update parent in assocation callback

rubyonrails-talk

I'd like to update an attribute on the parent using an association callback. For example

class User < ActiveRecord::Base   has_many :peeps, :after_add => :update_latest_peep

  protected     def update_latest_peep(peep)       self.latest_peed_id= peep.id     end end

If I debug and step through the code, I see that @owner (which is the user in question) actually does have that attribute set however when the code exists, it doesn't seem to save.

Thanks.
