重定向适用于登录但不适用于注销

说明

我正在使用带有Ruby on Rails webapp的devise gem，并按照本教程介绍如何在用户登录和注销后将用户重定向回上一页。 问题是，代码似乎适用于登录部分，但注销总是将用户重定向到root_path。

题

当我完全按照教程，并且重定向适用于一个，我是否错过了一个错字或者其他地方的代码是否覆盖了这段代码？

使用的版本

Ruby：ruby 2.2.1p85（2015-02-26修订版49769）[x86_64-darwin14]

Rails：Rails 4.2.0

设计：3.4.1

码

应用控制器：

## app/controllers/application_controller.rb class ApplicationController < ActionController::Base # Prevent CSRF attacks by raising an exception. # For APIs, you may want to use :null_session instead. protect_from_forgery with: :exception after_filter :store_location before_action :configure_permitted_parameters, if: :devise_controller? def store_location # store last url - this is needed for post-login redirect to whatever the user last visited. return unless request.get? if (request.path != "/login" && request.path != "/logout" && request.path != "/register" && request.path != "/users/password/" && request.path != "/users/password/new" && request.path != "/users/password/edit" && request.path != "/users/confirmation" && request.path != "/profile/" && request.path != "/profile/edit" && request.path != "/admin/dashboard" && request.path != "/admin/moderate_users" && request.path != "/admin/moderate_events" && request.path != "/admin/moderate_event_items" && request.path != "/admin/moderate_companies" && request.path != "/admin/moderate_locations" && request.path != "/admin/moderate_stories" && !request.xhr?) # don't store ajax calls session[:previous_url] = request.fullpath end end protected def after_sign_in_path_for(resource) session[:previous_url] || root_path end def after_sign_out_path_for(resource) session[:previous_url] || root_path end end 

路由文件：

 ## app/config/routes.rb Rails.application.routes.draw do ## Site's Root Route root 'pages#home' ## Static Page Routes get 'home' => 'pages#home' get 'about' => 'pages#about' get 'contact' => 'pages#contact' get 'privacy' => 'pages#privacy' get 'sitemap' => 'pages#sitemap' ## Administrative Routes get 'admin/dashboard' get 'admin/moderate_users' get 'admin/moderate_events' get 'admin/moderate_event_items' get 'admin/moderate_companies' get 'admin/moderate_locations' get 'admin/moderate_stories' ## Customed Devise Routes devise_for :users, :skip => [:sessions, :registrations] devise_scope :user do get "login", to: "devise/sessions#new", as: :new_user_session post "login", to: "devise/sessions#create", as: :user_session delete "logout", to: "devise/sessions#destroy", as: :destroy_user_session get "register", to: "devise/registrations#new", as: :new_user_registration post "register", to: "devise/registrations#create", as: :user_registration get "account/delete", to: "devise/registrations#cancel", as: :cancel_user_registration get "user/profile/edit", to: "devise/registrations#edit", as: :edit_user_registration patch "user", to: "devise/registrations#update" put "user", to: "devise/registrations#update" put "register", to: "devise/registrations#update" delete "user/delete", to: "devise/registrations#destrony" get "user/profile", to: 'devise/registrations#edit', as: :user_root end end 

ApplicationHelper文件中没有任何后果。

预先感谢您的帮助。

Answer 1

我相信你的会话变量在注销时被设置为nil，因此重定向到根路径。

尝试使用以下设置保持会话范围与注销无关。

 config.sign_out_all_scopes = false 

在devise.rb文件中获取所需的行为

ref： 停止设置清算

您可以自定义after_sign_out_path_for(resource)如果您想在用户注销后将用户重定向回上一页，如下所示

 def after_sign_out_path_for(resource) request.referrer end
