找不到路径“/ sessions / user”的设计映射devise登录错误 [英] Could not find devise mapping for path "/sessions/user" devise log in error

问题描述

过去几天很沮丧。

我有一个安装了Devise的rails应用程序，我生成了一个新的User模型，并生成了Devise视图。

当我在填写电子邮件和密码字段后点击登录时尝试以现有用户身份登录时会发生此情况：

  AbstractController :: ActionNotFound  - 找不到路径/ sessions / user的devise映射。 
这可能是由于两个原因：
 
 1）你忘了在你的范围块中包装你的路由。例如：
 
 devise_scope：user do 
 get/ some / route=> some_devise_controller
 end 
 
 2）您正在测试绕过路由器的Devise控制器。 
如果是这样，你可以明确告诉Devise使用哪个映射：
 
 @ request.env [devise.mapping] = Devise.mappings [：user]

事情是，当我注册作为一个新用户，它的工作就好了。我可以填写相应的字段，点击注册，它会通知我，我已成功登录，并将我重定向到根URL，显示用户登录。该错误只发生在我尝试登录。 / p>

这是我的路线：

  Ripelist :: Application.routes。 draw do 
 devise_for：users，path_names：{sign_in：'login'，sign_out：'logout'，sign_up：'signup'} 
 root to：'listing＃index'
 match'会话/用户到：devise / sessions＃create，通过：：post 
 
 resources：users 
 resources：listings 
 resources：categories 
 resources：会话
 end 
  

有人可以帮助吗？

解决方案

在你的routes.rb文件，尝试包装你的路由在范围块内的错误消息建议。
下面是一个例子：

  devise_scope：user do 
 getsignup，to：devise / registrations＃new
 getlogin，to：devise / sessions＃new
 getlogout，to：devise / sessions＃destroy
 end 
  

这将给你很好地命名的路线。

顺便说一句，如果你使用Rails 4，摆脱匹配方法。您需要指定HTTP动词。

OBSOLETE旧答案：

使用上面的代码。）

  devise_for：users，path_names：{sign_in：' login'，sign_out：'logout'，sign_up：'signup'} 
  

AND

  match'/ sessions / user'，to：'devise / sessions＃create'，via：：post 
  

Very frustrating for the last few days.

I have a rails app with Devise installed where I generated a new User model and I generated Devise views as well.

This happens when I try to sign in as an existing user right when I click "Log in" after filling out the email and password fields:

AbstractController::ActionNotFound - Could not find devise mapping for path "/sessions/user".
This may happen for two reasons:

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

  devise_scope :user do
    get "/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]

The thing is, when I sign up as a new user, it works just fine. I can fill in the appropriate fields, click "Sign up" and it notifies me that I've logged in successfully and redirects me to the root URL showing the user as logged in. The error only occurs when I try to log in.

Here are my routes:

Ripelist::Application.routes.draw do
  devise_for :users, path_names: { sign_in: 'login', sign_out: 'logout', sign_up: 'signup' }
  root to: 'listings#index'
  match '/sessions/user', to: 'devise/sessions#create', via: :post

  resources :users
  resources :listings
  resources :categories
  resources :sessions
end

Can anybody help?

解决方案

in your routes.rb file, try wrapping your routes inside the scope block as the error message suggests. Here is an example:

devise_scope :user do
   get "signup", to: "devise/registrations#new"
   get "login", to: "devise/sessions#new"
   get "logout", to: "devise/sessions#destroy"
end

This will give you nicely named routes.

And by the way, if you are using Rails 4, get rid of the match method. you need to specify the HTTP verb.

OBSOLETE old answer:

(Below is the old obsolete version of the code, shown for reference. Use the code above.)

devise_for :users, path_names: { sign_in: 'login', sign_out: 'logout', sign_up: 'signup' }

AND

match '/sessions/user', to: 'devise/sessions#create', via: :post
