GeneratesUUID

An ActiveRecord mixin to wrap the functionality of uuidtools UUID generation for a model’s attribute (database column). By default, this uuid is stored in a column named uuid, to override this behavior, pass a symbol with the column name.

Requirement

Requires the uuidtools gem found on rubyforge at: rubyforge.org/projects/uuidtools/

Example

Specify:

  class User < ActiveRecord::Base
    generates_uuid
  end

Create:

  u = User.create!
  u.uuid => "0ce453f2-9d25-11dc-8e13-001b63955101"

Use a different column name:

  class Resource < ActiveRecord::Base
    generates_uuid :token
  end

  r = Resource.create!
  r.token => "7b151730-9cb7-11dc-bb8c-001b63955101"
