Я использую Django REST Framework, я застрял во вставке связанных данных о продукте в несколько таблиц. Пожалуйста, ознакомьтесь со сценарием ниже:

В AddProductSerializer , я хочу снова вставить цикл variations for в часть else во вложенном сериализаторе django, чтобы я мог сохранить все данные, связанные с таблицей продуктов.

Данные Json
