Это мой models.py

from django.db import models
from django.contrib.auth.models import AbstractUser,User


class Customer(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True)
    name =  models.CharField(max_length=200, null=True)
    email = models.CharField(max_length=200, null=True)
    
    def __str__(self):
        return self.name

Это мой views.py

@login_required
def add_cart(request):
    if request.user.is_authenticated :
        customer = request.user.customer
        order,created = Order.objects.get_or_create(customer=customer, complete=False)
        items = order.orderitem_set.all()
    else:
        item = []
        
    context = {'items':items}
    return render(request,'store/cart.html', context)

Это мой forms.py

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User


# Create your forms here.

class NewUserForm(UserCreationForm):
    email = forms.EmailField()
    

    class Meta:
        model = User
        fields = ("username", "email", "password1", "password2")

я нахожу способ заставить функцию корзины работать, но не могу понять в чем проблема, я использую систему аутентификации django с AbsractUser и пытаюсь сопоставить это с моделью клиента. может ли кто-нибудь помочь ....?
