A checklist has many task_status, I have displayed the view in nested model atttributes form, checklist_instance attributes and its associated nested attributes are getting updated correctly. while i try to update user information to the checklist instance, the following updates only if the updated_by_user is not same as @authenticated_user. def update @checklist_instance.attributes = params[:checklist_instance] @checklist_instance.updated_by_user = @authenticated_user if @checklist_instance.save flash[:notice] = ''Checklist was successfully updated.'' redirect_to_edit end end Could anyone suggest me a solution for this.. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
