django - DRF - 为额外操作路由额外的 HTTP 方法

Question

我正在尝试实现 routing additional HTTP methods for extra actions使用 django rest 框架，但在 runserver

处出现错误

AttributeError: 'function' object has no attribute 'mapping'

无法弄清楚问题所在 - Django 2.1.2、Python 3.6.5

class CustomerAPIViewSet(mixins.ListModelMixin,
                         mixins.CreateModelMixin,
                         mixins.RetrieveModelMixin,
                         mixins.UpdateModelMixin,
                         viewsets.GenericViewSet):
    permission_classes = (IsAuthenticated, CustomerAdminPermissions)
    serializer_class = CustomerSerializer
    queryset = Customer.objects.all()

    @action(detail=True)
    def order_guide(self, request, **kwargs):
        instance = self.get_object()
        serializer = CustomerDetailSerializer(instance)
        return Response(serializer.data)

    @order_guide.mapping.put
    def order_create(self, request, **kwargs):
        instance = self.get_object()
        serializer = CustomerDetailSerializer(instance, data=request.data)
        serializer.is_valid(raise_exception=True)
        serializer.save()
        return Response(serializer.data)

Django Rest Framework 版本 3.9.0 中引入了用于路由附加 HTTP 方法的 @action.mapping。引发 AttributeError 的早期版本。尝试升级您的 DRF 版本。

pip install djangorestframework --upgrade
