Question

我正在使用Django ..

以下是观点

class SettingsValues(generics.ListAPIView):
    serializer_class = SettingsSerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,)

    def get_queryset(self):
        queryset = Settings.objects.all()
        queryset = queryset.filter(user=self.request.user.id)
        return queryset

class SettingsValuesUpdate(generics.UpdateAPIView):
    queryset = Settings.objects.all()
    serializer_class = SettingsSerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,)

    def perform_update(self, serializer):
        serializer.save(user=self.request.user.id)

这是我的模型

class Settings(models.Model):
    user = models.OneToOneField('auth.User', related_name='settings', on_delete=models.CASCADE)
    boolean1 = models.BooleanField(default=False)
    boolean2 = models.BooleanField(default=False)
    boolean3 = models.BooleanField(default=False)
    string1 = models.CharField(max_length=100, default='No description')

我的序列化程序

class SettingsSerializer(serializers.ModelSerializer):
    class Meta:
        model = Settings
        fields = ('id', 'boolean1', 'boolean2', 'boolean3', 'string1')

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = ('id', 'username', 'email', 'password' ,'settings', 'image')
    extra_kwargs = {'password': {'write_only': True}}

我的网址

url(r'^settings/?$', views.SettingsValues.as_view()),
url(r'^updsettings/?$', views.SettingsValuesUpdate.as_view()),

我正在使用Angular 2或邮差应用程序并不重要..当我返回设置时它工作正常。但是当我尝试更新用户设置（PUT）时，它显示错误

使用名为＆＃34; pk＆＃34;的URL关键字参数调用预期视图SettingsValuesUpdate。修复您的网址，或在视图上正确设置.lookup_field属性

有什么想法吗？

修改

回答vinay kumar的回答，我的观点是

class SettingsValuesUpdate(viewsets.ModelViewSet):
    queryset = Settings.objects.all()
    serializer_class = SettingsSerializer
    permission_classes = (permissions.IsAuthenticatedOrReadOnly,)

    @detail_route(methods='PUT')
    def perform_update(self, serializer):
        serializer.save(user=self.request.user.id)

但仍然存在错误{＆＃34; detail＆＃34;：＆＃34; Method \＆＃34; PUT \＆＃34;不允许。＆＃34;}

Answer 1

请尝试这种方式。

from django.conf.urls import include, urls   
from rest_framework import routers

from .views import SettingsValues, SettingsValuesUpdate

router = routers.SimpleRouter()
router.register(r'settings', SettingsValues, base_name='setting_values')
router.register(r'updsettings', SettingsValuesUpdate, base_name='setting_value_update')

urlpatterns = [
   url(r'^', include(router.urls)),
]

Answer 2

在我的情况下，我从get_queryset(self)返回了一个对象，然后将其更改为get_object(self)解决了我的问题

使用名为pk的url关键字参数调用预期视图
