Привет, я пытаюсь создать сайт покупок в Интернете, но когда я добавляю товары (дома) в корзину, я получаю следующую ошибку 

    Internal Server Error: /cart/

У меня есть приложение для магазина и корзины.соответствующие представления /cart/view.py

@require_POST
def cart_add(request, house_id):
    cart = Cart(request)
    house = get_object_or_404(House, id=house_id)
    form = CartAddHouseForm(request.POST)
    if form.is_valid():
        cd = form.cleaned_data
        cart.add(house=house,
                 quantity=cd['quantity'],
                 update_quantity=cd['update'])
    return redirect('cart:cart_detail')

def cart_remove(request, house_id):
    cart = Cart(request)
    house = get_object_or_404(House, id=house_id)
    cart.remove(house)
    return redirect('cart:cart_detail')

def cart_detail(request):
    cart = Cart(request)
    for item in cart:
        item['update_quantity_form'] = CartAddHouseForm(
                          initial={'quantity': item['quantity'],
                          'update': True})
    return render(request, 'cart/detail.html', {'cart': cart})

/ shop / views.py 

def house_list(request, category_slug=None):
    category = None
    categories = Category.objects.all()
    houses = House.objects.filter(available=True)
    if category_slug:
        category = get_object_or_404(Category, slug=category_slug)
        houses = houses.filter(category=category)
    return render(request,
                  'shop/house/list.html',
                  {'category': category,
                   'categories': categories,
                   'houses': houses})

def house_detail(request, id, slug):
    house = get_object_or_404(House,
                            id=id,
                            slug=slug,
                            available=True)
    cart_house_form = CartAddHouseForm()
    return render(request,
                'shop/house/detail.html',
                {'house': house,
                'cart_house_form':cart_house_form})

Вот urls.py для приложения корзины 

urlpatterns = [
    path('', views.cart_detail, name='cart_detail'),
    path('add/<int:house_id>/',
         views.cart_add,
         name='cart_add'),
    path('remove/<int:house_id>/',
         views.cart_remove,
         name='cart_remove'),
]

Urls.py для моего проекта 

urlpatterns = [
    path('admin/', admin.site.urls),
    path('cart/', include('cart.urls', namespace='cart')),
    # path('orders/', include('orders.urls', namespace='orders')),
    path('', include('shop.urls', namespace='shop')),
]

Шаблон, в котором возникает ошибка /templates/shop/base.html

Я все еще изучаю Django, любая помощь будет признательна

Попробуйте изменить свой URL-адрес на это: 

re_path(add/(?P<house_id>[0-9]+)/$',view.cart_add)
