ruby-on-rails - 设计 - 在子域上登录

Question

我在具有多个子域和多个模式的 rails 应用程序中使用设计 gem。

每个子域都由 Controller 处理，在 application_controller.rb 上看起来像这样:

def load_subdomain
    @account = Account.find_by_subdomain!(request.subdomain)
end

def after_sign_in_path_for(resource)
    #admin login in domain
    if resource.is_a?(admin) 
      admin_path
    #user login in subdomain
    elsif resource.is_a?(user)
      subdomain_root_path
    else
      super
    end    
  end

在routes.rb上

    match '/' => 'subdomains#index', :constraints => { :subdomain => /.+/ }, :as => :subdomain_root

devise_for :users, :skip => [:sessions, :registrations]

  devise_scope :user do
    get '/login/user' => 'sesusers#new', :as => :new_session_user
    post '/signin/user' => 'sesusers#create', :as => :user_session
    delete '/logout/user' => 'sesusers#destroy', :as => :destroy_user_session
    post '/send/user' => 'passwordusers#create', :as => :passwordusers_create
    get '/change_password/user' => 'passwordusers#edit', :as => :passwordusers_edit
    put '/change/user' =>  'passwordusers#update', :as => :passwordusers_update
  end

这导致每个子域有多个 sign_in url。

subdomain1.lvh.me:3000/login/user
subdomain2.lvh.me:3000/login/user
subdomain3.lvh.me:3000/login/user
...
...
etc

在 sesusers_controller.rb 上

class SesusersController < Devise::SessionsController
  include Tenantable::Schema::Controller
  before_filter :load_subdomain

  def new
    super
  end

  def create
    logger.info "Logged in"
    super
  end

  def destroy
    logger.info "Logout success"
    super
  end
end

当我尝试登录时，成功登录并重定向到 subdomain_root_path

看，登录成功.. 查看子域

<div class="pull-right">
     <div class="btn-group">
         <% if user_signed_in? %>
            <%= link_to current_user.name, '#', { :class => 'btn btn-danger dropdown-toggle', 'data-toggle' => 'dropdown' } %>
                <ul class="dropdown-menu">
                  <li> <%= link_to "Dashboard", '#', 'style' =>"color:#fff" %></li>
                </ul>
         <% else %>
            <%= link_to ('<i class="icon-lock icon-white"></i>').html_safe + " Login" +(' <span class="caret"></span>').html_safe , '#', { :class => 'btn btn-danger dropdown-toggle', 'data-toggle' => 'dropdown' } %>
                <ul class="dropdown-menu">
                   <li><%= link_to "User", new_session_user_path, 'style' =>"color:#000" %></li>

                </ul>
         <% end %>
    </div>
</div>

但在查看子域 current_user.name不显示，只出现登录按钮。

有人能帮我吗？

谢谢/

为此，您只需要在子域之间共享用户 session ，以便多个子域可以继续一个 session 。

您应该修改 session_store.rb文件初始化为，

  DemoApp::Application.config.session_store :cookie_store, key: '_jcrop_app_session', domain: ".maindomain.com"

添加域将工作并小心使用子域所需的最后一个前导“ . ”(句点)。
