title: cant use .native function in sails mongo
body: <p>I've been working around some ways to use .native() to do a simple aggregation function in sails with mongo.</p>
  
  <p>Already following the steps to install dependencies. (<a href="http://sailsjs.org/documentation/reference/waterline-orm/models/native" rel="nofollow">http://sailsjs.org/documentation/reference/waterline-orm/models/native</a>)</p>
  
  <p>But still it returns me this error : <a href="http://i.stack.imgur.com/7aDS5.png" rel="nofollow">.native is not a function</a></p>
  
  <p>Did I missed something ?</p>
