Django Форма с зависимыми формами ForeignKey на одной странице

Добрый день, я пытаюсь реализовать django с зависимыми foreignkey формами на одной странице. У меня есть три moodel Store, Product и ProductClothing. Все они связаны с ForeignKey соответственно. Пользователи создают свой магазин отдельно и перенаправляются на страницу детализации магазина, где им нужно загрузить продукты. Но на этот раз я хочу, чтобы они загружали сразу и продукты, и одежду. Ниже приведены мои models.py и views.py того, что я имею в настоящее время на странице детального просмотра магазина. Также я получаю следующую ошибку:

error.py
NOT NULL constraint failed: product_productclothing.product_id
