UUIDPrimaryKey

==============

Copyright 2006-2007, Chris Hapgood

Derived from the works of several others, including Demetrio Nunes, Paul Dix and Lee Jensen.

Requirements: UUIDTools GEM (gem install uuidtools)

In any model class requiring a UUID PK, invoke UUIDPrimaryKey, optionally with 

the name of the PK column in your database.  Example: 

  class Person < ActiveRecord::Base

  	UUIDPrimaryKey

  end

  

  class Place < ActiveRecord::Base

    UUIDPrimaryKey :column => 'uuid'

  end

 

Hints:

  1. To override the value of the PK from the application, define an 

  initialize method in your model like this:

   class Person < ActiveRecord::Base

     UUIDPrimaryKey :column => 'uuid'

    

     def initialize(params = nil)

       super

       self.id = params[:uuid] unless params[:uuid].nil?

     end

   end

  

  2. To define a reasonable colum using migrations, try this:

   class AddPeople < ActiveRecord::Migration

     def self.up

       create_table :people, :id => false do |t|

         t.column :uuid, :string, :limit => 36

         t.column :firstnames, :string, :limit => 55

         t.column :lastname, :string, :limit => 35

         t.column :created_at, :timestamp

         t.column :updated_at, :timestamp

       end

         execute("ALTER TABLE people ADD PRIMARY KEY(uuid)")

     end

   

     def self.down

       drop_table :people

     end

   end
