Hi
I added a new app 'portfolio' in my project, but since then migrations
won't work anymore because Django seems to be trying to do them in the
wrong order.
*Running migrations:*
Applying core.0001_initial...* OK*
Applying contenttypes.0001_initial...* OK*
Applying contenttypes.0002_remove_content_type_name...* OK*
Applying auth.0001_initial...* OK*

, line 155, in get_app_config
return self.app_configs[app_label]
KeyError: 'portfolio'
During handling of the above exception, another exception occurred:
[...]
LookupError: No installed app with label 'portfolio'.
portfolio is listed in my INSTALLED_APPS :
LOCAL_APPS = (
'core',
'portfolio',
'user',
'data',
'editor',
)
INSTALLED_APPS = DJANGO_APPS + LOCAL_APPS + THIRD_PARTY_APPS
If I add a dependency in the problematic data.0002_auto_20200306_1522 migration
:
class Migration(migrations.Migration):
dependencies = [
('data', '0001_initial'),
('portfolio', '0001_initial'),
]
Other errors occur :
django.db.migrations.exceptions.NodeNotFoundError: Migration

('portfolio', '0001_initial')

ValueError: Dependency on app with no migrations: user
I get the same results with 'run_before'
The only way I have to make things work again is to comment out 'data' from
INSTALLED_APPS, make migrations, remove comments and migrate again :
Operations to perform:
Apply all migrations: admin, auth, contenttypes, core, portfolio, sessions
, user

Any help would be very much appreciated !
