我为Devise设置了以下vanilla重置密码邮件程序。这使得重置密码邮件在开发中具有正确的URL，但是在生产中抛出了错误
undefined local variable or method 'controller' for #<ResetPasswordMailer:0x00000007248f68>
看起来帮助程序的加载速度很好，但生成的路径只在生产中出现问题。
部分堆栈跟踪：
actionview (4.1.1) lib/action_view/routing_url_for.rb:99:in `_routes_context'
actionpack (4.1.1) lib/action_dispatch/routing/route_set.rb:372:in `block (2 levels) in define_mounted_helper'

<p>Hello <%= @resource.email %>!</p>
<p>Someone has requested a link to change your password. You can do this through the link below.</p>
<p><%= link_to 'Change my password', edit_password_url(@resource, reset_password_token: @token) %></p>
<p>If you didn't request this, please ignore this email.</p>
<p>Your password won't change until you access the link above and create a new one.</p>
更新
这是由config.eager_load = true中的production.rb设置引起的。将其更改为false似乎不是最佳解决方案。

问题是由Rails 4.1.2上的config.eager_load = true引起的。升级到Rails 4.2.0后，它可以正常工作。
