当我要从购物车中删除产品时，我没有得到任何回应?

Question

这是我的观点。

def remove_from_cart(request,id):
try:
the_id = request.session['cart_id']
cart = Cart.objects.get(id=the_id)
print(cart)
except:
return HttpResponseRedirect(reverse('cart'))
cartitem=CartItem.objects.get(id=id)
cartitem.delete()
cartitem.cart=None
cartitem.save()

这是我的网址映射

url('^cart/(?P<id>d+)/$',views.remove_from_cart,name='remove_from_cart'),
<a href="{% url 'remove_from_cart' item.id %}">Remove</a>

我在我的终端上收到这个

"GET/cart/3/HTTP/1.1" 302 0

Answer 1

你必须从viewreturnHttpResponse。

from  django.http.response import HttpResponse
def remove_from_cart(request,id):
try:
the_id = request.session['cart_id']
cart = Cart.objects.get(id=the_id)
print(cart)
except:
return HttpResponseRedirect(reverse('cart'))
cartitem=CartItem.objects.get(id=id)
cartitem.delete()
cartitem.cart=None
cartitem.save()
# Always return a response
return HttpResponse('saved')
