attivo Admin Ruby on Rails Dashboard controller Errore

Question

Tutto ad un tratto la mia applicazione sembra aver sviluppato un errore di routing uninitialized constant DashboardController

Sono in esecuzione Rails 3.2.0 con ActiveAdmin (0.6.0) e fino ad oggi tutto sembrava sta lavorando bene

Il registro riporta il seguente errore che si verificano quando si tenta di eseguire localhost: 3000:

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

Chiunque altro ha avuto questo errore? Qualsiasi aiuto che la gente possa offrire sarebbe molto apprezzato!

Answer 1

Spostare la radice: a => yourController # indice al di sopra del ActiveAdmin.routes (auto)

Quando si esegue bundle exec rake routes vedrete yourController N ° al di sopra dell'indice cruscotto #.

Questo problema si verifica perché Dispone di 2 rotte da root (1 dal vostro e 1 da Admin attivo)

Answer 2

mi mancava file app/admin/dashboards.rb, vedi https://github.com/gregbell/active_admin#upgrading e https://raw.github.com/gregbell/active_admin/master/lib/generators/active_admin/install/templates/dashboard.rb
