Всем привет! После того как добавил на сайт регистрацию стала появляться ошибка при добавлении товара в корзину
IntegrityError at /add-to-cart/Interior_paints1/
NOT NULL constraint failed: mainapp_cartproduct.user_id
Ошибка появляется именно если пользователь не авторизован на сайте, если авторизоваться, то ошибка сразу же пропадает.

Объясните пожалуйста, как мне сделать, чтобы можно было добавлять товар в корзину анонимный юзерам.
