Comment (by Simon Charette):
Sergey,
> Unmanaged models should not work in migrations by their nature.
Is there a reason for that? How would the migration framework know how to
generate references from managed models to unmanaged ones then (e.g. a
foreign key)? The migration framework has supported managed model
references for a while and even
[https://docs.djangoproject.com/en/2.1/howto/writing-migrations/#changing-
an-unmanaged-model-to-managed documents how to move an unmanaged model to
a managed one].
> You can make direct import of this model in migrations and use it.
Direct model imports in migrations will break over time if the model
definition happen to change and won't work when mixed up with
state/migration models. The
[https://docs.djangoproject.com/en/2.1/topics/migrations/#historical-
models documentation warns about this pattern].
I still believe this is a legitimate bug.
