Я пытаюсь создать веб-сайт электронной коммерции, и когда я работаю над заказом корзины для пользователей, не прошедших проверку подлинности, а затем сохраняю его и отправляю на серверную часть, я просто получаю эту ошибку при каждом просмотре, когда я вхожу в панель администратора django.

Это хорошо работает, когда я не зарегистрирован как администратор, хотя он не сохраняет заказ после того, как заказ будет завершен.

Ошибка в том, что объект «Нетип» не может быть подписан.

и упоминает эту переменную как пустую:

Карты = данные[‘Карты’]
