[python] Django Rest Framework-뷰 이름 “user-detail”을 사용하여 하이퍼 링크 된 관계에 대한 URL을 확인할 수 없습니다.

Django Rest Framework에서 사용자가 로그인하여 와인 저장고를 볼 수있는 프로젝트를 구축하고 있습니다. 내 ModelViewSets가 제대로 작동하고 갑자기이 실망스러운 오류가 발생합니다.

보기 이름 “user-detail”을 사용하여 하이퍼 링크 된 관계에 대한 URL을 확인할 수 없습니다. API에 관련 모델을 포함하지 못했거나이 lookup_field필드 에서 속성을 잘못 구성했을 수 있습니다.

트레이스 백은 다음을 보여줍니다.

맞춤 이메일 사용자 모델이 있고 models.py의 병 모델은 다음과 같습니다.

class Bottle(models.Model):    
      wine = models.ForeignKey(Wine, null=False)
      user = models.ForeignKey(User, null=False, related_name='bottles')

내 시리얼 라이저 :

class BottleSerializer(serializers.HyperlinkedModelSerializer):

    class Meta:
        model = Bottle
        fields = ('url', 'wine', 'user')

class UserSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('email', 'first_name', 'last_name', 'password', 'is_superuser')

내 의견 :

class BottleViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows bottles to be viewed or edited.
    """
    queryset = Bottle.objects.all()
    serializer_class = BottleSerializer

class UserViewSet(ListCreateAPIView):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = User.objects.all()
    serializer_class = UserSerializer

마지막으로 URL :

router = routers.DefaultRouter()
router.register(r'bottles', views.BottleViewSet, base_name='bottles')

urlpatterns = patterns('',
    url(r'^', include(router.urls)),
    # ...

사용자 세부 정보보기가없고이 문제의 원인이 어디인지 알 수 없습니다. 어떤 아이디어?

감사
