Dirty object with nested attributes

hi,

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

end

end

class Address < ActiveRecord::Base

belongs_to :addressee, :polymorphic => true

end
