This plugin for ActiveRecord makes the "ID" field into a URL-safe GUID It is a mashup by Andy Singleton [email protected] 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.

TO USE Install as a plugin in the rails directory vendor/plugin/guid 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
