Django-Projekt Neustrukturierung: Kann App nicht importieren

Question

Ich versuche, mein Projekt zu restrukturieren, um die Empfehlung in den neuesten zwei Scoops von Django Buch (für Django 1.11) zu entsprechen.

Nach Abschluss der Umstrukturierung kann meine App nicht importiert werden.

Beim Laufen

python3 manage.py runserver --settings=config.settings.settings 

ich:

ImportError: No module named 'dash' 

secureDash.dash.apps.DashConfig:

from django.apps import AppConfig 


class DashConfig(AppConfig): 
    name = 'dash' 

Answer 1

Ersetzen secureDash.dash.apps.DashConfig mit secureDash.dash in INSTALLED_APPS sollte es beheben.
