我正在研究Michael Hartl Railstutorial.org - 第10章 - 密码重置。 我在开发环境（Cloud9）中配置了电子邮件，发送了电子邮件。 一切正常，直到用户点击系统发送的电子邮件。它不是被重定向到密码重置表单，而是转到根目录。 与本书相比，即使使用来自其他成员的相同项目代码 - 也找不到任何故障。很可能它是非常简单的东西，但我找不到它:( 任何帮助表示赞赏...

完成。只需重新创建所有文件，根据书籍进行检查即可正常工作

它必须是经过验证的用户，它仅对管理员有效，因为默认情况下有效
我为我想首先在控制台中重置密码的用户执行了此操作
User.find_by_email（'notadmin@gmail.com'）。update（已激活：true）
效果很好
