You need to define a new base formset and form classes that take the
additional arguments when constructing form/formset, and to supply
them when the formset creates the forms, and supply these classes as
arguments to inlineformset_factory.

Eg, to accept an argument of 'profile' on each form:

from django.form.models import BaseInlineFormSet

class MyForm(Form):
def __init__(self, *args, **kwargs):
self.profile = kwargs.pop('profile')

class MyFormBaseFormSet(BaseInlineFormSet):
def __init__(self, profile=None, *args, **kwargs):
self.profile = profile
def _construct_form(self, i, **kwargs):
kwargs['profile'] = self.profile
return super(MyFormBaseFormSet, self)._construct_form(i, **kwargs)

MyFormSet = inlineformset_factory(MyModel, form=MyForm,
formset=MyFormBaseFormSet)

Cheers
