Hi, I want to make a copy of an object with its associations, and I am looking for an elegant solution.

Seth, It really depends how often you do that check. If it happens only once or twice in your whole application, that''s just fine. If it happens more than that and in multiple controllers/views then maybe you want to create a helper for it.
