Missing migrations?

[rhblind]

When using a custom Device model ie. like the one below, makemigrations want to create migrations for the original model.

class FCMDevice(AbstractDevice):
    """
    Firebase Cloud messaging devices
    """
    user = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True, null=True)

    class Meta:
        verbose_name = _("FCM Device")
        verbose_name_plural = _("FCM Devices")

$ python manage.py makemigrations
Migrations for 'fcm':
  /Users/rolf/.virtualenvs/someproject/lib/python3.5/site-packages/fcm/migrations/0002_auto_20161213_1303.py:
    - Change Meta options on device

It seems like there's a missing migration.

I think it's generally not advisable to have meta options on the abstract base model, I've relocated model meta options to the child model in my fork and that solved the issue (no migrations were needed).

EDIT
Either that or inherit AbstractDevice's metaclass

class Device(AbstractDevice):
    class Meta(AbstractDevice.Meta):
        swappable = 'FCM_DEVICE_MODEL'
