Question

我尝试编写API i DRF的代码，这将允许我添加一些用户个人资料信息。因此，我创建了如下新模型：

models.py

from django.db import models
from django.contrib.auth.models import User

class UserSavedPreferences(models.Model): 
    employeeView = models.BooleanField(default=True)
    owner = models.OneToOneField(User, related_name="AppSavedProfile", on_delete=models.CASCADE, null=True)

现在，我为该模型准备了一个序列化器，如下所示：

serializers.py

from rest_framework import serializers
from django.contrib.auth.models import User
from accounts.models import UserSavedPreferences
from django.contrib.auth import authenticate

#UserSavedPreferences serializer

class UserSavedPreferencesSerializer(serializers.HyperlinkedModelSerializer): 

    class Meta: 
        model = UserSavedPreferences 
        fields = ( 
            'url',
            'pk',
            'employeeView'
        )

下面，我将我的代码与View相关：

view.py

from rest_framework import generics, permissions
from rest_framework.response import Response
from knox.models import AuthToken
from .serializers import UserSerializer, RegisterSerializer, LoginSerializer, ChangePasswordSerializer, UserSavedPreferencesSerializer
from accounts.models import UserSavedPreferences
from rest_framework import status
from django.contrib.auth.models import User
from . import serializers
from rest_framework.permissions import IsAuthenticated   

class UserSavedPreferencesList(generics.ListCreateAPIView): 
    permission_classes = [
        permissions.IsAuthenticated
    ]

    queryset = UserSavedPreferences.objects.all()
    serializer_class = UserSavedPreferencesSerializer 
    name = 'usersavedpreferences-list' 

class UserSavedPreferencesDetail(generics.RetrieveUpdateDestroyAPIView):
    permission_classes = [
        permissions.IsAuthenticated
    ] 

    queryset = UserSavedPreferences.objects.all()
    serializer_class = UserSavedPreferencesSerializer 
    name = 'usersavedpreferences-detail'

最后，我将自己的网址编码如下：

urls.py

from django.urls import path, include
from .api import RegisterAPI, LoginAPI, UserAPI, ChangePasswordAPI, UserSavedPreferencesList, UserSavedPreferencesDetail
from knox import views as knox_views
from django.conf.urls import url

urlpatterns = [ 
  url(r'^auth/user-save-preferences/$', UserSavedPreferencesList.as_view()), 
  url(r'^auth/user-save-preferences/(?P<pk>[0-9]+)$', UserSavedPreferencesDetail.as_view())
]

我的目标是能够发送GET，POST，DELETE和PATCH请求，这将使我能够基于UserSavedPreferences模型添加UserProfile并更改UserSavedPreferences.EmployeeView属性。

但是当我发送带有以下正文的POST时：

{
    "employeeView": "True",
    "owner": 3
}

我收到这样的错误500：

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

You're seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard page generated by the handler for this status code.

你能告诉我在这里我做错了什么吗？
