  $ python manage.py dump2py 20200104
  $ ./pull.sh


As expected, there is some change in the database::

  $ python manage.py dump2py -o t
  Traceback (most recent call last):
  ...
  django.db.utils.OperationalError: (1054, "Unknown column 'comments_comment.private' in 'field list'")

I try using Django migrations::

  $ python manage.py makemigrations
  Started manage.py makemigrations (using lino_sites.jane.settings) --> PID 21156

  Done manage.py makemigrations (PID 21156)

So I do it the old way::

  $ mv migrations migrations.old
  $ python manage.py run 20200104/restore.py
