Ruby on rails 3 Ruby 1.8.7/Rails 3路由：控制器#索引一直试图呈现控制器#显示

我敢肯定，我只是通过发布这篇文章来增加大量现有的路由错误问题，但如果我在过去几天没有成功地解决这个问题，我就不会发布这篇文章。我目前正在经历合并两个rails应用程序的过程，到目前为止，有些东西可以工作，有些东西不行。目前，我正在尝试让应用程序B的路由在应用程序A中工作。它们都运行在rails 3之外，并且都可以作为独立应用程序正常工作。我想，如果我简单地将路由从应用程序B复制并粘贴到应用程序A中，一切都会很好地工作，但情况似乎并非如此

目前，这是我的Routes.rb文件，我正在尝试使用以下url显示论坛控制器的索引页：

将生成以下错误消息：

路由错误

没有路由匹配{:action=>“show”，:controller=>“forums”}

这是我在执行rake routes后的routes文件：

另一件需要注意的事情是，事实上，我拥有所有必需的控制器/视图，而且据我所知，没有拼写错误

有没有想过是什么导致了这些错误？我多次尝试重新启动服务器，但没有成功。

在我试图访问的索引页上，我有一个指向我论坛的show action的链接。该链接没有使用正确的href url，因此从我的rake路由中显示的内容进行了抽象。我只需要将url替换为

论坛路径（论坛对象）

引用不能用于大量代码。请注意，我准备了一个截图，但我没有足够高的代表性发布截图：/
