重定向適用於登錄而不是註銷

Question

說明

我使用了Ruby on Rails的web應用程序的色器件寶石並按照本教程就如何處理這些登錄和退出之後將用戶重定向回他們以前的頁面。問題是，代碼似乎適用於登錄部分，但註銷始終將用戶重定向到root_path。

問題

正如我跟着教程完全相同，並且重定向工程之一，我錯過了一個錯字，還是有代碼的其他地方被改寫這個代碼？

版本使用

紅寶石：紅寶石2.2.1p85（2015年2月26日修訂版49769）[x86_64的-darwin14]

的Rails：Rails的4.2.0

設計：3.4.1

代碼

應用控制器：

## 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 != "https://stackoverflow.com/users/password/" && 
     request.path != "https://stackoverflow.com/users/password/new" && 
     request.path != "https://stackoverflow.com/users/password/edit" && 
     request.path != "https://stackoverflow.com/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：後果在ApplicationHelper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 

沒有。

非常感謝您的幫助。

Answer 1

我相信你的會話變量被設置爲在註銷爲零，因此重定向到根路徑。

請嘗試以下設置以保持與註銷無關的會話範圍。

config.sign_out_all_scopes = false 

在devise.rb文件

以獲得所需的行爲

裁判：Stop Devise from clearing session

Answer 2

您可以自定義after_sign_out_path_for(resource)如果您想將用戶重定向回他們以前的網頁，他們註銷等之後，下面

def after_sign_out_path_for(resource) 
    request.referrer 
end
