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
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
