我想知道如何由创建它的用户实际更新on对象

Question

我想知道如何更新由User（hunter）创建的对象。这是以下产品的型号：

class Product(models.Model):
    title = models.CharField(max_length=250)
    pub_date = models.DateTimeField()
    body = models.TextField()
    image = models.ImageField(upload_to='images/')
    icon = models.ImageField(upload_to='images/')
    url = models.TextField()
    hunter = models.ForeignKey(User, on_delete=models.CASCADE)

以下是用于创建对象的创建方法：

def create(request):
  if request.method == 'POST':
    if request.POST['title'] and request.POST['body'] and request.POST['url'] and request.FILES['icon'] and request.FILES['image']:
      product = Product()
      product.title = request.POST['title']
      product.body = request.POST['body']
      if request.POST['url'].startswith('http://') or request.POST['url'].startswith('https://'):
        product.url = request.POST['url']
      else:
        product.url = 'http://' + request.POST['url']
      product.icon = request.FILES['icon']
      product.image = request.FILES['image']
      product.pub_date = timezone.datetime.now()
      product.hunter = request.user
      product.save()
      return redirect('/products/' + str(product.id))

能否请您帮我创建一个更新方法，以便只有创建此产品的用户才能删除它？
