Ruby-on-rails 将设计登录设置为根页面

Setting Devise Login to be root page

提问by Logan Bailey

I am using the following code for my routes:

我正在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" 
  }

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

但是当我注销并转到时，/logout我收到以下错误：

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

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

How do I setup the root path to be to :sign_inaction?

如何设置要执行的根路径:sign_in？

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

从询问错误的人Could not find devise mapping for path "/"那里得到解决方法。

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

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]

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

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

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

This worked fine for me

这对我来说很好用

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

Just like this, tested on Rails Rails 4.1.0.rc1.

就像这样，在 Rails Rails 4.1.0.rc1 上测试。

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

I needed to set the default home root. I felt like I had tried this all night last night (prior to posting the question), but it's working now. If you're logged out, Devise attempts to redirect you to the root path which I had undefined.

我需要设置默认的主根。我觉得我昨晚（在发布问题之前）整晚都尝试过这个，但现在它正在起作用。如果您已注销，Devise 会尝试将您重定向到我未定义的根路径。

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

I got this to work with @VvDPzZ answer. But I had to modify it slightly

我得到了这个与@VvDPzZ 答案一起工作。但我不得不稍微修改一下

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

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

I had to ad to:in the root path declaration. I also removed the as: :authenticated_rootbecause I already had some places in my application referencing root_pathin links. By leaving out the as: :authenticated_rootpart I didn't have to change any of my existing links.

我不得不to:在根路径声明中添加广告。我还删除了 ，as: :authenticated_root因为我的应用程序中已经有一些地方root_path在链接中引用。通过省略该as: :authenticated_root部分，我不必更改任何现有链接。

I guess you have different user roles. If you do you have to add a scope like this to the users resource:

我猜你有不同的用户角色。如果您这样做，您必须将这样的范围添加到用户资源中：

  devise_scope :user do
    get "/logout" => "devise/sessions#destroy"
  end

Some of these solutions are way too complex. Just use Rails:

其中一些解决方案太复杂了。只需使用 Rails：

Add 'get' 'users/root', to: 'users#root'to config/routes.rb.

添加'get' 'users/root', to: 'users#root'到 config/routes.rb。

In UsersController do something like:

在 UsersController 中执行以下操作：

def root
  if user_signed_in?
    redirect_to root_for_signed_in_user_path (or whatever)
  else
    redirect_to new_user_session_path
  end
end

Using rails 3.2and devise 3.2.3I manage to setup my home page "home#index" (controller#action) as the login page making the following changes.

使用rails 3.2和devise 3.2.3我设法将我的主页“ home#index”（controller#action）设置为登录页面，并进行了以下更改。

#1Added the login form to the home page:

#1在首页添加登录表单：

<%= simple_form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
    <%= f.input :email %>
    <%= f.input :password %>
    <%= f.button :submit %>
<% end %>

#2Added methods resource_name, resource and devise_mapping to app/heldpers/application_helper.rb:

#2向app/heldpers/application_helper.rb添加了方法 resource_name、resource 和 devise_mapping ：

def resource_name
  :user
end

def resource
  @resource ||= User.new
end

def devise_mapping
  @devise_mapping ||= Devise.mappings[:user]
end

#3Created a custom sessions controller app/controllers/users/sessions_controller.rb:

#3创建自定义会话控制器app/controllers/users/sessions_controller.rb：

class Users::SessionsController < Devise::SessionsController

   protected

   # This method tell sessions#create method to redirect to home#index when login fails.
   def auth_options
      { scope: resource_name, recall: 'home#index' }
   end

end

#4Skip the session routes and setup the custom sessions controller in config/routes.rb:

#4跳过会话路由并在config/routes.rb 中设置自定义会话控制器：

devise_for :users, path: 'auth', skip: [:sessions],
           controllers: {
               sessions: 'users/sessions'
           }

as :user do
  get 'auth/sign_in' => 'home#index', as: :new_user_session
  post 'auth/sign_in' => 'users/sessions#create', as: :user_session
  delete 'auth/sign_out' => 'users/sessions#destroy', as: :destroy_user_session
end
