如何将渲染器连接到视图集中的特定端点，并且仅该端点

问题描述

DRF文档显示了如何将渲染器连接到APIView，而不显示如何将其用于ViewSet中的特定操作。给定：

The DRF documentation shows how to connect a renderer to an APIView, but not how to do it for a specific action in a ViewSet. Given:

class XViewSet(ViewSet):
    serializer_class = XSerializer

    @action(detail=True, methods=['get'])
    def my_action(self, request, pk=None):
         ..

如何为 my_action 设置特定的渲染器，而不会影响视图集中的其他/默认操作？

How do I set a specific renderer for my_action, that will not affect the other/default actions in the viewset?

我当然可以为该操作创建APIView，但这会使URLs更加混乱。

I can make an APIView just for that action of course but that makes for a more messy urls.py

推荐答案

据我所知，操作接受任何可以作为类属性的参数：

As far as I can tell, the action takes any argument that can be a class attribute:

class XViewSet(ViewSet):
    serializer_class = XSerializer

    @action(detail=True, methods=['get'], renderer_classes=[yourrenderer])
    def my_action(self, request, pk=None):
         ..
