将Devise Login设置为根页面

Question

我为我的路线使用以下代码:

devise_for :user, 
  :as => '', 
  :path_names => { 
    :sign_in => "", 
    :sign_out => "logout", 
    :sign_up => "register" 
  }

但是当我退出并且我转到后,/logout我收到以下错误:

没有路由匹配{:action =>"new",:controller =>"devise/sessions"}

如何设置要:sign_in采取行动的根路径？

Answer 1

要从询问错误的人Could not find devise mapping for path "/"那里继续,有一个解决方法.

你会发现你的日志中有一条线索可能会说:

[Devise] Could not find devise mapping for path "/".
This may happen for two reasons:

1) You forgot to wrap your route inside the scope block. For example:

  devise_scope :user do
    match "/some/route" => "some_devise_controller"
  end

2) You are testing a Devise controller bypassing the router.
   If so, you can explicitly tell Devise which mapping to use:

   @request.env["devise.mapping"] = Devise.mappings[:user]

所以我重新尝试了这个方法,而是将它包装起来(如@miccet suggets)在一个范围块中:

devise_scope :user do
  root to: "devise/sessions#new"
end

这对我来说很好

Answer 2

devise_for :users

devise_scope :user do
  authenticated :user do
    root 'home#index', as: :authenticated_root
  end

  unauthenticated do
    root 'devise/sessions#new', as: :unauthenticated_root
  end
end

就像这样,在Rails Rails 4.1.0.rc1上测试.

Answer 3

root :to => "devise/sessions#new"

我需要设置默认的home root.我觉得昨晚(在发布问题之前)我整夜都试过这个,但它现在正在运作.如果您已注销,Devise会尝试将您重定向到我未定义的根路径.

_{(这是作为建议的编辑发布的,但应该是它自己的答案.我不知道它是否有意义.亲爱的匿名编辑:随意将此答案重新发布为您自己的,并留下评论所以我会删除这个副本.)}

root :to => redirect("/users/login")

Answer 5

我得到这个与@VvDPzZ答案一起工作.但我不得不稍微修改它

  devise_scope :business_owner do
    authenticated  do
      root to: 'pages#dashboard'
    end

    unauthenticated do
      root to: 'devise/sessions#new', as: 'unauthenticated_root'
    end
  end  

我必须to:在根路径声明中做广告.我也删除了as: :authenticated_root因为我已经在我的应用程序中有一些地方引用root_path链接.通过省略as: :authenticated_root部分,我不必更改任何现有链接.
