问在url_path中使用参数测试DRF GenericViewSet

EN

class HwView(mixins.ListModelMixin, viewsets.GenericViewSet):

    @action(detail=False, methods=['get'], url_path='switch_state/(?P<switch_id>\d+)')
    def switch_state(self, request, switch_id):
        print(f'sw: {switch_id}')
        
        results = {"state": 'ok'}

        return Response(results)

from rest_framework import routers
router = routers.DefaultRouter()

router.register(r'hw', hw_views.HwView, basename='HwModel')

from rest_framework.test import APIRequestFactory, APITestCase


class TestCommandProcessor(APITestCase):
    def setUp(self):
        pass

    def test_switch_state(self):
        factory = APIRequestFactory()
        request = factory.get(
            '/api/hw/switch_state/3',
        )

        view = HwView.as_view({'get': 'switch_state'}, basename='HwModel')

        response = view(request)

        self.assertIn('state', response.data)
        self.assertEqual('ok', response.data['state'])

TypeError: switch_state() missing 1 required positional argument: 'switch_id'
