title: Get ID of Rails Model before saving...?
body: <p>How do you get the id of a rails model before it is saved?</p>
  
  <p>For example, if I create a new model instance, how can I get its ID before it is saved?  </p>
  
  <p>I know that the id is created onsave and according to the database but is there a workaround?</p>
