Migration error when used with condottieri_notification

[technolingo]

condottieri_notification app migration file 0001_initial dependencies reference nonexistent parent node ('pinax_notifications', '0002_auto_20180118_0138')

Any ideas?

raise NodeNotFoundError(self.error_message, self.key, origin=self.origin)
django.db.migrations.exceptions.NodeNotFoundError: Migration condottieri_notification.0001_initial dependencies reference nonexistent parent node ('pinax_notifications', '0002_auto_20180118_0138')

@evilplanet from your report it appears condottieri_notification is referencing an non-existent pinax-notifications migration. There have not been any migrations added to pinax-notifications since 2017-October-03, so something is wrong in that condottieri_notification migration.

The correct pinax-notifications migration reference is ('pinax_notifications', '0002_auto_20171003_2006').

Let us know how you make out.

I deleted all migrations files and re-generated them using makemigrations, this time I see ('pinax_notifications', '0003_auto_20180121_0216'). I can run migrate locally, no error. But when I push it to heroku and then try to migrate, the same issue occurs.

When I changed it into ('pinax_notifications', '0002_auto_20171003_2006') and run migrate on heroku, it still says django.db.migrations.exceptions.NodeNotFoundError.

It seems that I was using version 4.0.0, which does not have that migration, yet. I upgraded to 4.1.0, the issue disappears.

You shouldn’t delete migrations in pinax-notifications.

I just ran the following commands in the project repo:

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
find . -path "*/migrations/*.pyc"  -delete

I think I didn't delete pinax-notifications' migrations, since I installed it via pip (thus the migration files are not in the project repo). Or did I?
