title: mongoose where to put model functions that can be exposed globally
body: <p>I am using <code>utils.js</code> right now which can be required anywhere in my API controllers.</p>
  
  <p>I'm wondering if this is a good way of doing it.</p>
  
  <p>I might call methods whenever I have a Job object like:</p>
  
  <pre><code>var require('../utils');
  
  //express route callback
  job = utils.job.getCreatorProfile(job);
  res.send(job);
  </code></pre>
