title: Use Django Migrations to delete a table
body: <p>I am moving from Rails to Django and have an existing database. I created <code>models.py</code> via <code>python manage.py inspectdb &gt; models.py</code>, made changes, and tested some endpoints. Everything seems fine. </p>
  
  <p>I then ran <code>python manage.py makemigrations</code> and <code>migrate</code> to make the initial django mirgation. </p>
  
  <p>I noticed an old Rail's specific Model / table called <code>ArInternalMetadata</code> / <code>ar_internal_metadata</code>. I figure I could easily remove the table by simply removing the model from <code>models.py</code> and rerun <code>makemigrations</code> however when I do that, django just says <code>No changes detected</code>. Running <code>migrate</code> doesn't remove the table either.</p>
