All of a sudden my app seems to have developed a routing error uninitialized constant DashboardController

I am running Rails 3.2.0 with ActiveAdmin (0.6.0) and up until today everything seemed to be working fine.

The log is reporting the following error which occuring when trying to run localhost:3000:

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

Has anyone else had this error? Any help people can offer would be much appreciated!

Move the root :to => yourController#index above the ActiveAdmin.routes(self)

When you run bundle exec rake routes you will see yourController#index above dashboard#index.

That problem occurs because It has 2 routes to root (1 from your and 1 from Active Admin)

Thank you for this! I had made a bunch of other changes in addition to upgrading ActiveAdmin, and to makes matters worse, we happen to have another controller in our app called DashboardController.. so I totally thought it was something I hosed.

I was missing file app/admin/dashboards.rb , see https://github.com/gregbell/active_admin#upgrading and https://raw.github.com/gregbell/active_admin/master/lib/generators/active_admin/install/templates/dashboard.rb
