Ruby on Rails的：设计问题

Question

我有这个意见中/职位/ index.html.erb

<% if user_signed_in? %>   
     <%= link_to('Logout', destroy_user_session_path, :method => 'delete') %> 
    <% else %> 
     <%= link_to('Login', new_user_session_path) %> 
    <% end %> 

类PostsController <的ApplicationController 的before_filter：的authenticate_user！ ....

class UsersController < ApplicationController before_filter：authenticate_user！ 结束

耙路线：

 new_user_session GET /usuarios/login(.:format)     {:action=>"new", :controller=>"devise/sessions"} 
      user_session POST /usuarios/login(.:format)     {:action=>"create", :controller=>"devise/sessions"} 
    destroy_user_session DELETE /usuarios/logout(.:format)     {:action=>"destroy", :controller=>"devise/sessions"} 
      user_password POST /usuarios/secret(.:format)     {:action=>"create", :controller=>"devise/passwords"} 
     new_user_password GET /usuarios/secret/new(.:format)    {:action=>"new", :controller=>"devise/passwords"} 
     edit_user_password GET /usuarios/secret/edit(.:format)    {:action=>"edit", :controller=>"devise/passwords"} 
         PUT /usuarios/secret(.:format)     {:action=>"update", :controller=>"devise/passwords"}

    edit_user_registration GET /usuarios/register/edit(.:format)   {:action=>"edit", :controller=>"devise/registrations"}

        posts GET /posts(.:format)       {:action=>"index", :controller=>"posts"}

       edit_post GET /posts/:id/edit(.:format)     {:action=>"edit", :controller=>"posts"} 
        post GET /posts/:id(.:format)      {:action=>"show", :controller=>"posts"} 
         PUT /posts/:id(.:format)      {:action=>"update", :controller=>"posts"} 
         DELETE /posts/:id(.:format)      {:action=>"destroy", :controller=>"posts"} 
           /posts/:id/categ(.:format)     {:controller=>"posts", :action=>"categ"} 
           /posts/:id/tag_posts(.:format)    {:controller=>"posts", :action=>"tag_posts"} 
    posts_searcharchive  /posts/searcharchive(.:format)    {:controller=>"posts", :action=>"searcharchive"} 
       categories GET /categories(.:format)      {:action=>"index", :controller=>"categories"} 
         POST /categories(.:format)      {:action=>"create", :controller=>"categories"} 
      new_category GET /categories/new(.:format)     {:action=>"new", :controller=>"categories"} 
      edit_category GET /categories/:id/edit(.:format)    {:action=>"edit", :controller=>"categories"} 
       category GET /categories/:id(.:format)     {:action=>"show", :controller=>"categories"} 
         PUT /categories/:id(.:format)     {:action=>"update", :controller=>"categories"} 
         DELETE /categories/:id(.:format)     {:action=>"destroy", :controller=>"categories"} 
       comments GET /comments(.:format)       {:action=>"index", :controller=>"comments"} 
         POST /comments(.:format)       {:action=>"create", :controller=>"comments"} 
      new_comment GET /comments/new(.:format)      {:action=>"new", :controller=>"comments"} 
      edit_comment GET /comments/:id/edit(.:format)    {:action=>"edit", :controller=>"comments"} 
       comment GET /comments/:id(.:format)      {:action=>"show", :controller=>"comments"} 
         PUT /comments/:id(.:format)      {:action=>"update", :controller=>"comments"} 
         DELETE /comments/:id(.:format)      {:action=>"destroy", :controller=>"comments"} 
       countpages GET /countpages(.:format)      {:action=>"index", :controller=>"countpages"} 
         POST /countpages(.:format)      {:action=>"create", :controller=>"countpages"} 
      new_countpage GET /countpages/new(.:format)     {:action=>"new", :controller=>"countpages"} 
      edit_countpage GET /countpages/:id/edit(.:format)    {:action=>"edit", :controller=>"countpages"} 
       countpage GET /countpages/:id(.:format)     {:action=>"show", :controller=>"countpages"} 
         PUT /countpages/:id(.:format)     {:action=>"update", :controller=>"countpages"} 
         DELETE /countpages/:id(.:format)     {:action=>"destroy", :controller=>"countpages"} 
        root  /(.:format)         {:controller=>"posts", :action=>"index"} 

在routes.rb中：

devise_for :users, :path => "usuarios", :path_names => { :sign_in => 'login', :sign_out => 'logout', :password => 'secret', :confirmation => 'verification', :unlock => 'unblock', :registration => 'register', :sign_up => 'cmon_let_me_in' } 

我得到错误：

的ActionController :: RoutingError在＃新设计/会话

显示app/views/layouts/application.html.erb，其中行＃16出现：

没有路由匹配{：控制器=>“设计/职位”}

这是根：根：到=>“帖子＃指数”，当我打http://0.0.0.0:3000，它重定向到http://0.0.0.0:3000/usuarios/login和得到这个错误，

应用程序/视图/布局/ application.html.erb：16：`_app_views_layouts_application_html_erb__647429696_90155120__982654953'

的问题是，因为你改变了缺省路由的用户：devise_for :users, :path => "usuarios",我的意思是，现在所有的路线将是_usuario_即：

<% if usuario_signed_in? %>   
     <%= link_to('Logout', destroy_usuario_session_path %> 
    <% else %>.....
