title: Where to put helper functions when not using models and an ORM?
body: <p>I have to use PyMongo in a Django project, althought I have always used either Django's ORM or Mongoengine. With the old setup, every model had its own method which did some actual work. This time, having to use PyMongo, I don't have the models, and I don't know where to put the helper functions.  </p>
  
  <p>Currently I'm writing them inside the <code>models.py</code> file, but I'm not even halfway done that already I feel that this way I'm cluttering the models file (too many little functions).</p>
  
  <p>Do you know a better solution to the problem?</p>
