ActiveGuid

Add a GUID column to Active Record instances. Useful for providing an unambiguous ID that doesn't also reveal anything about your database.

There is no way to customize the column name at this time - it has to be guid, a string of 32 characters.

Requires UUIDTools ~> 2.1, Rails ~> 3 and Ruby 1.9.2.

Usage

create_table 'users' do |t|
  t.string 'guid', limit: 32
end

class User < ActiveRecord::Base
  include ActiveGuid
end

u = User.new
u.valid? # GUID is generated before_validation

u.guid # => 'e5a49bdd-72a0-4e72-802a-637c22ab6507' or whatever
