ruby-on-rails - `add_route' : Invalid route name, 已在使用中:'root' (ArgumentError)

Question

我使用的是 rails 4.1.1 和 ruby​​ 2.1.1，我在设计方面遇到了问题，即我的路线。我以前用过很多次

devise_for :users

get 'pages/index'

# Route to Devise Login Page
  devise_scope :user do
    root to: "devise/sessions#new"
  end

# Directing the user after login
  authenticated :user do
    root :to => 'pages#index'
  end

但是我得到了错误

`add_route': Invalid route name, already in use: 'root'  (ArgumentError)

当尝试启动服务器时..我可以看到 root 被使用了两次，但就像我说的我过去已经能够做到这一点..有没有办法解决这个问题

谢谢

在 stackoverflow 上找到这条有用的评论

For Rails 4.0 you have to make sure you have unique names for the path helpers, like root to: "dashboard#show", as: :authenticated_root. Otherwise the authenticated root and the normal root route end up having the same name for their path helpers, which Rails 4.0 no longer allows

所以我像这样将经过身份验证的根更改为助手

 # Directing the user after login
 authenticated :user do
   root :to => 'pages#index', as: :authenticated_root
 end
