我正在尝试使用 Django 1.10、Python 3.5 单独运行脚本，并且代码将使用 Django 模型。

该脚本位于 Django 项目的根目录中。

import os
import sys
import django
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proj.settings")
application = get_wsgi_application()


from pipeline.models import *
c = ModelName.objects.all()

我收到 django.core.exceptions.AppRegistryNotReady 的错误：尚未加载应用程序。对于以下代码行。应用程序 = get_wsgi_application()

之前我是使用django-extension-runscript来运行这些脚本来执行数据处理任务，但是它依赖于manage.py，它与celery不兼容（提供周期性任务管理。）

您有解决问题的想法或如何将 runscript 与 celery 结合使用吗？

这是完整的错误轨迹

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

我通过删除 proj/proj 目录中与 Celery 相关的所有文件（包括 celery.py、tasks.py 和init .py 中的内容）和 app_name/tasks 解决了这个问题。

但它们如何协同工作？
