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*

Applying auth.0002_alter_permission_name_max_length...* OK*

Applying auth.0003_alter_user_email_max_length...* OK*

Applying auth.0005_alter_user_last_login_null...* OK*

Applying auth.0006_require_contenttypes_0002...* OK*

Applying auth.0007_alter_validators_add_error_messages...* OK*

Applying auth.0008_alter_user_username_max_length...* OK*

Applying auth.0009_alter_user_last_name_max_length...* OK*

Applying admin.0001_initial...* OK*

Applying admin.0002_logentry_remove_auto_add...* OK*

Applying admin.0003_logentry_add_action_flag_choices...* OK*

Applying data.0001_initial...* OK*

Applying data.0002_auto_20200306_1522...Traceback (most recent call last):

File 
"/opt/miniconda3/envs/cert_tool/lib/python3.7/site-packages/django/apps/registry.py"
, 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 
data.0002_auto_20200306_1522 dependencies reference nonexistent parent node 
('portfolio', '0001_initial')

Traceback (most recent call last):

"/opt/miniconda3/envs/cert_tool/lib/python3.7/site-packages/django/db/migrations/loader.py",
 
line 166, in check_key

    return self.graph.root_nodes(key[0])[0]

IndexError: list index out of range

    raise ValueError("Dependency on app with no migrations: %s" % key[0])

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 !
