用Devise登录后出现奇怪的重定向 [英] Weird redirect after login with Devise

问题描述

我有使用Devise的这个应用程序，登录后，用户被重定向到一个空白页面，路径为 /users/sign_in.user 。

为什么Devise重定向到此路径？这是我得到的日志条目：

 在2011-11-开始POST/users/sign_in.user为127.0.0.1参数：{utf8=>✓，authenticity_token=>ukqyLFgApCSybuIlVynPwj / xgdI / WuHLxoFxOsY4wgQ =，user=> {email=>[e-mail]，password=>[FILTERED]，remember_me=>0}，提交=>Entrar} 
用户加载（1.8ms）SELECT`users`。* FROM`users` WHERE`users`.`email` ='[e-mail]'LIMIT 1 
（0.2ms）BEGIN 
（1.0ms）UPDATE`users` SET`last_sign_in_at` ='2011-11-09 18:47:04'，`current_sign_in_at` ='2011-11-10 17： 56:04'，`sign_in_count` = 14，`updated_at` ='2011-11-10 17:56:04'WHERE`users`.`id` = 1 
（0.3ms）COMMIT 
完成406在112ms不可接受
  

这是我的完整的 routes.rb 文件：

  MyApp :: Application.routes.draw 
 root：to => site＃home
 match'biblioteca'=> 'site＃library'，：as => ：library 
 
 devise_for：users，：controllers => {：sessions => users / sessions} 
 devise_for：admin_users，ActiveAdmin :: Devise.config 
 
 ActiveAdmin.routes（self）
 
资源：cursos 
资源：matriculas 
资源：modulo_statuses 
 end 
  

我尝试使用 after_sign_in_path_for in ApplicationController ：

  def after_sign_in_path_for（resource_or_scope）
 Rails.logger.info***** LOGGED IN，GOING TO＃{root_path}
 root_path 
 end 
  

但日志条目甚至不会显示。

有没有人有什么想法这个事情发生了吗？

解决方案

这可能是因为这样的东西被调用： user_session_path（user） ，实际上不需要用户作为参数，所以Rails将其视为格式。在您的登录视图中，这可能是错误的 form_for 调用。 after_sign_in_path_for 没有被调用，因为Rails没有考虑给定的URL一个有效的请求（这就是为什么响应是406可以接受的）。

I have this application where I use Devise and, after login the user is redirected to a blank page with the path /users/sign_in.user.

Why is Devise redirecting to this path? Here's the log entry I get:

Started POST "/users/sign_in.user" for 127.0.0.1 at 2011-11-10 15:56:03 -0200
  Processing by Users::SessionsController#create as

   (0.3ms)  COMMIT
Completed 406 Not Acceptable in 112ms

Here's my complete routes.rb file:

MyApp::Application.routes.draw do
  root :to => "site#home"
  match 'biblioteca' => 'site#library', :as => :library

  devise_for :users, :controllers => { :sessions => "users/sessions" }
  devise_for :admin_users, ActiveAdmin::Devise.config

  ActiveAdmin.routes(self)

  resources :cursos
  resources :matriculas
  resources :modulo_statuses
end

I tried using after_sign_in_path_for in ApplicationController:

def after_sign_in_path_for(resource_or_scope)
  Rails.logger.info "***** LOGGED IN, GOING TO #{root_path}"
  root_path
end

But the log entry doesn't even appear.

Does anyone have any idea why this happens?

解决方案

This is probably happening because something like this is being called: user_session_path(user) and you actually don't need the user as argument, so Rails treats it as the format. This is likely wrong in the form_for call in your sign in view. after_sign_in_path_for is not being called because Rails is not considering the given URL a valid request (that's why the response is 406 acceptable).
