Steps to reproduce:
* add `test` app with `models.py`:
{{{
class Thing(models.Model):
pass
class SuperThing(Thing):
pass
}}}
* do
{{{
manage.py makemigrations test
}}}
* change `models.py`:
{{{
class SuperThing(models.Model):
thing_ptr = models.AutoField(primary_key=True)
}}}
* do
{{{
manage.py makemigrations test
}}}
* do it one more time
{{{
manage.py makemigrations test
}}}
last command results in
{{{
django.db.migrations.state.InvalidBasesError: Cannot resolve bases for
[<ModelState: 'test.SuperThing'>]
This can happen if you are inheriting models from an app with migrations
(e.g. contrib.auth)
in an app with no migrations; see
https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies for
more
