Access any active record model in your application via a uid (uuid)

Why? I don’t want to expose any database ID’s to the outside world.

How?

  u = User.find(1)
  u.uid # = b0e43d5be1cf39db93aa5da6fc02b5b2
  u = User.find_by_uid('b0e43d5be1cf39db93aa5da6fc02b5b2')

Requirements

• uuid
• rails 2.3.2 (afaik)
