So when I include mount RailsAdmin::Engine => '/admin', :as => 'rails_admin' in my routes I get an error

RuntimeError: A rack application must be specified

The bundle says
* rails_admin (0.0.1 608ae86)

The routes have
devise_for :users
mount RailsAdmin::Engine => '/admin', :as => 'rails_admin'

I'm not sure why RailsAdmin wouldn't being included or can't be found in the routes? I tried included rails_admin my environment file but that didn't seem to help.

This probably isn't a specific to rails_admin issue but I can't seem to find any decent answer on stack overflow.
