django.core.exceptions.AppRegistryNotReady:应用尚未加载.(django 2.0.1)(Python 3.6) [英] django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet. (django 2.0.1)(Python 3.6)
问题描述
这是我第一次尝试将Django应用程序(django 2.0.1)(Python 3.6)部署到pythonanywhere，这是一个没有模型，没有引导程序的简单组合应用程序.只是Django，HTML，CSS&Javascript.
It's my first time trying to deploy a Django app(django 2.0.1)(Python 3.6) to pythonanywhere, it is a simple portfolio app with no models, no bootstrap. Just Django, HTML, CSS & Javascript.
使用其bash控制台将其从Github存储库中拉到pythnanywhere后，我运行:
After pulling it from the Github repo onto pythnanywhere with their bash console, I run :
python manage.py migrate
&遇到此错误:
& was hit with this error :

我厌倦了在所有可能找到的解决方案中寻找解决方案，但是并没有什么真正的帮助，我什至尝试将这一行添加到我的settings.py中:
I tired looking for solutions everywhere I could possibly find but nothing really helps, I've even tried adding this line to my settings.py :
import django
django.setup()
在此行下面:
SECRET_KEY = os.environ.get("SECRET_KEY")
根据此帖子的建议，但无济于事.
as suggested from this post, but to no avail.
这是我的设置.py:

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATE_DIR = os.path.join(BASE_DIR, "templates")
STATIC_DIR = os.path.join(BASE_DIR, "static")

我真的迷失了这一点，希望有人可以帮助您弄清这里真正的问题是什么.
I am really lost on this, hoping someone can help shed some light on what's the real problem here.
推荐答案
刚刚克服了类似情况.
您真正需要的就是这个:
All you really need is this:
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "your_project.settings")
然后是这些行:
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
此后，您可以轻松导入模型而无需 AppRegistryNotReady:应用尚未加载.
After that you can easily import models without AppRegistryNotReady: Apps aren't loaded yet.
更新:这实际上就是项目文件夹中wsgi.py文件中的4行代码.
UPDATE: This is really exactly the 4 code lines from wsgi.py file in your project's folder.
用于DJANGO 3.0 在Django 3+中，需要一个额外的变量来解决同步/异步混乱:
FOR DJANGO 3.0 In Django 3+ an extra variable is needed to resolve sync/async confusing:
os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"
