重置密码时设计中断

Question

我使用设计，我认为一切正常，直到我tred重置密码。我收到下面的错误。设计无法找到名为布局/电子邮件的模板。它为什么要这样做？我的印象是，在发布表单后，设计会重定向到用户登录页面。

我怀疑devise找不到“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？

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。有什么建议么？

在重定向用户之前，设计发送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。在你的情况下，这一步失败了，因为在你的代码的某个地方，你可能为ActionMailer类指定了layout 'email'，但实际上并没有创建这个布局模板。

尝试添加文件app/views/layouts/email.html.haml这至少包含这样的：

= yield 

（或在.html.erb模板<%= yield %>）。
