UuidIt

You need to assign UUIDs to your Model? UuidIt makes it as simple as adding one line of code to the according models.

For actually generating the uuids this plugin uses spectra's ruby-uuid (http://github.com/spectra/ruby-uuid) whih is based on ruby-uuid (http://raa.ruby-lang.org/project/ruby-uuid/).

Installation

As a plugin

script/plugin install git://github.com/aduffeck/uuid_it.git
script/generate uuid_it
rake db:migrate

As a gem

Add the following line to your config/environment.rb file:

  config.gem "uuid_it"

script/generate uuid_it
rake db:migrate

Usage

class Car < ActiveRecord::Base
  uuid_it
end

@car.uuid # "9e5edacc-7163-11df-92bb-2d0a2c4dcb1c"

New UUIDs will be assigned when new objects are created. Already existing objects will get a UUID when it is read for the first time.
