title: How to make autogenerated model attribute id to always be a string
body: <p>I have an application which uses a Mongo database. I often use the ID of the records which are ObjectIds/strings like <code>507f1f77bcf86cd799439011</code>.</p>
  
  <p>My issue is when I run my site i development mode, the Sails application is using in-memory store and uses numbers/interger as the objectId. That screws with my application.</p>
  
  <p>I want Sails to always store the id as an string.
  Whats the best way of dealing with this issue ?</p>
