Something like instance_of_model.many.add(another_instance.many.all()) might work. > If I have two instances of OtherModel, how do construct a queryset that > matches all instances of Model that reference both? I think, but I am not sure, that you should do two chained .filter() calls. Something like: qs.filter(many__pk=other_instance1.pk).filter(many__pk=other_instance2.pk). No guarantees of that doing anything sane :) - Anssi -- You received this message because you are subscribed to the Google Groups "Django users" group.
