The issue here is not the presence or absence of a join model -- after all, for a simple habtm, there's no reason at all to introduce the extra class. Rather, this is a reflection of the fact that the OP is trying to do something weird. With or without a join model, there should be no reason to add b to a.bs 3 times. To the OP: can you explain more about why you think you need this? I'm guessing your DB setup may be a bit pathological. > > > -- > Greg Donald > http://destiney.com/ Best, -- Marnen Laibow-Koser http://www.marnen.org [email protected] -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
