Django 1.7アップグレードエラー：AppRegistryNotReady：アプリはまだロードされていません

プロジェクトをDjango 1.6から1.7にアップグレードしようとしています。次のエラーが表示されます。

エラーの原因と考えられる修正方法

更新1：

私は置き換えました：

from Django.contrib.auth.models import User

に：

from Django.conf import settings
User = settings.AUTH_USER_MODEL

そして、次のエラーが表示されます。

Django 1.7にアップグレードするときに、同様の（同じ？）問題がありました。場合によっては、wsgiファイルを更新するだけで十分でした：replace

import Django.core.handlers.wsgi
application = Django.core.handlers.wsgi.WSGIHandler()

と

from Django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

私はこれらのスレッドをすべて見て、セロリがウィンドウで動作するようにしました（この特定のエラーメッセージを使用）。

import Django
django.setup()

tasks.pyファイルの一番上に、これがついに機能しました。

HussienK

INSTALLED_APPS配列にコンマがないため、エラーが発生しました。

Mihkel L.

アプリの__init__.pyからモデルをインポートしようとしたときにこのエラーが発生しましたが、これは不可能です。

構成uwsgiアプリケーションファイル（uwsgi.iniなど）で以下を置き換えます。

module = Django.core.handlers.wsgi:WSGIHandler()

オン

module=Django.core.wsgi:get_wsgi_application()

Dmitriy Yusupov

settings.AUTH_USER_MODELは文字列です（そのため、AttributeError: 'str' object has no attribute '_meta'を取得します-モデルが必要です）、ForeignKey宣言でのみ使用する必要があります。

 class Article（models.Model）：
 author = models.ForeignKey（settings.AUTH_USER_MODEL）

ユーザーモデルを他の場所で参照する場合は、get_user_modelを使用する必要があります。

 Django.contrib.authからimport get_user_model 
 
 UserModel = get_user_model（）

別のPCに移動して、psycopg2をvenvにインストールするのを忘れ、設定で'ENGINE': 'Django.db.backends.postgresql',を使用すると、このエラーが発生しました。

おそらく、それは他の誰かに役立つ可能性があります。

私の場合、INSTALLED_APPS内にサブアプリケーションの1つを追加するのを忘れていました。

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',

私の場合、セロリを4.xにアップグレードしたときにエラーが発生し、INSTALLED_APPSにkombu.transport.Djangoが含まれていました。これを削除することで問題は解決しました。 Django自体の何らかの不正確なロードが原因であるようです。
