I don't understand precisely what you mean, but two of the arguments
to generic_inlineformset_factory() are 'form' and 'formset', allowing
you to specify a different class for the form objects created, and a
different base class for the formset created. This is generally true
for all formset_factory() functions.

This allows you almost unlimited flexibility in controlling how the
forms are generated, how they behave and so forth. Eg, if I wanted the
formset to take an additional argument on construction, and set that
argument on each instance the formset creates/modifies, I could do
something like this:


class TeamBaseFormset(BaseModelFormSet):
def __init__(self, *args, **kwargs):
self.manager = kwargs.pop('manager')
def save(self, commit=True, *args, **kwargs):
instances = super(TeamBaseFormset, self).save(commit=False,
*args, **kwargs)
for team in instances:
team.manager = self.manager
if commit:
team.save()
return instances

TeamFormset = modelformset_factory(Team, formset=TeamBaseFormset)

form = TeamFormset(manager=manager)

Since you have control over the formset class and the form, you can
override or change any behaviour that you want.
