Ruby on rails RoR控制器返回404错误

你好，这是我的问题

所有控制器在浏览器中始终返回404错误，但在日志中：

Processing PostController#index (for myip at 2013-02-01 13:33:02) [GET]
Rendering post/index
Completed in 2ms (View: 1, DB: 0) | 200 OK [http://site.com/]

和文件/公共加载罚款。My routes.rb：

map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'

---

希望您的帮助。

您的路线意味着您需要始终匹配以下

/controller/action/id

或

/controller/action/id.format

。您应该使用类似于为新rails项目生成的括号记下关于为什么不应该这样做的评论

# This is a legacy wild controller route that's not recommended for RESTful  applications.
# Note: This route will make all actions in every controller accessible via GET requests.
# match ':controller(/:action(/:id))(.:format)'

---

让控制器工作的一个简单方法是在路由中添加资源。这将映射所有控制器方法

# app/controllers/controllernames_controller.rb
class ControllernamesController < ApplicationController
  def index
  end

  # and other methods you want...
end

# config/routes.rb
MyApp::Application.routes.draw do
   resources :controllername
end

如果您使用Rails提供的RESTful脚手架，那么您可以：

<%= link_to "whatever_your_like_to_name", new_controllername_path %>
# or
<%= link_to "whatever_your_like_to_name", edit_controllername_path(controllername) %>
# or 
etc...

在这种情况下，视图文件中的链接将是

<%= link_to "whatever_you_like_to_name", whatever_you_want_path %>

---

现在我有：

ActionController:：RoutingError（没有路由匹配）/post/index“

我也尝试过：

map.connect'post/index'，：controller=>'post'，：action=>'index'

但浏览器中的404和日志中的200是一样的。

# config/routes.rb
MyApp::Application.routes.draw do
   get 'controllernames/methodname', to: 'controllernames#methodname', as: "whatever_you_want"
end

<%= link_to "whatever_you_like_to_name", whatever_you_want_path %>
