python - HyperlinkedModelSerializer 在 django rest 框架中使用 auth.User 抛出 ImproperlyConfigured 错误

Question

我有以下使用 django rest 框架的代码。

网址.py

urlpatterns = [
    url(r'^portfolio1/', include('portfolio1.urls')),
    url(r'^admin/', admin.site.urls),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))]

portfolio1/urls.py

app_name = 'portfolio1'
urlpatterns = [
    url(r'^$', \
            views.api_root),
    url(r'^users/$', \
            views.UserList.as_view(), \
            name='user-list'),
    url(r'^users/(?P<pk>[-\d]+)/$', \
            views.UserDetail.as_view(), \
            name='user-detail'),
]
urlpatterns = format_suffix_patterns(urlpatterns)

portfolio1/serializers.py

from django.contrib.auth.models import User as AuthUser
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = AuthUser
        fields = ('id', 'username', 'url')

portfolio1/views.py

from django.contrib.auth.models import User as AuthUser
class UserList(generics.ListAPIView):
    queryset = AuthUser.objects.all()
    serializer_class = UserSerializer

class UserDetail(generics.RetrieveAPIView):
    queryset = AuthUser.objects.all()
    serializer_class = UserSerializer

@api_view(('GET',))
@permission_classes((permissions.AllowAny, ))
def api_root(request, format=None):
    return Response({
        'users': reverse('user-list', request=request, format=format)
    })

我收到以下错误。

ImproperlyConfigured: Could not resolve URL for hyperlinked relationship using view name "user-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field.

我知道错误的含义，但不确定我为什么会收到它。它与 django rest 框架(https://github.com/tomchristie/django-rest-framework/issues/2711)的版本控制有什么关系吗？我已确保我没有犯与 HyperlinkedIdentityField returning error only on User model 相同的错误.

Answer 1

在 portfolio1/urls.py 中删除 app_name = 'portfolio1'。
