我有一个 ViewSet ,其中permission_classes
设置为(permissions.IsAuthenticated,)
,但是我希望此视图在方法为retrieve()
时允许未经身份验证的访问。 / p>
这是我的 ViewSet :
class AlbumViewSet(viewsets.ModelViewSet):
permission_classes = (permissions.IsAuthenticated,)
queryset = proxies.AlbumProxy.objects.all()
serializer_class = serializers.AlbumSerializer
filter_backends = (DjangoFilterBackend, SearchFilter, OrderingFilter,)
search_fields = ('name', 'description', 'company__name')
filter_fields = ('code', 'company')
def retrieve(self, request, pk):
password = request.query_params.get('password', None)
instance = proxies.AlbumProxy.objects.get(code=pk)
if instance.access_code != password and password != settings.MASTER_KEY:
raise Exception(_("Invalid password for album {}".format(instance.code)))
instance_to_return = serializers.AlbumSerializer(instance=instance, context={'request': request}).data
instance_to_return.pop('access_code')
return Response(instance_to_return)
有没有方法可以在方法permission_classes
启用时禁用retrieve()
,但是在其他情况下仍可以使它工作?

您可以像这样覆盖get_permissions:
def get_permissions(self):
if self.action == 'retrieve':
return [] # This method should return iterable of permissions
return super().get_permissions()
