我正在尝试使用Django rest框架在Django应用中添加自定义权限。我创建了一个API n在邮递员中对其进行了测试,对于经过身份验证的用户来说效果很好。但是,当我访问详细信息视图时,它不显示详细信息。例如,当我访问http://localhost:8000/placeslist/时,它会显示所有地点,但是当我尝试http://localhost:8000/placeslist/1/时,它会显示您没有权限。我不知道哪里出错了
models.py
class Places(BaseModel):
name = models.CharField(max_length=255,null=True,default='')
owner=models.ForeignKey('auth.User',related_name='place_list',on_delete=models.CASCADE,null=True)
Views.py
class PlacesView(generics.ListCreateAPIView):
queryset = Places.objects.all()
serializer_class = PlacesSerializer
permission_classes = (permissions.IsAuthenticated, IsOwner)
def perform_create(self,serializer):
serializer.save(owner=self.request.user)
class PlacesDetailView(generics.RetrieveUpdateDestroyAPIView):
queryset = Places.objects.all()
serializer_class = PlacesSerializer
permission_classes = (permissions.IsAuthenticated, IsOwner)
Permission.py
class IsOwner(BasePermission):
def has_object_permission(self, request, view, obj):
if isinstance(obj, Places):
return obj.owner == request.user
return obj.owner == request.user
Serializer.py
class PlacesSerializer(serializers.ModelSerializer):
owner = serializers.ReadOnlyField(source='owner.username')
class Meta:
model = Places
fields =('id','name','owner')
urls.py
url(r'^placeslist/$', PlacesView.as_view(), name="place"),
url(r'placeslist/(?P<pk>[0-9]+)/$',PlacesDetailView.as_view(),
name="place_details"),
url(r'^get-token/', obtain_auth_token),
Settings.py
....
REST_FRAMEWORK = {
'DEFAULT_PERMISSION_CLASSES': (
'rest_framework.permissions.IsAuthenticated',
),
'DEFAULT_AUTHENTICATION_CLASSES': (
'rest_framework.authentication.BasicAuthentication',
'rest_framework.authentication.TokenAuthentication',
)
}
....

这是由于您的自定义权限,您试图访问实例(所有者为pk = 1)时,所有者不是您当前正在使用的用户。
检查该地方的所有者。
您还可以只删除视图中的permissions.IsAuthenticated
,因为您已经将其放入默认权限类中。
