Django 2.0 'name' is not a registered namespace

Question

I\'ve seen this error posted several times, but I can\'t find anyone using Django 2.0 and having the problem.

The problem cropped up when I tried to nest one app inside

Answer 1

There are two ways can hanlded this.

Firstly,you can set an app_name attribute in the included URLconf module, at the same level as the urlpatterns attribute. You have to pass the actual module, or a string reference to the module, to include(), not the list of urlpatterns itself.

https://docs.djangoproject.com/en/2.0/topics/http/urls/#url-namespaces-and-included-urlconfs

urls.py

from django.urls import include, path

urlpatterns = [
    path('polls/', include('polls.urls')),
]

polls/urls.py

from django.urls import path

from . import views

app_name = 'polls'
urlpatterns = [
    path('', views.IndexView.as_view(), name='index'),
    path('/', views.DetailView.as_view(), name='detail'),
    ...
]

have fun!
