Моя страница входа и регистрации не работает, когда я нажимаю кнопку, и моя конфигурация URL-адреса хорошая ⇐ Python

[Anonymous]

Я создаю проект django и постоянно получаю эту ошибку: - django.db.utils.IntegrityError: нулевое значение в столбце «id» отношения «проверка» нарушает ненулевое ограничение
DETAIL: неверная строка содержит (null, 7, 839510, 0, 2024-10-29 19:51:34.057435+00, f, null).
Я думаю, это как-то связано с моей базой данных, я использую pgadmin
