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.
do NOT add devise
gem "rails_admin", :git => "git://github.com/sferik/rails_admin.git"
It works and just does not install devise.
You may also want to
$ rm config/locales/devise*.
require "rails_admin/application_controller" module RailsAdmin class ApplicationController < ::ApplicationController before_filter :is_admin? private def is_admin? if current_user.nil? || !current_user.admin? head(:forbidden) false end end end end
