从Rails 3.1.12升级到3.2.17时，我发生了一个相当奇怪的错误。
基本上，我可以加载一次页面，但是一旦我点击刷新，我就会得到一个
AbstractController::ActionNotFound
我再次说，你错过了它。我可以加载页面，ONCE。所以我知道路线很好，但是如果我刷新完全相同的页面，我就找不到这个动作了。
这发生在每一页上。我可以查看一次，但在刷新时我无法再查看它。
修复它的方法是，要么反弹rails服务器，要么更改路由文件并保存。
路线文件是大到发布的方式，所以我在这里只使用一个页面作为例子。
该页面位于 / dashboard
路线是：
match '/dashboard', :to => 'pages#dashboard'
我点击了那个页面，它加载得很好，我再次点击它，它失败了
AbstractController::ActionNotFound at /dashboard
The action 'dashboard_pages' could not be found for PagesController
该操作被称为＆＃34;仪表板＆＃34;在页面控制器上。
我现在谷歌搜索了一段时间，它的整个＆＃34; 1视图＆＃34;令人困惑的事情。我找不到有这个问题的其他人。
任何帮助将不胜感激。

我发现了问题。
有一段代码正在打印action_name＆lt;＆lt;视图中的controller_name。在Rails 3.1中，这只是连接字符串并打印出来。在3.2中是改变请求参数。
