Django UpdateView Два отдельных сохранения формы (включена inlineformset_factory)

У меня есть конкретная проблема с моими формами. Я думаю, будет лучше поделиться своими кодами вместо того, чтобы подробно объяснять проблему.

Вкратце объясню: внутри моей модели есть поле OneToOneField и модель этого поля имеет форму inlineformset_factory. Моя новая модель также имеет форму, и я хочу сохранить обе формы.

Когда я хочу сохранить форму обновления предложения, я получаю следующую ошибку:

TypeError at /ru/mytarget/offer-update/T2GTTT053E9/

AdminOfferUpdateView.form_invalid() отсутствуют 2 обязательных позиционных аргумента: 'request_form' и 'request_item_formset'
