title: Where to put routines in Django project?
body: <p>I have rather vast implementation of functionality needed for processing specific type of data stored in my Django DB (7 interconnected files containing ~100 lines of code each). There's a facade method in one of those files that I call from related method in <code>views.py</code> so that there is no mess inside of views file.  </p>
  
  <p>For now I put everything inside a new folder in the same directory where <code>settings.py</code> <code>urls.py</code> and <code>wsgi.py</code> are, but now every time I'm calling <code>makemigrations</code> I receive a handful of unrelated information that has nothing to do with changes in data model.</p>
  
  <p>What is the best place to store those routines? </p>
