提示中说的很清楚了。他把你的'search'当成了params[:id]的值了。
我想问题可能是你的routes中没有添加search的route吧。看上面的信息你的events好像是用RESTFul的。
看书抄例子，要抄完整呀~~~
另外，建议下次的标题不要用“**高手进”，“重大发现***”等字样，呵呵~~题外话

routes中已经写了
------------------------------------------------------------------------------
 map.resources :events, :collection => { :search => :get }
但还是出错
是否还要写其他的东西

原本想把写的有错的程序上传的,但不知道为什么传不了.

你rake routes 看看是不有 “http://localhost:3000/events/search?q=rubyconf”的URL

好的,我试试..

如果有的话，把那条route的顺序往上调点，估计是在
route.map /:controller/:action/:id。。。啥的那条后面了吧。

C:\rubydev\ad\REST>rake routes
(in C:/rubydev/ad/REST)
    search_events GET  /events/search       {:controller=>"events", :action=>"search"}
formatted_search_events GET  /events/search.:format    {:controller=>"events", :action=>"search"}
      events GET  /events         {:controller=>"events", :action=>"index"}
   formatted_events GET  /events.:format      {:controller=>"events", :action=>"index"}
        POST /events         {:controller=>"events", :action=>"create"}
        POST /events.:format      {:controller=>"events", :action=>"create"}
     new_event GET  /events/new        {:controller=>"events", :action=>"new"}
  formatted_new_event GET  /events/new.:format     {:controller=>"events", :action=>"new"}
     edit_event GET  /events/:id/edit      {:controller=>"events", :action=>"edit"}
 formatted_edit_event GET  /events/:id/edit.:format   {:controller=>"events", :action=>"edit"}
      event GET  /events/:id        {:controller=>"events", :action=>"show"}
   formatted_event GET  /events/:id.:format     {:controller=>"events", :action=>"show"}
        PUT  /events/:id        {:controller=>"events", :action=>"update"}
        PUT  /events/:id.:format     {:controller=>"events", :action=>"update"}
        DELETE /events/:id        {:controller=>"events", :action=>"destroy"}
        DELETE /events/:id.:format     {:controller=>"events", :action=>"destroy"}
           /:controller/:action/:id
           /:controller/:action/:id.:format

rake 出来的...
有search的 action的.
这问题想了很久,就是不懂

route中
------------------------------
ActionController::Routing::Routes.draw do |map|

 map.resources :events, :collection => { :search => :get }
....................................

map我写在了第一句

看样子是没问题的呀。服务器重启过嘛？不先你把项目打包，发给我: qq:310515

在线等.... 这问题卡了2礼拜了.
