命名空间项的 Rails 路由错误

我们有一个 Rails 应用程序不断产生我们无法追踪的错误。 问题似乎出在路由上,但我们不确定发生了什么。 输出路由文件如下所示:

  ActionController::Routing::Routes.draw do |map|
    # Default
    map.home '', :controller => "home"

    # Admin

    map.admin_home 'admin', :controller => 'admin/admin', :action => 'index'
    map.admin_login 'admin/login', :controller => 'admin/admin', :action => 'login'
    map.admin_reminder 'admin/forgot', :controller => 'admin/admin', :action => 'reminder'
    map.namespace :admin do |admin|
      admin.resources :bookings,
        :collection => {
          :archive => :get, :reports => :get, :calendar => :get,
          :step_1 => :any, :step_1a => :any, :step_2 => :any, :step_3 => :any, :confirmation => :any }
      admin.resources :events,
        :member => { :status => :get }
      admin.resources :blogs,
        :collection => { :archive => :get }
      admin.resources :blog_replies,
        :member => { :publish => :get }
      admin.resources :minutes,
        :collection => { :archive => :get }
      admin.resources :businesses
      admin.resources :business_categories
      admin.resources :users
      admin.resources :pricings
      admin.backups 'backups', :controller => 'admin/backups'
      admin.download_backup 'backups/download', :controller => 'admin/backups', :action => 'download'
    end
    map.admin 'admin/:action', :controller => 'admin/admin'

    map.connect 'members', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'members/login', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'account', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'account/login', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'home', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'home/login', :controller => 'admin/admin', :action => 'redirect_to_index'

    map.blog 'blog/:permalink', :controller => 'blogs', :action => 'show'
    map.connect 'blog/:id', :controller => 'blogs', :action => 'show'
    map.connect 'book-online', :controller => 'bookings', :action => 'step_1'
    map.connect 'book-online/:action', :controller => 'bookings'
    # Defaults
    map.connect ':controller/:action/:id'
    map.connect "*anything", :controller => "public", :action => "unknown_request"
  end

我们在 app/controllers 中有一组公共控制器,在 app/controllers/admin 中有一组管理控制器。 我们不断看到的问题是,当用户访问 admin/bookings、admin/bookings/step_1 或 admin/events 等网址时。 有时 url 工作正常,但有时我可以从日志文件中看到发生类似以下情况:

ActionController::UnknownAction (No action responded to index):

其他时候我们会得到类似的信息:

Processing EventsController#index (for [filtered] at 2009-01-21 10:54:38) [GET]
Session ID: [filtered]
Parameters: {"action"=>"index", "controller"=>"admin/events"}
Rendering template within layouts/public
Rendering events/index
Completed in 0.00863 (115 reqs/sec) | Rendering: 0.00338 (39%) | DB: 0.00000 (0%) | 200 OK [http://www.gresfordtrust.org/admin/events]

从最后一个示例中,您可以看到请求的 url 是 admin/events< /code> 应该命中 Admin::EventsController 中的 #index,但它却在 EventsController< 中呈现 #index 操作/代码>。

我们使用 Rails 2.0.2 运行该应用程序。

We've got a rails app that keeps producing an error that we can't track down. The problem seems to lie with the routing but we're not sure what is happening. Out routes file looks like:

  ActionController::Routing::Routes.draw do |map|
    # Default
    map.home '', :controller => "home"

    # Admin

    map.admin_home 'admin', :controller => 'admin/admin', :action => 'index'
    map.admin_login 'admin/login', :controller => 'admin/admin', :action => 'login'
    map.admin_reminder 'admin/forgot', :controller => 'admin/admin', :action => 'reminder'
    map.namespace :admin do |admin|
      admin.resources :bookings,
        :collection => {
          :archive => :get, :reports => :get, :calendar => :get,
          :step_1 => :any, :step_1a => :any, :step_2 => :any, :step_3 => :any, :confirmation => :any }
      admin.resources :events,
        :member => { :status => :get }
      admin.resources :blogs,
        :collection => { :archive => :get }
      admin.resources :blog_replies,
        :member => { :publish => :get }
      admin.resources :minutes,
        :collection => { :archive => :get }
      admin.resources :businesses
      admin.resources :business_categories
      admin.resources :users
      admin.resources :pricings
      admin.backups 'backups', :controller => 'admin/backups'
      admin.download_backup 'backups/download', :controller => 'admin/backups', :action => 'download'
    end
    map.admin 'admin/:action', :controller => 'admin/admin'

    map.connect 'members', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'members/login', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'account', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'account/login', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'home', :controller => 'admin/admin', :action => 'redirect_to_index'
    map.connect 'home/login', :controller => 'admin/admin', :action => 'redirect_to_index'

    map.blog 'blog/:permalink', :controller => 'blogs', :action => 'show'
    map.connect 'blog/:id', :controller => 'blogs', :action => 'show'
    map.connect 'book-online', :controller => 'bookings', :action => 'step_1'
    map.connect 'book-online/:action', :controller => 'bookings'
    # Defaults
    map.connect ':controller/:action/:id'
    map.connect "*anything", :controller => "public", :action => "unknown_request"
  end

We have a set of public controllers in app/controllers and a set of admin controllers in app/controllers/admin. The issue we keep seeing is when a user goes to a url like admin/bookings, admin/bookings/step_1 or admin/events. Sometimes the urls work perfectly but other times I can see from the log file that something like the following happens:

ActionController::UnknownAction (No action responded to index):

Other times we'll get something like:

Processing EventsController#index (for [filtered] at 2009-01-21 10:54:38) [GET]
Session ID: [filtered]
Parameters: {"action"=>"index", "controller"=>"admin/events"}
Rendering template within layouts/public
Rendering events/index
Completed in 0.00863 (115 reqs/sec) | Rendering: 0.00338 (39%) | DB: 0.00000 (0%) | 200 OK [http://www.gresfordtrust.org/admin/events]

from the last example you can see that the url requested was admin/events which should have hit the #index in Admin::EventsController but instead it renders the #index action in EventsController.

We're running the app with Rails 2.0.2.

您没有为 EventsController 配置路由,因此发生错误是因为某些请求落入默认路由 map.connect ':controller/:action/:id'

发生这种情况是因为某人/某物正在发送未为您的 AdminEventsController 配置的 HTTP 方法的请求。 您的 admin.resources :events, :member => {:状态=> :get } 将匹配以下请求:

GET /admin/events
GET /admin/events/<id>
GET /admin/events/<id>/status
POST /admin/events
PUT /admin/events/<id>
DELETE /admin/events/<id>

任何其他请求都会进入默认路由。 因此,如果您在此控制器上看到这些 ActionController::UnknownAction,请查找使用错误 HTTP 方法的请求。

奇怪的日志消息的来源几乎肯定是这样的请求:

GET /admin/events/index

解决方案是完全摆脱该默认路由,并确保为所有资源添加 resource[s] 路由控制器位于正确的位置。

You don't have a configured route for EventsController, so your error is happening because some request is falling down to the default route, map.connect ':controller/:action/:id'
.

This is happening because someone/something is sending a request of an HTTP method that isn't configured for your AdminEventsController. Your admin.resources :events, :member => { :status => :get } will match the following requests:

GET /admin/events
GET /admin/events/<id>
GET /admin/events/<id>/status
POST /admin/events
PUT /admin/events/<id>
DELETE /admin/events/<id>

Anything else would fall through to the default route. So if you're seeing those ActionController::UnknownAction on this controller look for requests that are using the wrong HTTP method.

The source of your bizarre log message is almost certainly a request that was something like this:

GET /admin/events/index

The solution is to get rid of that default route entirely and ensure you're adding resource[s] routes for all the controllers in the right place.
