管理命名空间访问错误 - 未初始化的常量 Model_name

Question

我正在处理管理命名空间，移动一些东西，例如用户，将资源发布到管理部分。

在 config/routes.rb 我有：

namespace :admin do        
  root :to => 'pages#home'
  #match "/" => "pages#home", :as => "index", :via => :get 
  resources  :users, :posts
end

在 app/controllers/admin/pages_controller.rb 我有：

class Admin::PagesController < Admin::ApplicationController
  def home
    @title = 'Home'
  end
end

以下是错误：（此处为完整的错误日志：http://pastebin.com/bwF1bBHz）

你们有什么想法吗？我该怎么办？

非常感谢！

Answer 1

你不应该把你的控制器文件放到

app/admin/pages_controller.rb

但要

app/controllers/admin/pages_controller.rb

同样关注视图 - 此控制器中索引操作的默认视图应放置在：

app/views/admin/pages/index.html.erb

附言您在 pastebin 上的日志与您在此处发布的不同：
