ruby-on-rails - 设计身份验证。宝石退出不像我预期的那样工作

Question

我将设计集成到我的应用程序中，这里是我认为对问题很重要的当前代码。

这是我的退出链接

<nav class="round">
        <ul>
            <li>
                <%= link_to "Home", root_path%>
            </li>
            <li>
                <%= link_to "Help (learn Bunch-It)", help_path %>
            </li>
            <% if signed_in? %>
            <li>
                <%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
            </li>
            <li>
                <%= link_to "Profile "+current_user.user_name, user_path(current_user), :method => :delete %>
            </li>
            <%else%>
            <li>
                <%= link_to "Sign in", new_user_session_path %>
            </li>
            <%end%>
        </ul>
    </nav>

然后路由.rb

devise_for :users

  #get "sessions/new"

  #get "session/new"

  resources :users
  #resources :sessions, :only => [:new, :create, :destroy]

  #get "users/new"

  get "pages/home"

  get "pages/contact"

  get "pages/about"

  get "pages/help"

  get "results/result"

  get 'tree/insertResult' => 'tree#insertResult'

  get "tree/deleteFolder" => 'tree#deleteFolder'

  get "tree/createFolder" => 'tree#createFolder'

  get "tree/deleteResult" => 'tree#deleteResult'

  match '/results' , :to => 'results#result'
  match '/contact' , :to => 'pages#contact'
  match '/about' , :to => 'pages#about'
  match '/help' , :to => 'pages#help'
  match '/home_index', :to => 'pages#home'
  #match '/signin', :to => 'sessions#new'
  #match '/signout', :to => 'sessions#destroy'
  root :to => 'pages#home'

这是我的控制器功能。主页

class PagesController < ApplicationController

  def home
    @title = "Home"
    session[:return_to] = request.fullpath
    @page = request.path
    puts "Welcome home page"
  end
...

最后这是我的个人资料网站控制器

class UsersController < ApplicationController
  before_filter :authenticate_user!, :only => :token

  def index

  end
  def token

  end
  def show
    @title = current_user.user_name
    @haveQuery = false
    if @newest_query = findNewestQuery
      @common_query = commonQuery
      @haveQuery = true
    else
      @haveQuery = false
    end
  end

问题是，当我按下退出我的应用程序时，只需刷新个人资料网站或将我定向到个人资料网站，如果我目前在不同的网站上。但是我想被定向到我的应用程序的主页而不是个人资料页面。我做了我能想到但无法解决的任何事情。有什么小想法是送给我的礼物吗？:)

我的 rails 3.2 应用程序也遇到了同样的问题。我发现问题出在我的路由文件上。如果您仍然遇到问题，我建议您打开设计宝石并四处寻找。

  devise_for :users, :controllers => {:sessions => "user/sessions", :registrations => "user/registrations"}
  devise_scope :user do
    get '/login' => 'devise/sessions#new'
    get '/logout' => 'devise/sessions#destroy'
  end
  resources :user, :controller => "user"
  root :to => "home#index"

在视图中是这样的

<%= link_to 'Logout', logout_path, :method => :delete %>

用户模型看起来像这样

    class User
      # Include default devise modules. Others available are:
      # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
      devise :database_authenticatable, :registerable,
             :recoverable, :rememberable, :trackable, :validatable

      # Validations.
      validates_presence_of :email, :first_name, :last_name, :password
      validates_uniqueness_of :email, :case_sensitive => false
      attr_accessible :first_name, :last_name, :email, :password, :password_confirmation, :remember_me


     end

编辑：检查这些东西的好方法

                         DELETE /user/:id(.:format)            user#destroy
                    root        /                              home#index

这也是我的控制器，所以我们大部分时间都在同一页面上。

class User::SessionsController < Devise::SessionsController

  def new
    super
  end

  def create
     resource = warden.authenticate!(:scope => resource_name, :recall => "#{controller_path}#new")
     if is_navigational_format?
       if resource.sign_in_count == 1
         set_flash_message(:notice, :signed_in_first_time)
       else
         set_flash_message(:notice, :signed_in)
       end
     end
     sign_in(resource_name, resource)
     respond_with resource, :location => redirect_location(resource_name, resource)
   end  
end

class User::RegistrationsController < Devise::RegistrationsController

  def new
      super # no customization, simply call the devise implementation
    end

    def create
      begin
        super # this calls Devise::RegistrationsController#create
      rescue MyApp::Error => e
        e.errors.each { |error| resource.errors.add :base, error }
        clean_up_passwords(resource)
        respond_with_navigational(resource) { render_with_scope :new }
      end
    end

    def update
      super # no customization, simply call the devise implementation 
    end

    protected

    def after_sign_up_path_for(resource)
      new_user_session_path
    end

    def after_inactive_sign_up_path_for(resource)
      new_user_session_path
    end
end
