Ruby on rails Active Admin Ruby on rails仪表板控制器错误

突然间，我的应用程序似乎出现了路由错误

未初始化的常量Dashboard Controller

我正在用ActiveAdmin（0.6.0）运行Rails 3.2.0，直到今天，一切都运行得很好

日志报告在尝试运行localhost:3000时发生以下错误：

还有其他人犯过这个错误吗？任何人能提供的帮助都将不胜感激

将root:to=>yourController#索引移到ActiveAdmin.routes（self）上方

当您运行

bundle exec rake routes

时，您将在仪表板上看到控制器索引

---

出现此问题是因为它有两条到根目录的路由（一条来自您的，一条来自活动管理员）

我缺少app/Admin/dashboards.rb文件，请参阅，谢谢！除了升级ActiveAdmin之外，我还做了一系列其他更改，更糟糕的是，我们的应用程序中还有一个名为DashboardController的控制器。。所以我完全认为这是我用水管冲洗过的东西。
