Re: Corrupted Migration?

Thanks for the reply. I should have mentioned that I tried all of that: the problem is the model state is ahead of the database state, not behind it. It seems that the database migration was atomic, so everything was rolled back as that transaction failed, but the same thing didn't happen at the model level. So, now I'm stuck with a model state that the previous migrations don't capture.

Do it again. Delete the migration. Take note of the last valid
migration. Open the django_migrations table and delete the migration
record(s) after the last valid migration.

makemigrations again and then migrate again to bring the database into
line with your models.

BTW, the shell is looking at the model not the database.
