Python 使用选择框在Django UpdateView中显示产品实例

我需要在选择框中显示产品实例。我非常确定我很好地遵循了get_对象和get_初始方法，但是表单似乎没有使用我想要更新的产品启动。还有别的办法吗

型号：

class Order(models.Model):
    
    options = (

        ('Pending', 'Pending'),
        ('Out for delivery', 'Out for delivery'),
        ('Delivered', 'Delivered'),
    )

    customer = models.ForeignKey(Customer, on_delete=models.CASCADE)
    product = models.ForeignKey(Product, on_delete=models.CASCADE)
    date_created = models.DateTimeField(auto_now_add=True)
    status = models.CharField(choices=options, null=True, max_length=200)

    def __str__(self):
        return self.status

    class Meta:
        ordering = ['-date_created']

我的看法是：

class OrderUpdateView(UpdateView):
    
    model = Order
    form_class = OrderUpdateForm
    template_name = 'crmapp/update-order.html'
    context_object_name = 'order'
    success_url = '/'

    def get_initial(self):
        initial = super(OrderUpdateView, self).get_initial()

        content = self.get_object()
        initial['customer'] = content.customer
        initial['product'] = content.product
        initial['status'] = content.status

        return initial

    def get_object(self, *args, **kwargs):
        product = get_object_or_404(Order, pk=self.kwargs['pk'])
        return product

网址：

 path('update-order/<str:pk>/', OrderUpdateView.as_view(), name='update-order')

path（'update-order/'，OrderUpdateView.as_view（），name='update-order'）
