我正在尝试创建一个Django休假管理系统，每个用户都可以在该系统中登录并申请休假，并接收有关其批准或拒绝的电子邮件通知。
管理员可以选择更改个人资料，接受和拒绝，并可以阻止某人申请休假。
我希望你们能仔细阅读我的代码，并告诉我是否走了正确的道路，并为我提供了一些模型和代码。 同样在请求离开中，我想通过表单将请求与当前登录的用户一起传递。以及如何使用电子邮件选项发送和接收电子邮件。
预先感谢

我期望的结果是看到用户登录并申请请假。 在获得批准的休假后，该休假将从他所准予的全部休假中扣除，例如如果他申请3个年假，将从10个总年假中扣除，并在主屏幕上显示为剩余的7个年假。
，如果他用完了所有叶子，就会产生一个错误。 管理员还可以如何阻止他即使请假也可以申请休假。
