Erreur de mise à niveau Django 1.7: AppRegistryNotReady: les applications ne sont pas encore chargées.
J'essaie de mettre à niveau un projet de Django 1.6 à 1.7. Je reçois l'erreur suivante:

Django.wsgi:

Des idées sur ce qui pourrait être à l'origine de l'erreur et comment y remédier?

voir http://Django.readthedocs.org/fr/latest/releases/1.7.html#standalone-scripts
import Django
django.setup()
J'ai eu un problème similaire (le même?) Lors de la mise à niveau vers Django 1.7. Dans certains cas, il suffisait de mettre à jour le fichier wsgi: replace
import Django.core.handlers.wsgi
application = Django.core.handlers.wsgi.WSGIHandler()
avec
from Django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
Je regardais à travers tous ces fils pour que le céleri fonctionne sur les fenêtres (avec ce message d'erreur particulier) et je veux juste souligner le fait de mettre
import Django
django.setup()
au sommet de votre fichier tasks.py, c’est finalement ce qui me permet de le faire fonctionner.
INSTALLED_APPS Avait une virgule manquante dans le tableau, qui a causé l'erreur pour moi.
J'ai eu cette erreur lorsque j'ai essayé d'importer des modèles à partir de __init__.py de l'application, ce qui n'est pas possible.
Dans la configuration, le fichier d’application uwsgi (comme uwsgi.ini) remplace:
module = Django.core.handlers.wsgi:WSGIHandler()
sur
module=Django.core.wsgi:get_wsgi_application()
settings.AUTH_USER_MODEL est une chaîne (c’est pourquoi vous obtenez AttributeError: 'str' object has no attribute '_meta' - il attend un modèle) et ne doit être utilisé que dans les déclarations ForeignKey:
classe Article (modèles.Modèle): author = models.ForeignKey (settings.AUTH_USER_MODEL)
Si vous souhaitez faire référence à votre modèle d'utilisateur ailleurs, vous devez utiliser get_user_model:
depuis Django.contrib.auth import get_user_model UserModel = get_user_model ()
J'ai eu cette erreur en passant à un autre PC et en oubliant d'installer psycopg2 dans mon ordinateur et en utilisant 'ENGINE': 'Django.db.backends.postgresql', dans mes paramètres.
Peut-être que cela peut être utile à quelqu'un d'autre.
Dans mon cas, j'ai oublié d'ajouter l'une de mes sous-applications dans INSTALLED_APPS.
INSTALLED_APPS = [
'Django.contrib.admin',
'Django.contrib.auth',
'Django.contrib.contenttypes',
'Django.contrib.sessions',
'Django.contrib.messages',
'Django.contrib.staticfiles',
'basketball',
'basketball.area',
'basketball.game',
'basketball.player',
]
Dans mon cas, l'erreur a été provoquée lorsque j'ai mis à niveau le céleri à la version 4.x et que cela se trouvait dans INSTALLED_APPS: kombu.transport.Django. Supprimer cela a résolu le problème. Il semble que cela soit principalement dû à un chargement incorrect de Django lui-même.
Dans mon cas, SEcret_key a été commenté par erreur dans settings.py
