 This is what the migration looks like:
 {{{

 class Migration(migrations.Migration):

     dependencies = [
         ('jobs', '0003_auto_20170222_1154'),
     ]

     operations = [
         migrations.AlterField(
             model_name='joblog',
             name='job',
 field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE,
 related_name='logs', to='jobs.Job'),
         ),
     ]

 }}}

 Running ./mange.py migrate makes no difference. I recently moved the
 codebase to Python 3.
 Below is the create table syntax for the relevant tables:
