updated? method in Rails3.1

Question

I am upgrading a rails3.0 app to rails3.1.10 I have model

class User < ActiveRecord::Base
belongs_to :account

.....

def some_method
  return unless self.account.updated?
  .......
end

end

but .updated? method seems to be removed from Rails3.1.10 Is there any alternatives to it? What I need is to track if parent object was changed

thanks

I think you can use the method changed? which is a part of ActiveModel::Dirty.

EDIT:

If you want to track a record change after saving you can try the TrackIt gem which provides exactly the functionality you would like to have.

I tried changed? but it seems not to work as expected. Maybe I have missed something deeper in logic of the app – user1136228 Feb 17 '13 at 16:45
How do you expect it to behave? – Erez Rabih Feb 17 '13 at 17:11
I know than changed? work like this `user = User.first user.name "name" user.changed? # => false user.name = "changed" user.changed? # => true user.save user.changed? # => false` thanks for help – user1136228 Feb 17 '13 at 19:14
Edited my answer to suit your needs. – Erez Rabih Feb 17 '13 at 19:41
Thanks. So the behavior of updated? and changed? are the same. But it is not true in my app. – user1136228 Feb 18 '13 at 10:39
