modelformset_factory(AdrecaProjecteAutoocupat, form=FormulariAdrecaProjecteAutoocupat, can_delete=True) if i setup "extra=0", it doesn't complain anymore but it doesn't show any form. my intention is to create different AdrecaProjecteAutoocupat instances via this model formset. but it seems that if there is no instances on the queryset it raise a key error when asking for extra forms. every kind of help would be really appreciated. thx. -- You received this message because you are subscribed to the Google Groups "Django users" group.
