我正在Django Rest Framework中建立一个项目,用户可以登录查看其酒窖。我的ModelViewSets工作正常,突然我收到了一个令人沮丧的错误:
无法使用视图名称“用户详细信息”解析超链接关系的URL。您可能无法在API中包含相关模型,或者
lookup_field
在此字段上配置了错误的属性。

我有一个自定义的电子邮件用户模型,并且models.py中的瓶子模型是:
class Bottle(models.Model):
wine = models.ForeignKey(Wine, null=False)
user = models.ForeignKey(User, null=False, related_name='bottles')
我的序列化器:
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')
我的看法:
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
最后是URL:
router = routers.DefaultRouter()
router.register(r'bottles', views.BottleViewSet, base_name='bottles')
urlpatterns = patterns('',
url(r'^', include(router.urls)),
# ...
我没有用户详细信息视图,也看不到此问题可能来自何处。有任何想法吗?
谢谢
