+module ActiveModel
+
+ # == Active Model Basic Model
+ #
+ # Includes the required interface for an object to interact with +ActionPack+,
+ # using different +ActiveModel+ modules. It includes model name introspections,
+ # conversions, translations and validations. Besides that, it allows you to
+ # initialize the object with a hash of attributes, pretty much like
+ # +ActiveRecord+ does.
+ #
+ # A minimal implementation could be:
+ #
+ # class Person
+ # include ActiveModel::Model
+ # attr_accessor :name, :age
+ # end
+ #
+ # person = Person.new(:name => 'bob', :age => '18')
+ # person.name # => 'bob'
+ # person.age # => 18
+ #
+ # Note that, by default, +ActiveModel::Model+ implements +persisted?+ to
+ # return +false+, which is the most common case. You may want to override it
+ # in your class to simulate a different scenario:
+ #
+ # class Person
+ # include ActiveModel::Model
+ # attr_accessor :id, :name
+ #
+ # def persisted?
+ # self.id == 1
+ # end
+ # end
+ #
+ # person = Person.new(:id => 1, :name => 'bob')
+ # person.persisted? # => true
+ #
+ # Also, if for some reason you need to run code on +initialize+, make sure you
+ # call super if you want the attributes hash initialization to happen.
+ #
+ # class Person
+ # include ActiveModel::Model
+ # attr_accessor :id, :name, :omg
+ #
+ # def initialize(attributes)
+ # super
+ # @omg ||= true
+ # end
+ # end
+ #
+ # person = Person.new(:id => 1, :name => 'bob')
+ # person.omg # => true
+ #
+ # For more detailed information on other functionalities available, please refer
+ # to the specific modules included in +ActiveModel::Model+ (see below).
