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).
