Django мультимодельформ + Inlineformset + updateview

Question

У меня проблема с обработкой Updateview в django. Мой дизайн содержит 2 модели и один Inlineformset. Это представление будет добавлено с большим количеством моделей и наборов inlineform, если это работает.

Мой createview работает нормально. Но Updateview выдает прикрепленную ошибку error image . Любая идея, почему это вызывает. Любой лучший способ работы с несколькими формами и несколькими встроенными формами.

Формы
