我正在创建一个带有Django后端和React前端的Web。当从前端提交一个对象并试图获取它时，它不工作，除非我重新启动后端，这时它应该立即更新。在管理视图中，它会立即显示出来，但是由于某种原因，它无法获取它，直到我重新启动
这里是设置文件，以防万一

这是我正在检索的视图，它不会在运行时更新

class PublicadosListView(generics.ListAPIView):

    permission_classes = []
    def get_serializer_class(self):
        # Utiliza el serializador adecuado según el tipo de objeto
        if isinstance(self.queryset[0], Resenya):
            return ResenyaSerializer
        elif isinstance(self.queryset[0], Consulta):
            return ConsultaSerializer

我试过从管理视图、 Postman 和前端添加该项目，但它只在服务器重新启动时显示。有什么线索吗？
