重置密码时设计中断

Question

我正在使用 devise，我认为一切正常，直到我试图重置密码。我收到以下错误。设计找不到名为布局/电子邮件的模板。为什么它甚至想要那个？我的印象是，在表单发布后，devise 会重定向到用户登录页面。

我怀疑设计无法找到“reset_password_instructions.html.haml”文件，因为它显然能够生成重置令牌，但实际上没有发送电子邮件。根据下面的错误消息，这听起来像是正确的诊断吗？

我该怎么做才能解决这个问题？我猜我必须通过覆盖控制器来修改设计，但我不确定。有什么建议吗？

Devise 在重定向用户之前发送一封带有重置令牌的电子邮件。发送电子邮件还需要模板和布局。在您的情况下，此步骤失败是因为在您的代码中的某处，您可能为 ActionMailer 类指定了layout 'email'，但实际上并未创建此布局模板。

尝试添加至少包含以下内容的文件app/views/layouts/email.html.haml：

= yield

（或 .html.erb 模板中的 <%= yield %>）。
