Active Admin Ruby on rails Dashboard Controller Error
突然间，我的应用程序似乎已经开发了一个路由错误uninitialized constant DashboardController
我正在使用ActiveAdmin（0.6.0）运行Rails 3.2.0，直到今天一切似乎都运行正常。
日志报告在尝试运行localhost：3000时发生以下错误：

有没有其他人有这个错误？ 人们可以提供的任何帮助将非常感谢！
移动root：to => yourController #index，高于ActiveAdmin.routes（self）
当您运行bundle exec rake routes您将在控制台#index上方看到yourController #index。
出现此问题的原因是它有2条到root的路由（1个来自您的，1个来自Active Admin）
我缺少文件app / admin / dashboards.rb，请参阅https://github.com/gregbell/active_admin#upgrading和https://raw.github.com/gregbell/active_admin/master/lib/generators/active_admin/install /templates/dashboard.rb
