Fixes an issue with AwesomePrint and ActiveRecord 3 abstract models (https://github.com/michaeldv/awesome_print/pull/147). Drop it in `~/.irbrc`

irbrc.rb

# Work around for https://github.com/michaeldv/awesome_print/pull/147
AwesomePrint::ActiveRecord.send :include, Module.new {
  def awesome_active_record_class_with_fix(object)
    return awesome_class(object) if object.respond_to?(:abstract_class?) && object.abstract_class?
    super(object)
  end

  def self.included(base)
    base.class_eval do
      alias_method :awesome_active_record_class_without_fix, :awesome_active_record_class
      alias_method :awesome_active_record_class, :awesome_active_record_class_with_fix
    end
  end
}
