如何在DRF的视图集中使用自定义列表方法和自定义操作？

from rest_framework import viewsets
from rest_framework.decorators import action
from rest_framework.response import Response

class MyViewSet(viewsets.ModelViewSet):
    queryset = MyModel.objects.all()
    serializer_class = MySerializer

    @action(detail=False, methods=['get'])
    def custom_list_method(self, request):
        # 自定义列表方法的实现逻辑
        queryset = self.get_queryset()
        # 进行一些筛选、排序等操作
        serializer = self.get_serializer(queryset, many=True)
        return Response(serializer.data)

    @action(detail=True, methods=['post'])
    def custom_action(self, request, pk=None):
        # 自定义操作的实现逻辑
        instance = self.get_object()
        # 进行一些操作，如更新、删除等
        serializer = self.get_serializer(instance)
        return Response(serializer.data)

from django.urls import include, path
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'mymodels', MyViewSet)

urlpatterns = [
    path('', include(router.urls)),
]
