How to redo a South migration after using –fake

If you are using Django South, you might accidentally use manage.py migrate [app] --fake at some point. To undo your mistake, use the following commands:

python manage.py shell
from south.models import MigrationHistory
m = MigrationHistory.objects.get(migration="<migration_name>")
m.delete()

That’s it! You can now safely perform your migration again.
