Как вызвать сериалайзер сразу с двумя моделями?

Question

[bituke]

у меня имеется кастомный сериалайзер, который работает сразу с двумя моделями, такой запрос фронтера, хочет именно так:
{
capex: {}, // первая форма
object_settings:{}, //вторая форма
}

class CapexSerializer(serializers.Serializer):
	capex = ProjectCapexSerializer(read_only=True)
	object_settings = CapexObjectSettingsSerializer(read_only=True)
	class Meta:
		fields = '__all__'

Но я не могу правильно написать функцию list в ListCreateAPIView

class ProjectCapexListView(generics.ListCreateAPIView):
	serializer_class = serializers.CapexSerializer
	filter_backends = [DjangoFilterBackend]
	filterset_fields = '__all__'
	permission_classes = [permissions.IsOwnerCapex, IsAuthenticated]

	def list(self, request, *args, **kwargs):
		user = request.user
		capexs = models.ProjectCapex.objects.filter(project__author=user)
		object_settings = models.CapexObjectSetting.objects.filter(capex__project__author=user)
		capex_serializer = self.get_serializer(capexs, object_settings, many=True)
		capex_serializer.is_valid()
		return Response(capex_serializer.data)

Но он выдает только capex :(

  ]

А должен выдавать такой ответ:

"results": [

      },
      "object_settings": {
        "id": 0,

          {

            "file_name": "string",
            "file_format": "string",
            "file": "string",
            "create_date": "2022-07-13T16:27:20.926Z",
            "_object": 0
          }
        ],

        "capex": 0
      }
    }
  ]
}

подскажите, как это должно быть сделано?
