module ActiveModel
  # == Active \Model \Basic \Model
  #
  # Allows implementing models similar to <tt>ActiveRecord::Base</tt>.
  # Includes <tt>ActiveModel::API</tt> for the required interface for an
  # object to interact with Action Pack and Action View, but can be
  # extended with other functionalities.
  #
  # 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"
  #
  # If for some reason you need to run code on <tt>initialize</tt>, 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 <tt>ActiveModel::Model</tt>
  # (see below).
