title: Friendly_id for fixtures (slugs)
body: <p>I am using freindly_id in my application. I have setup a few fixtures in my application. I want to do integration testing on them. During the tests I need the friendly_id, but the DB records created from fixtures do not have the corresponding slugs in the Slug table. </p>
  
  <p>Aren't the slugs automatically created from Fixture data? If not then what can be a solution?</p>
