I would always, as a first solution, look at what the question being asked is. You want to know if 'a given user has a valid membership', therefore use the User has_many memberships option, I would not try to turn the question on it's head to answer it. > So my idea is to add a redundant user_id to membership, and to set an > expires_at for a membership only when the order gets paid.
