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).
