NoReverseMatch 오류는 어떻게 처리합니까?

Question

처음으로 이러한 오류가 발생하고 주변을 둘러 보았지만 동일한 상황에서 오류가 발생하지 않았습니다. 사용자가 양식을 제출하면 리디렉션이 발생합니다.

제 생각에는 reverse() 함수를 사용하여 url을 반환하고 리디렉션합니다. 여기 이다의 의견이다 : 여기

def get_category(request): 
    categories = Category.objects.all().prefetch_related('item') 
    form = ItemAddToCartForm(request=request, label_suffix=':') 
    # need to evaluate the HTTP method 
    if request.method == 'POST': 
     # add to order..create the bound form 
     postdata = request.POST.copy() 
     form = ItemAddToCartForm(request,postdata) 
     # check validation of posted data 
     if form.is_valid(): 
      # add to order and redirect to order page 
      order.add_to_order(request) 
      # if test cookie worked, get rid of it 
      if request.session.test_cookie_worked(): 
       request.session.delete_test_cookie() 
      url =urlresolvers.reverse('show_order') 
      # redirect to order page 
      return HttpResponseRedirect(url) 
    else: 
     # it's a GET, create the unbound from. Note request as a Kwarg 
     form = ItemAddToCartForm(request=request,label_suffix=':') 
    # assign the hidden input the item slug 
    # set the test cookie on our first GET request 
    request.session.set_test_cookie() 
    context={ 
     'categories':categories, 
     'form':form, 
#  'menu':menu, 

    } 
    return render_to_response('category.html',context,context_instance=RequestContext(request)) 

그것을 지시하는 URL의 도면에 :

from django.conf.urls.defaults import * 

urlpatterns = patterns(
    'live.views', 
    url(r'^$', view="show_order",name="order_index"), 
) 

: 상기 뷰

def show_order(request): 
    if request.method == 'POST': 
     if postdata['submit'] == 'Remove': 
      order.remove_from_order(request) 
     if postdata['submit'] == 'Update': 
      order.update_order(request) 
    order_items = order.get_order_items(request) 
    page_title = 'F4L order' 
    order_subtotal = order.order_subtotal(request) 
    return render_to_response('public/order.html',context_instance=RequestContext(request)) 

URL을 두보기의 URL :

<form method="post" action="."> 
    <a href="{% url order_index %}"> 
    {% csrf_token %} 
    {{ form.as_p }} 
    <br /> 
    <input type="submit" value="Add To Order" name="submit"> 
    </a>

감사합니다 : 여기

url(r'^orders/', include('live.urls')), 
url(r'^menu/$','live.views.get_category'), 

(210)의 형식은 HTML입니다.

역방향으로 전달 된 값은보기가 아닌 URL의 이름이어야합니다.

url =urlresolvers.reverse('order_index')
