Rails 3.0.0 RC ActionController :: RoutingError“没有路由匹配”

Question

有一个工作的应用程序与Rails 3.0.0beta4和刚刚更新到RC。得到一个新的奇怪的错误。出于某种原因，当我尝试：

<%= link_to "test", user %> 

用户路由作为资源：用户但它抱怨没有路线“行动=>消灭”尽管我甚至试图链接来破坏：

ActionController::RoutingError in Main#index 
    No route matches {:action=>"destroy", :controller=>"users", :id=>#<User...>} 

对于参考我使用 红宝石1.8.7（2009-06-12 PATCHLEVEL 174）[万向darwin10.0]

路线很简单：

resources :users 

运行rake路线返回正确的东西：

      GET /users/:id(.:format)        {:controller=>"users", :action=>"show"} 
          PUT /users/:id(.:format)        {:controller=>"users", :action=>"update"} 
         user DELETE /users/:id(.:format)        {:controller=>"users", :action=>"destroy"} 
       edit_user GET /users/:id/edit(.:format)       {:controller=>"users", :action=>"edit"} 

我生成与脚手架testrails应用程序，为用户和它工作得很好，所以一定有什么东西在这里全部跟踪。我很难...

难道是从这些提交？ http://github.com/rails/rails/commit/a1e795f554e07476f1084a0c76cb8b033d1d0b0c

帮助非常感谢！

Answer 1

好吧继承人的交易。我调查了相应的代码，它是由两件事引起的。这个问题实际上是因为我有我的to_param设置如下：

def to_param 
    id + '/' + title.parameterize 
end 

我需要保持与非Rails应用程序旧网址的兼容性，因此“/”而不是通常的 - 。

的解决方法是用“％2F”

相关承诺，以取代“/”：http://github.com/rails/rails/commit/622092d33e8d326217ab1ed6138e2c572c95b8ba

Answer 2

您遇到的问题是，“/”是一个航线分离，所以为了匹配你需要你的路线，看起来像

match 'users/:id/:slug', :to=>"users#show" 

要么，或逃避“/”到“％2F”如你所说

Answer 3

我尝试这样做，在Rails 3的工作对我来说：

match "/:login" => "users#show_by_login", :as => 'show_user', :constraints => {:login => /.*/}
