Lost migration

Hi. Thanks for great project!

I create City, Country, Region models in my own models file, exactly like in documentations. Next, I make a migrations, but except my own app migration, Django create migration for cities-light in third-party apps folder:

...
Migrations for 'cities_light':
  env/src/cities-light/cities_light/migrations/0008_auto_20170309_0153.py:
    - Alter unique_together for city (0 constraint(s))
    - Remove field country from city
    - Remove field region from city
    - Alter unique_together for region (0 constraint(s))
    - Remove field country from region
    - Delete model City
    - Delete model Country
    - Delete model Region

from django.db import migrations


class Migration(migrations.Migration):

    dependencies = [
        ('cities_light', '0007_make_country_name_not_unique'),
    ]

    operations = [
        migrations.AlterUniqueTogether(
            name='city',
            unique_together=set([]),
        ),
        migrations.RemoveField(
            model_name='city',
            name='country',
        ),
        migrations.RemoveField(
            model_name='city',
            name='region',
        ),
        migrations.AlterUniqueTogether(
            name='region',
            unique_together=set([]),
        ),
        migrations.RemoveField(
            model_name='region',
            name='country',
        ),
        migrations.DeleteModel(
            name='City',
        ),
        migrations.DeleteModel(
            name='Country',
        ),
        migrations.DeleteModel(
            name='Region',
        ),
    ]

My project deploy by CI, and just apply migrations only from project src. Third-party apps installs clearly every rebuild. So, I can’t put this migration into my project src.

Is it correct behavior? Or this is kind of my mistake?

I’ll update the docs

@Egregors I updated the comment, try this (as of 1.9 https://docs.djangoproject.com/en/1.10/ref/settings/#migration-modules):

MIGRATION_MODULES = {
    'cities_light': None
}
