Question

我正在尝试将celery 4.2版本集成到django项目中。根据文档，我已经在 init .py和celery.py中进行了更改，但是当我使用以下方法运行celery时：

python -m celery -A instaguide beat -l debug

我在下面得到了例外。我不确定缺少了什么。我在project.settings中定义的唯一CELERY_设置是CELERY_BROKER_URL，它不会抱怨没有连接到代理。因此，我在自己的设置或其他地方都缺少了其他东西。有任何线索吗？

我发现了问题所在。如果使用的是默认节拍计划程序，则需要使用至少一项计划任务来定义节拍计划程序配置。否则，如果使用数据库调度程序，则需要使用django-celery-beat来创建调度并将其存储在数据库中。因此，一个人至少需要有1个条目才能执行可重复的任务。另外@periodic_task批注已弃用，将在celery-5中删除，它似乎不起作用。

app.conf.beat_schedule = {
    # Executes every minute
    'add-every-monday-morning': {
        'task': 'users.tasks.test_task',
        'schedule': crontab(hour="*", minute="*"),
        'args': (),
    },
}
