- What's this?
Active Model Basic Model
Allows implementing models similar to ActiveRecord::Base. Includes ActiveModel::API 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 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).
