设置设计登录为root页面 [英] Setting Devise Login to be root page

问题描述

我正在为我的路线使用以下代码：

I am using the following code for my routes:

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

但是当我登出后，我转到 / logout 我收到以下错误：

But when I'm logged out and I goto /logout I get the following error:

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

No route matches {:action=>"new", :controller=>"devise/sessions"}

如何设置根路径为：sign_in action？

How do I setup the root path to be to :sign_in action?

推荐答案

关于错误找不到路径/的设计映射有一个解决方法。

To follow on from the people who are asking about the error Could not find devise mapping for path "/" there is a workaround.

你会发现你的日志中有一个线索，可能会说：

You'll find that there is a clue in your logs which will probably say:

[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]

所以我重试了这个方法，而是将它（作为@miccet suggets）包含在一个范围块中：

So I retried the approach but instead wrapping it (as @miccet suggets) inside a scope block:

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

这对我来说很好。
