Django Rest框架中的action decorator方法需要在类http_method_names中指定

DRF版本是3.11.2

我正在编写一些现有代码,向视图集中添加一个额外的“删除”操作,但我得到了 405 Method not allowed 考虑下面的例子

class UserViewSet(ModelViewSet):
    ....
    queryset = User.objects.all()
    http_method_names = ['get', 'post']

    @action(detail=True, method=['delete'])
    def delete_profile(self, request, pk=None)
        Profile.objects.get(user=pk).delete()
        ....

就像我说的,当我调用delete方法 /user/123/delete_profile ,我明白了 405方法不允许 然而,如果我加上 delete 到 http_method_names 如下所示,它运行良好。

class UserViewSet(ViewSet):
    ....
    queryset = User.objects.all()
    http_method_names = ['get', 'post', 'delete']

    @action(detail=True, method=['delete'])
    def delete_profile(self, request, pk=None)
        Profile.objects.get(user=pk).delete()
        ....

但这并不理想,因为我不想允许对用户执行“删除”操作,同时我可以覆盖 删去 / destroy 要避免用户在viewset上被删除,此方法非常优雅。

所以问题是,这是一个bug还是设计的?所谓设计,我指的是由 @action 假设正在处理在中定义的相同模型 ModelViewSet (在这种情况下是用户,而不是个人资料)?

class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer queryset = User.objects.all() @action(detail=True, methods=['delete']) def delete_profile(self, request, pk=None): Profile.objects.get(user=pk).delete() return Response(status=status.HTTP_204_NO_CONTENT)

class UserViewSet(viewsets.ModelViewSet): serializer_class = UserSerializer queryset = User.objects.all() @action(detail=True, methods=['delete']) def delete_profile(self, request, pk=None): .... def destroy(self, request, *args, **kwargs): return Response(status=status.HTTP_405_METHOD_NOT_ALLOWED)
