Using rails_admin without devise

Having a buckload of code to authorize users on your application is something you may like or not. Speaking for myself I hate it. But I still love rails_admin, here's how you install it without devise. Thanks to phoet for providing the hints in the gist I have forked from.

Add RailsAdmin to your Gemfile

do NOT add devise

gem "rails_admin", :git => "git://github.com/sferik/rails_admin.git"
