Congratulations on solving your problem. However, I just want to clarify one thing regarding named routes. (Just to help users reading the thread)
What Hendra said isn't wrong. You can pass anything to part_url and it will be passed to the controller as params[:id]. To make our codes easier to read, the core developers allowed us to pass an object to part_url. Someone correct me if I'm wrong, but I believe passing an object to part_url uses the object's to_param method which returns the id by default. So part_url(@part) and part_url(@part.id) should return the same string if you didn't override @part's to_param method.
