如何使用django使芹菜节拍任务对所有对象而不是单个对象有效？

我试图通过调度程序任务删除过期的收据，但我面临一个问题，因为每次函数运行时，它只删除一个对象，尽管还有很多对象。当调度程序每60分钟运行一次时，如何更改代码以确保它删除所有已过过期日期的对象

@periodic_task(run_every=crontab(minute='*/60'))
def delete_expired_receipts():
    receipts = Receipt.objects.all()
    for receipt in receipts:
        if receipt.expiry_date <= timezone.now():
            receipt.delete()
            return "deleted the receipts at {}".format(timezone.now())
    return "No receipts"

@定期任务（每运行一次=crontab（分钟='*/60'））
def delete_expired_receipts（）：
receives=Receipt.objects.all（）
收据中的收据：
如果receive.expiration\u date您需要删除循环中的return语句

@periodic_task(run_every=crontab(minute='*/60'))
def delete_expired_receipts():
    receipts = Receipt.objects.filter(expiry_date__lte=timezone.now())
    if receipts:
       receipts.delete()
       return "Reciepts have been deleted"
    return "No receipts"

您需要删除循环中的return语句

@periodic_task(run_every=crontab(minute='*/60'))
def delete_expired_receipts():
    receipts = Receipt.objects.filter(expiry_date__lte=timezone.now())
    if receipts:
       receipts.delete()
       return "Reciepts have been deleted"
    return "No receipts"
