I suspect the right way is to simply use "has_many :through" _instead_ of the habtm relationship. If you're needing to get through to the other side, you can (probably) do that, too -- at least, I remember this working, the last time I tried: has_many :foos has_many :bars, :through => :foos has_many :others, :through => :bars It's been awhile, though, so I'm not sure.
