覆盖引擎中的控制器（特别是在设计中）

Question

我想在登录/注销时删除 Devise 的 set_flash_message，所以我创建了 我自己的session_controller，从devise的逐字复制。我将视图复制到应用程序/视图/会话，并更改了路线。现在，当我登录时，它会将我重定向回登录页面。 Rails 日志显示

Processing by SessionsController#new as HTML

当我使用内置会话控制器时不会显示哪些内容。有什么想法吗？

我可以在不覆盖控制器的情况下解决这个问题，但我怀疑我无论如何都会在某个时候这样做并遇到同样的问题。何塞不知道。我该如何解决这个问题？

app/controllers/sessions_controller.rb：与 /Users/jay/.rvm/gems/ruby-1.9.2-p180/gems/devise-1.2.1/app/controllers/devise/sessions_controller.rb 相同。

config/routes.rb：

  devise_for :users, :controllers => { :sessions => :sessions }
  ...

使用我的控制器副本进行rails输出：

如果您只想自定义 devise 使用的消息，只需编辑 devise.en.yml 文件

config/locales/devise.en.yml

en:
  ...
  devise:
    sessions:
      signed_in: 'Signed in successfully.'
      signed_out: 'Signed out successfully.'
