Rails initializer for using ActiveAdmin with Sass on Heroku

active_admin_heroku.rb

if Rails.env.production?
  require 'fileutils'
  FileUtils.mkdir_p(Rails.root.join("tmp", "stylesheets", "admin"))

  template_path_one = "#{Gem.loaded_specs['activeadmin'].full_gem_path}/app/assets/stylesheets"
  template_path_two = "#{Gem.loaded_specs['activeadmin'].full_gem_path}/lib/active_admin/sass"
  old_compile_path = "#{Rails.root}/public/stylesheets/admin"
  new_compile_path = "#{Rails.root}/tmp/stylesheets/admin"

  Sass::Plugin::remove_template_location template_path_one
  Sass::Plugin::add_template_location template_path_one, new_compile_path

  Sass::Plugin::remove_template_location template_path_two
  Sass::Plugin::add_template_location template_path_two, new_compile_path
end

Works for me. Thanks for contributing!

Revision 241545 of this gist is for version 5b534e18 of ActiveAdmin master. Use gist revision d7b763 for ActiveAdmin version 0.2.2.

i used this gist together with http://devcenter.heroku.com/articles/using-sass

problem solved.

Thanks, this fixed for me, too.

Does this error look familiar? I tried this patch to no avail.
