【问题描述】：
我在从 Rails 3.1.12 升级到 3.2.17 时发生了一个相当奇怪的错误。
基本上，我可以加载一个页面，但只要我点击刷新，我就会得到一个
AbstractController::ActionNotFound
我会再说一遍，以防你错过它。我可以加载页面，一次。所以我知道路线很好，但是如果我刷新完全相同的页面，我会找不到这个动作。
这发生在每一页上。我可以查看一次，但刷新后我无法再次查看。
修复它的方法是弹回 Rails 服务器或更改路由文件并保存。
路由文件太大了，所以我在这里只使用一个页面作为示例。
该页面位于 /dashboard
路线是：
match '/dashboard', :to => 'pages#dashboard'
我点击了那个页面，它加载正常，我再次点击它，它失败了
AbstractController::ActionNotFound at /dashboard
The action 'dashboard_pages' could not be found for PagesController
该操作在页面控制器上称为“仪表板”。
我已经在谷歌上搜索了一段时间，它的整个“1 视图”事情一直令人困惑。我找不到其他有这个问题的人。
任何帮助将不胜感激。
这是堆栈跟踪：

【问题讨论】：
-
您能否通过将其升级到：
get 'dashboard', to: 'pages#dashboard'来尝试新的路由样式（另请查看路由导轨指南：guides.rubyonrails.org/routing.html） -
嗨，Taryn，同样的问题。它会运行一次，但不会再次运行。
-
好的。好吧，值得测试 :) 所以现在 - 你的 pages_controller 和他查看仪表板的内容是什么？您是否在某个地方引用了仪表板路径？ （我猜不是因为它适用于所有观点......但它可能会有所帮助）。另外 - 你有完整的堆栈跟踪吗？
-
我会用堆栈跟踪更新帖子
-
另外值得一提的是，当这个错误发生时，它甚至还没有命中我的代码。我可以在我的应用程序控制器的第一行代码上放置一个断点，它不会命中它。 （您可以从堆栈跟踪中看到这一点）因此，我的视图中的代码或控制器并不是看起来的问题。
