序列化程序.py

如何使目标非空?

结果目标是空的,因为这就是我在模型中创建通知的方式

notify.send(user, recipient=user, verb='you reached level 10')

如果我想要一个非空的目标,我应该指定一个

notify.send(user, recipient=user, target=user, verb='you reached level 10')

注意:问题中没有生成json的django视图。在我们的网址.py我们从应用程序连接到通知视图的路径。

    path(
      "alerts/",
      views.NotificationViewSet.as_view({"get": "list"}),
      name="notifications",
    ),
