I have been struggling with this same problem and found little help with using prepare(). I will share my solution although I am still hoping that a more efficient method exists. I am using version 0.95
In my custom manipulator.save() ------------------------------- temp = form_fields(..all the none checkbox fields..) temp.save() for n in range(1, my_model.objects.count()): if new_data.has_key('checkbox_fieldname'+str(n)): temp.checkbox_fieldname.add(my_model.objects.get(pk=n)) I have tested this only for an addmanipulator, but it works. Hopes this helps --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
