Changes in this Fork
Converted to Gem ported by C. Jason Harrelson (midas)
This plugin for ActiveRecord makes the “ID” field into a URL-safe GUID It is a mashup by Andy Singleton <email@example.com> that includes
the UUID class from Bob Aman.
the plugin skeleton from Demetrius Nunes
the 22 character URL-safe format from Andy Singleton
You can get standard 36 char UUID formats instead TODO: Auto-detect a character ID field and use a GUID in this case (DRY principle)
It has been extended by Brian Morearty with:
the addition of a mysql_create function (configurable with a guid_generator accessor) for much better performance
id assignment is now done before_create instead of after_initialize, to more closely mimic the default Rails behavior of assigning an id upon save.

sudo gem install usesguid
In Rails environment file:
define ID as char(22) call “usesguid” in ActiveRecord class declaration, like:
class Mymodel < ActiveRecord::Base usesguid end
if your ID field is not called “ID”, call “usesguid :column =>'IdColumnName' ”
If you use MySQL as your database, you can make guid generation much faster by putting this in config/environment.rb:
ActiveRecord::Base.guid_generator = :mysql
