If you look at the source code for update_attributes, you'll see it does a "save" in the method, so once it's finished, the are no changed fields (because the record has already been updated). You need a callback filter to run in your User model; and "before_save" seems sensible to me: def before_save send_mail if self.changed? end -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
