I'm still a little bit confused, but here's what I'd suggest: In the model you've described you can say something like: BB.objects.filter(ab__aa__name="aa") to get the list of BB objects that are mapped to that specific AA object. In addition - if you don't have other fields in the AB model, substitute that with a M2M field in one of the AA or BB models. It will allow you to use the full M2M relationship syntax in your QuerySets. Finally - those model names are giving us headaches. Sometimes it helps a lof if you ask your questions in the context of your system and people might have more clues and ideas for you. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
