MyApplication::Application.routes.draw do
  resources :matters do
    resources :issues
  end

我收到以下路由错误：@H_502_5@

No route matches {:action=>"show",:controller=>"issues",:matter_id=>#<Matter id: 2,name: "Wilson",user_id: nil,created_at: "2011-03-23 18:19:40",updated_at: "2011-03-23 18:19:40">,:id=>nil}

我想尝试这样的道路：@H_502_5@

<%= link_to issue.content,matter_issue_path(@matter,@issue) %>

当我运行rake路线时,它显示我有路径：@H_502_5@

matter_issues GET  /matters/:matter_id/issues(.:format) {:action=>"index",:controller=>"issues"}

任何想法为什么我收到此错误？谢谢！@H_502_5@
