Administrador activo Ruby on rails Error del controlador del cuadro de mandos

Question

De repente, mi aplicación parece haber desarrollado un error de enrutamiento sin uninitialized constant DashboardController

Estoy ejecutando Rails 3.2.0 con ActiveAdmin (0.6.0) y hasta hoy todo parecía funcionar bien.

El registro informa del siguiente error que se produce al intentar ejecutar localhost: 3000:

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

¿Alguien más ha tenido este error? ¡Cualquier ayuda que la gente pueda ofrecer sería muy apreciada!

Answer 1

Me faltaba la aplicación / admin / dashboards.rb, vea https://github.com/gregbell/active_admin#upgrading y https://raw.github.com/gregbell/active_admin/master/lib/generators/active_admin/install/templates/dashboard.rb

Answer 2

Mueva la raíz: a => suControlador # índice sobre ActiveAdmin.routes (self)

Cuando ejecute las bundle exec rake routes , verá su Controlador # índice arriba del tablero # índice.

Ese problema se produce porque tiene 2 rutas a la raíz (1 de usted y 1 de Active Admin)
