如何在ViewSet中使用基于类的视图？

from rest_framework import generics
from rest_framework.viewsets import ViewSet
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated

from rest_framework import generics
from rest_framework.viewsets import ViewSet
from rest_framework.response import Response
from rest_framework.permissions import IsAuthenticated

class MyViewSet(ViewSet):
    permission_classes = [IsAuthenticated]

    def list(self, request):
        queryset = MyModel.objects.all()
        serializer = MySerializer(queryset, many=True)
        return Response(serializer.data)

    def create(self, request):
        serializer = MySerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=201)
        return Response(serializer.errors, status=400)

    def retrieve(self, request, pk=None):
        queryset = MyModel.objects.all()
        my_object = generics.get_object_or_404(queryset, pk=pk)
        serializer = MySerializer(my_object)
        return Response(serializer.data)

    # 自定义操作
    @action(detail=True, methods=['post'])
    def custom_action(self, request, pk=None):
        my_object = self.get_object()
        # 执行自定义操作逻辑
        return Response("Custom action executed")

from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'my-models', MyViewSet, basename='my-models')
urlpatterns = router.urls
