在我从Rails 2.3.4升级到Rails 3.0.3之后，我又遇到了一个非常令人费解的问题。
我使用以下网址调用'show'控制器方法：
/节/ 10
我在终端
中看到了这一点开始为127.0.0.1获取“/ verse / 10” 在2011-01-27 16:17:58 -0800
VersesController处理#show 作为HTML
的诗句
* 搜索ID为在其中呈现经文/ show.html.erb 布局/应用（76.6ms）
在1006毫秒内完成200 OK（浏览次数： 125.4ms | ActiveRecord：9.8ms）
这节经文的方法非常简单：
def show
logger.debug("*** Searching for verse with ID: #{params[:id]}")
@vs = Verse.find(params[:id])
end
路线定义如下：
match '/verse/:id', :to => 'verses#show', :as => 'verse'
问题：参数ID，在这种情况下是'10'，没有被传递到控制器方法，因此抛出了404，因为params [：id]是nil。
“rake routes | grep verse”的输出如下：
verse /verse/:id(.:format）{：controller =＆gt;“verses”，：action =＆gt;“show”}
我已经花了很多年的时间，但觉得我错过了一些非常明显的东西。

如果您安装了open_id_authentication插件，则可能会干扰您的路线。
