2.0 and prior used to create a table called
+  # <tt>schema_info</tt> when using migrations. This table contained the
+  # version of the schema as of the last applied migration.
+  #
+  # Starting with Rails 2.1, the <tt>schema_info</tt> table is
+  # (automatically) replaced by the <tt>schema_migrations</tt> table, which
+  # contains the version numbers of all the migrations applied.
+  #
+  # As a result, it is now possible to add migration files that are numbered
+  # lower than the current schema version: when migrating up, those
+  # never-applied "interleaved" migrations will be automatically applied, and
+  # when migrating down, never-applied "interleaved" migrations will be skipped.
+  #
+  # == Timestamped Migrations
+  #
+  # By default, Rails generates migrations that look like:
+  #
+  #    20080717013526_your_migration_name.rb
+  #
+  # The prefix is a generation timestamp (in UTC).
+  #
+  # If you'd prefer to use numeric prefixes, you can turn timestamped migrations
+  # off by setting:
+  #
+  #    config.active_record.timestamped_migrations = false
+  #
+  # In application.rb.
+  #
+  # == Reversible Migrations
+  #
+  # Starting with Rails 3.1, you will be able to define reversible migrations.
+  # Reversible migrations are migrations that know how to go +down+ for you.
+  # You simply supply the +up+ logic, and the Migration system will figure out
+  # how to execute the down commands for you.
+  #
+  # To define a reversible migration, define the +change+ method in your
+  # migration like this:
+  #
+  #   class TenderloveMigration < ActiveRecord::Migration
+  #     def change
+  #       create_table(:horses) do |t|
+  #         t.column :content, :text
+  #         t.column :remind_at, :datetime
+  #       end
+  #     end
+  #   end
+  #
+  # This migration will create the horses table for you on the way up, and
+  # automatically figure out how to drop the table on the way down.
+  #
+  # Some commands like +remove_column+ cannot be reversed.  If you care to
+  # define how to move up and down in these cases, you should define the +up+
+  # and +down+ methods as before.
+  #
+  # If a command cannot be reversed, an
+  # <tt>ActiveRecord::IrreversibleMigration</tt> exception will be raised when
+  # the migration is moving down.
+  #
+  # For a list of commands that are reversible, please see
+  # <tt>ActiveRecord::Migration::CommandRecorder</tt>.
