* initial `models.py` in `test` app:

{{{
from django.db import models

class Thing(models.Model):

    things = models.ManyToManyField('self')
}}}

* do

{{{
manage.py makemigrations test
}}}

* change model's name:

{{{
from django.db import models

class OtherThing(models.Model):

    things = models.ManyToManyField('self')
}}}

* do

{{{
manage.py makemigrations test
manage.py migrate
}}}

* in `manage.py shell`:

{{{
from test.models import OtherThing; OtherThing.things.through.objects.all()
}}}
