"在 DRF 响应中在哪里添加非模型字段？"

Question

我有以下视图和序列化程序

 class SampleListView(generics.ListCreateAPIView):
    queryset = Usecase.objects.all()
    serializer_class = UsecaseSerializer
    # permission_classes = (CustomDjangoModelPermission,)
    # filter_backends = [ObjectPermissionsFilter]

    def list(self, request):
        queryset = self.get_queryset()
        serializer = SampleSerializer(queryset, many=True)
        return Response(serializer.data)

class SampleSerializer(serializers.ModelSerializer):
     non_model_field_1 = serializer.IntegerField()
     non_model_field_2 = serializer.IntegerField()
    
    class Meta:
        model = Usecase
        fields = "__all__"
