I want to use dirty object with nested attributes here is my example.
i have form having user and addresses field when i am editing user and after updating user inside user model i am checking for any field from user get dirty using @self.changed? method it giving me proper output in this i am doing @self.address.changed?( I Have polymorphic association in user and addresses) but it is giving me nil/false if address is changed but if i am putting @self.changed? in address model it is giving me proper output.
Please anybody explain me how to use dirty object concept with model association or with nested attributes?
class User < ActiveRecord::Base
has_many :addresses, :as =>:addressee, :dependent => :destroy accepts_nested_attributes_for :addresses, :allow_destroy => true after_update :send_account_updated_email
def send_account_updated_email self.changed //giving correct changed field name self.addresses.changed //not working self.addresses.first.changed // not working
class Address < ActiveRecord::Base
belongs_to :addressee, :polymorphic => true
