У меня есть проблема для анонимных пользователей, когда анонимный пользователь нажимает на добавление элементов корзины, не добавляясь в корзину < /p>
Моя клиентская модель: < /p>
class Customer(models.Model) :
user = models.OneToOneField(User,on_delete=models.CASCADE,null=True, blank=True)
customer_name= models.CharField(max_length=50, null=True) customer_email = models.CharField(max_length=100, null=True)
