Django - 如何每天运行一个函数？

Question

我想每天午夜运行这个函数来检查expiry_date_notification。我能做什么？我是 Django 和 python 的新手。

def check_expiry_date(request):
    products = Product.objects.all()
    for product in products:
        product_id = product.id
        expiry_date = product.expiry_date
        notification_days = product.notification_days
        check_date = int((expiry_date - datetime.datetime.today()).days)
        if notification_days <= check_date:
            notification = Notification(product_id=product_id)
            notification.save()

Answer 1

正如其他人所说，Celery can schedule tasks to execute at a specific time .

from celery.schedules import crontab
from celery.task import periodic_task

@periodic_task(run_every=crontab(hour=7, minute=30, day_of_week="mon"))
def every_monday_morning():
    print("This is run every Monday morning at 7:30")

通过 pip install django-celery 安装
