Module: RailsIdentity::UUIDModel

Included in:
Session, User
Defined in:
lib/rails_identity.rb

Overview

This module is a mixin that allows the model to use UUIDs instead of normal IDs. By including this module, the model class declares that the primary key is called “uuid” and an UUID is generated right before save(). You may assign an UUID prior to save, in which case, no new UUID will be generated.
