Question

我目前正在Qt中构建一个多用户日历应用程序，并打算使用firebase实时数据库来处理用户数据和计划任务。

每个用户都可以登录该应用并选择一旦点击“保存”的日期。按钮，将锁定他们的名字。我以前没有使用firebase的经验，并且想要开始构建数据库的一些帮助，我希望能够将用户分成几个部门。

下面是我的应用程序上的日历页面的代码，我将什么内容放入firebase以便能够连接这两个？

任何帮助都会非常感激!!

如果我理解正确，您还没有将Firebase集成到您的Qt项目中？

您可以查看此插件，以便在Qt Quick中使用Firebase：https://v-play.net/doc/plugin-firebase/

然后，您可以收听reatimeValueChanged信号并相应地更新日历。
