I think I misunderstood your first post, sorry. I tried to use
formset_factory with my ModelForm based form :
FormSet = formset_factory(SomeModelForm, extra=0)
forms = FormSet(initial=[{"field": 1}, {"field": 2}, {"field": 3}])
It works (I thought you _had_ to use modelformset_factory to create
ModelForm formsets). But then again, I get INITIAL_FORMS=3 in the
output. If I set extra to 3, I still get INITIAL_FORMS=3, and 3
additional blank forms, there seems to be no way to populate the extra
forms with initial data.
So I think a new keyword argument is needed for formset_factory to
solve this particular issue, perhaps extra_initial ?
