Let's say you have a rails app and you want to build a separate admin app for it. There are at least two ways to go about this:

With a shared gem made of ActiveRecord models

The Good

• It is relatively simple to set up. You split out all you AR models into a gem. Share the gem between the app and the admin app and voila.

The Bad

require 'rubygems'
require 'active_support'
require 'pathname'
# require 'tapp'

class ToParams
  attr_reader :pathname

  def initialize(path)
    @pathname = Pathname.new path
