Django - AttributeError: объект 'tuple' не имеет атрибута 'name'

Я пытаюсь сделать сайт электронной коммерции, где "AnonymousUser" или гостевой пользователь может заказывать и проверять товары без необходимости входа или создания учетной записи.

Я хочу сделать так, чтобы имя и email, которые были введены в форме оформления заказа, попадали в базу данных. Но в таблице Customer всегда возвращается пусто. А после совершения платежа возникла ошибка, которая гласит AttributeError: 'tuple' object has no attribute 'name'

Вот полный отслеживание в Terminal:

    Internal Server Error: /process_order/
    Traceback (most recent call last):
      File "C:\Users\RolfShin025\Desktop\E-COMMERCE\env\lib\site-packages\django\core\handlers\exception.py", line 47, in inner
        response = get_response(request)
      File "C:\Users\RolfShin025\Desktop\E-COMMERCE\env\lib\site-packages\django\core\handlers\base.py", line 181, in _get_response
        response = wrapped_callback(request, *callback_args, **callback_kwargs)
      File "C:\Users\RolfShin025\Desktop\E-COMMERCE\WannaCome\store\views.py", line 82, in processOrder
        customer.name = name
    AttributeError: 'tuple' object has no attribute 'name'

I also have some error in the console that says: `POST http://127.0.0.1:8000/process_order/ 500 (Internal Server Error)` and `Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0`

Вот мой файл models.py:

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

# Create your models here.

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)

    def __str__(self):
        return self.name

class Product(models.Model):
    name = models.CharField(max_length=200)
    price = models.DecimalField(max_digits=9, decimal_places=2)
    digital = models.BooleanField(default=False, null=True, blank=True)
    image = models.ImageField(null=True, blank=True)

    def __str__(self):
        return self.name

    @property
    def imageURL(self):
        try:
            url = self.image.url

        return url

class Order(models.Model):
    customer = models.ForeignKey(Customer, on_delete=models.CASCADE, null=True, blank=True)
    date_ordered = models.DateTimeField(auto_now_add=True)

    transaction_id = models.CharField(max_length=20, null=True)

    def __str__(self):
        return str(self.id)

    @property
    def shipping(self):
        shipping = False
        orderitems = self.orderitem_set.all()
        for i in orderitems:
            if i.product.digital == False:
                shipping = True
        return shipping

    @property
    def get_cart_total(self):

        total = sum([item.get_total for item in orderitems])
        return total

    @property

    @property
    def get_total(self):
        total = self.product.price * self.quantity
        return total

class ShippingAddress(models.Model):
    customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, null=True)
    order = models.ForeignKey(Order, on_delete=models.SET_NULL, null=True)
    address = models.CharField(max_length=200, null=False)
    city = models.CharField(max_length=200, null=False)
    state = models.CharField(max_length=200, null=False)
    zip = models.CharField(max_length=200, null=False)
    date_added = models.DateTimeField(auto_now_add=True)

Вот мой views.py:

Вот мой файл utils.py:

import json
from .models import *

def cookieCart(request):
    try:
        cart = json.loads(request.COOKIES['cart'])
    except:
        cart = {}
    
    print('Cart:', cart)
    items = []
    order = {'get_cart_total':0, 'get_cart_items':0, 'shipping': False}
    cartItems = order['get_cart_items']

    for i in cart:
        try:
            cartItems += cart[i]["quantity"]

            product = Product.objects.get(id=i)
            total = (product.price * cart[i]['quantity'])

            order['get_cart_total'] += total
            order['get_cart_items'] += cart[i]['quantity']

            item = {
                'product':{
                    'id':product.id,
                    'name':product.name,
                    'price':product.price,
                    'imageURL':product.imageURL,
                    },
                'quantity': cart[i]['quantity'],
                'get_total': total,
                }
            items.append(item)

            if product.digital == False:
                order['shipping'] = True

        except:
            pass
    return {'cartItems': cartItems, 'order': order, 'items': items}

def cartData(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()
        cartItems = order.get_cart_items

    else:
        cookieData = cookieCart(request)
        cartItems = cookieData['cartItems']
        order = cookieData['order']
        items = cookieData['items']

    return {'cartItems': cartItems, 'order': order, 'items': items}

А вот мой файл checkout.html:

    customer,created = Customer.objects.get_or_create(
        email=email,
        )
    if not created:
        customer.name = name
        customer.save()
