[python] include ()에서 네임 스페이스를 사용할 때 app_name에 대한 ImproperlyConfiguredError

나는 현재 Django를 시험하고 있습니다. urls.py namespace의 내 include()s 중 하나 에서 인수를 사용합니다. 서버를 실행하고 찾아 보려고하면이 오류가 발생합니다.

File "C:\Users\User\AppData\Local\Programs\Python\Python36-32\lib\site-packages\django\urls\conf.py", line 39, in include
    'Specifying a namespace in include() without providing an app_name '
django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead.

다음은 내 urls.py 파일입니다.

#project/urls.py

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^reviews/', include('reviews.urls', namespace='reviews')),
    url(r'^admin/', include(admin.site.urls)),
]

과

#app/urls.py

from django.conf.urls import url

from . import views

urlpatterns = [
    # ex: /
    url(r'^$', views.review_list, name='review_list'),
    # ex: /review/5/
    url(r'^review/(?P<review_id>[0-9]+)/$', views.review_detail, name='review_detail'),
    # ex: /wine/
    url(r'^wine$', views.wine_list, name='wine_list'),
    # ex: /wine/5/
    url(r'^wine/(?P<wine_id>[0-9]+)/$', views.wine_detail, name='wine_detail'),
]

app_name오류 메시지에 명시된대로 무엇을 통과 합니까?

답변

url(r'^reviews/', include(('reviews.urls', 'reviews'), namespace='reviews')),

# reviews/urls.py  <-- i.e. in your app's urls.py

app_name = 'reviews'
     

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('', include('apps.main.urls')),
    path('admin/', admin.site.urls),
]

from django.urls import path
from . import views

app_name = 'main_app'

urlpatterns = [
    path('', views.index, name='index'),
]

<a href="{% url main_app:index' %}"> link </a>

from django_saml2_pro_auth.urls import urlpatterns

app_name = 'saml'

from django.urls import include, re_path as url

urlpatterns = [
    ..., url(r'', include('your_app.saml_urls', namespace='saml')), ...
]

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

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

def get_absolute_url(self):
    from django.urls import reverse
    return reverse('polls.index', args=[str(self.id)])

{% url 'polls:index' %}
