The attached patch allows definitions like this: {{{ class AuthorForm(forms.ModelForm): class Meta: model = Author class DeclarativeAuthorFormSet(forms.models.ModelFormSet): form = AuthorForm model = Author extra = 3 }}} and {{{ class BookForm(forms.ModelForm): class Meta: model = Book class DeclarativeAuthorBooksFormSet(forms.models.InlineFormSet): model = Book form = BookForm parent = 'author' }}} An advantage is that the defined form is directly used as the form class in the formset, not as a base class for a new form class (what inlineformset_factory does). This way specific field definitions and other customisations in the form work like they should so you don't need to redefine things in __init__().
