You need to understand the level of abstraction here. Of course the
API can be improved to provide a way to pass custom parameters to the
forms, but certainly that would seem prohibiting and people will
eventually need to override something.
It is basic Python OO at this point. Subclass _construct_form and call
the parent method. The signature of _construct_form allows you to pass
your own keyword arguments to the form in which case this is what you
would do with your two arguments.
class MyBaseFormSet(BaseFormSet):
def _construct_form(self, i, **kwargs):
kwargs["my_own_argument"] = "my value"
return super(MyBaseFormSet, self)._construct_form(i, **kwargs)
