Question

我花了几个小时尝试调试问题。我还无法理解如何设置HyperlinkedModelSerializer。

能否请您指出我做错了什么？此外，除了官方文档外，是否还有任何其他有关更好理解超链接关系的好教程？谢谢！

错误

在/ settings /中配置不正确无法解析URL   使用视图名称“设置详细信息”的超链接关系。你可以   未能将相关模型包含在您的API中，或不正确   在此字段上配置了lookup_field属性。

...

在处理上述异常期间（“设置”为反向   详细信息”和关键字参数“ {'settings_id'：   找不到UUID（'24aee4eb-8f71-4336-8c36-a96c9e4447c9'）}。 1个图案   尝试过：['settings // $']），发生了另一个异常：

models.py

class Settings(models.Model):
    # General
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    createdAt = models.DateTimeField(auto_now_add=True)
    updatedAt = models.DateTimeField(auto_now=True)

    # Token
    publicToken = models.CharField(max_length=100)
    secretToken = models.CharField(max_length=100)

serializers.py

class SettingsListSerializer(serializers.HyperlinkedModelSerializer):
    url = serializers.HyperlinkedIdentityField(
        view_name = "Settings Detail",
        lookup_field='id',
        lookup_url_kwarg='settings_id'
    )

    class Meta:
        model = Settings
        exclude = ('id', 'createdAt', 'updatedAt',)

class SettingsDetailSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Settings
        exclude = ('id','createdAt', 'updatedAt',)

urls.py

from django.conf.urls import url
from app import views

urlpatterns = [
    url(r'^$', views.HomeView.as_view(), name=views.HomeView.name),
    url(r'^settings/$', views.SettingsListView.as_view(), name=views.SettingsListView.name),
    url(r'^settings/<uuid:settings_id>/$', views.SettingsDetailView.as_view(), name=views.SettingsDetailView.name),
]

views.py

class SettingsListView(generics.ListCreateAPIView):
    queryset = Settings.objects.all()
    serializer_class = SettingsListSerializer
    permission_classes = (IsAuthenticated,)
    name = "Settings List"

class SettingsDetailView(generics.RetrieveUpdateDestroyAPIView):
    serializer_class = SettingsDetailSerializer
    permission_classes = (IsAuthenticated,)
    name = "Settings Detail"

    def get_queryset(self):
        id = self.kwargs.get(self.lookup_url_kwarg)
        setting = Settings.objects.filter(id=id)
        return setting

无法使用视图名称“设置详细信息”解析超链接关系的URL
