django 2.0 url.py включает namespace = "xyz"

Question

У меня проблема с маршрутизацией django.conf.urls include () - основная папка проекта - urls.py

Строка 22 urls.py (pip freeze и urls.py - см. Ниже) выдает ошибку в консоли:

Quit the server with CONTROL-C.

Я уже пробовал определить переменную app_name = в urls.py, как предлагается здесь Как зарегистрировать шаблоны URL-адресов маршрутизатора DRF в django 2. Проблема возникла после переноса с Django 1.11 на 2.0. Есть ли лучший способ, кроме вызова представления, путем определения name = "yournametothedetailview" непосредственно из проекта urls.py.

Большое спасибо, лучший Эрнст!

Answer 1

На всякий случай, если вы обновили более старую версию Django, было бы желательно, если вы зайдете в конкретный файл приложения urls.py и добавите следующую строку прямо над шаблонами URL-адресов;

app_name = 'current_app_name'

Ниже приведен пример того, как это будет выглядеть;

app_name = 'current_app_name'

urlpatterns = [
     url(r'^$', views.index, name='index'),
]

Answer 2

Я думаю, чтобы иметь возможность ссылаться на пространство имен → в вашем urls.py приложения композиции, вы должны установить переменную app_name = 'your app name'
