Активный администратор Ruby on rails Ошибка контроллера панели мониторинга

Внезапно в моем приложении возникла ошибка маршрутизации uninitialized constant DashboardController

Я использую Rails 3.2.0 с ActiveAdmin (0.6.0), и до сегодняшнего дня все работало нормально.

Журнал сообщает о следующей ошибке, возникающей при попытке запустить localhost: 3000:

Started GET "/" for 127.0.0.1 at 2013-04-04 18:59:21 +0100

У кого-нибудь еще была эта ошибка? Любая помощь, которую могут предложить люди, будет высоко оценена!

Переместите корень :to => yourController#index выше ActiveAdmin.routes(self)

Когда вы запустите bundle exec rake routes, вы увидите yourController#index над панелью инструментов#index.

Эта проблема возникает из-за того, что у него есть 2 маршрута к root (1 от вашего и 1 от Active Admin)

Спасибо тебе за это! Я сделал кучу других изменений в дополнение к обновлению ActiveAdmin, и, что еще хуже, у нас есть еще один контроллер в нашем приложении, который называется DashboardController. - person Michael Natkin; 20.06.2013

Мне не хватало файла app/admin/dashboards.rb , см. https://github.com/gregbell/active_admin#upgrading и https://raw.github.com/gregbell/active_admin/master/lib/generators/active_admin/install/templates/dashboard.rb
