On a fresh install of Django 2.1 or Django 2.2 a new migration is created on makemigrations.

[gabn88]

Actual behavior

A new migration is created on Django 2.1/2.2 when manage.py makemigrations is run:

# Generated by Django 2.2.7 on 2019-11-22 21:11

from django.db import migrations, models

class Migration(migrations.Migration):

    dependencies = [
        ('zinnia', '0004_on_delete_arg'),
    ]

    operations = [
        migrations.AlterField(
            model_name='category',
            name='level',
            field=models.PositiveIntegerField(editable=False),
        ),
        migrations.AlterField(
            model_name='category',
            name='lft',
            field=models.PositiveIntegerField(editable=False),
        ),
        migrations.AlterField(
            model_name='category',
            name='rght',
            field=models.PositiveIntegerField(editable=False),
        ),
    ]

Expected behavior

No new migration file is created.
