/shop/process_payment/ 处的 FieldError 无法将关键字 'id' 解析为字段。选项包括：地址、金额、电子邮件、items_json、姓名、order_id、phone

Question

我正在使用 Django 2.1.5 和 Python 3.5

我想将 paypal 支付网关集成添加到我的项目中，但我遇到这个问题无法将关键字 'id' 解析为字段。选择是：地址，金额等

def 结帐（请求）：

if request.method == "POST":

    items_json = request.POST.get('itemsjson', '')
    name     = request.POST.get('name', '')
    amount     = request.POST.get('amount', '')
    email    = request.POST.get('email', '')
    address  = request.POST.get('address1', '') + " " + request.POST.get('address2', '')
    city     = request.POST.get('city', '')
    state    = request.POST.get('state', '')
    zip_code = request.POST.get('zip_code', '')
    phone    = request.POST.get('phone', '')
    order = Orders(items_json=items_json, name=name, amount=amount, email=email, address=address, city=city, state=state, zip_code=zip_code, phone=phone)
    order.save()
    update = OrderUpdate(order_id=order.order_id, update_desc="The order has been placed")
    update.save()
    thank = True
    id = order.order_id
    return redirect('process_payment')
return render(request, 'shop/checkout.html', locals())

def process_payment（请求）：

order_id = request.session.get('order.order_id')
order = get_object_or_404(Orders, id=order_id)
host = request.get_host()

paypal_dict = {
    'business': settings.PAYPAL_RECEIVER_EMAIL,
    'amount': str(amount),
    'item_name': name,
    'invoice': str(order.order_id),
    'currency_code': 'USD',
    "notify_url": request.build_absolute_uri(reverse('paypal-ipn')),
    "return": request.build_absolute_uri(reverse('payment_done')),
    "cancel_return": request.build_absolute_uri(reverse('payment_cancelled')),

}

form = PayPalPaymentsForm(initial=paypal_dict)
context = {"form": form}
return render(request, "shop/process_payment.html", context)

我的models.py文件

class 订单(models.Model):

order_id   = models.AutoField(primary_key=True)
items_json = models.CharField(max_length=5000)
amount     = models.IntegerField(default=0)
name       = models.CharField(max_length=90)
email      = models.CharField(max_length=120)
address    = models.CharField(max_length=120)
city       = models.CharField(max_length=120)
state      = models.CharField(max_length=120)
zip_code   = models.CharField(max_length=120)
phone      = models.CharField(max_length=120)

class 订单更新（models.Model）：

update_id  = models.AutoField(primary_key=True)
order_id   = models.IntegerField(default="")
update_desc = models.CharField(max_length=5000)
timestamp   = models.DateField(auto_now_add=True)

如果您的订单模型的主键字段不是 id ，请使用 pk :

order = get_object_or_404(Orders, pk=order_id)

/shop/process_payment/ 处的 FieldError 无法将关键字 'id' 解析为字段。选项包括：地址、金额、电子邮件、items_json、姓名、order_id、phone

FieldError at /shop/process_payment/ Cannot resolve keyword 'id' into field. Choices are: address, amount, email, items_json, name, order_id, phone
