【问题描述】：

我在 pythonanuwhere 上部署了我的 Django 应用程序，并希望将一个文件添加到计划任务中。但它给了我一个错误：

django.core.exceptions.ImproperlyConfigured：请求设置 LOGGING_CONFIG，但未配置设置。您必须在访问设置之前定义环境变量 DJANGO_SETTINGS_MODULE 或调用 settings.configure()。

我试过这个：

os.environ.setdefault('DJANGO_SETTING_MODULE', 'smsreminder.settings')
django.setup()

结果相同，但与 django.setup() 一致我要执行的文件中的脚本：

import datetime

from django_common.auth_backends import User

from reminder.models import Remind

from twilio.base.exceptions import TwilioRestException

from twilio.rest import Client

def my_scheduled_job():

    content = Remind.objects.all()
    account_sid = "--------------------------"
    auth_token = "--------------------------"
    for smscontent in content:
        if smscontent.remind_date == datetime.today().date():
            tempusers = User.objects.filter(username=smscontent.author)
            for recipient in tempusers:
                try:
                    client = Client(account_sid, auth_token)
                    message = client.messages.create(
                        body="I just want to remind, that you have some task for today {date}: {task}. {time} is the deadline!".format(
                            date=str(smscontent.remind_date), task=str(smscontent.title),
                            time=str(smscontent.remind_time)),
                        to=str(recipient.username),
                        from_="+18568889437")
                    print(message.sid)

                except TwilioRestException:
                    pass
    return

错误：

【问题讨论】：

虽然可以按照您尝试的方式在计划任务中运行 Django 代码，但您需要注意多个问题（例如确保路径是设置正确，导入顺序正确等），因此建议编写管理命令并将其作为计划任务运行。
这里是一个关于创建管理命令的 Django 文档的链接，如果有用的话：docs.djangoproject.com/en/3.2/howto/custom-management-commands

【解决方案1】：

我今天遇到了同样的问题：

按照错误提示

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.co
nfigure() before accessing settings.

设置S，不是设置。因此，您只需要使用大写的 S 更新您的初始代码

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'smsreminder.settings')
django.setup()
