我正在尝试在项目中集成django_celery_beat。 当我使用django管理面板设置任务时，数据库中的条目被正确反映，当我开始项目任务成功执行时。但是，在第一次执行后，每次连续尝试发送任务都会失败，或者任何一条消息都没有发送给经纪人。
我的设置：
django_celery_beat : 1.0.1
celery: 4.0.1
在celeryconfig中设置：
CELERY_ENABLE_UTC = True
BROKER_URL = 'amqp://guest:guest@localhost:5672//'
CELERYBEAT_SCHEDULER = 'django_celery_beat.schedulers.DatabaseScheduler'

用于启动celerybeat的命令：
celery beat -A app-S django_celery_beat.schedulers.DatabaseScheduler --loglevel=INFO
命令：
celery worker -A app--loglevel=INFO
当我开始吃芹菜时，我确实例外：

然而，从上面发送的所有任务开始，芹菜只选择第一个任务，并在我开始服务器时执行。所有其他消息都被避免了。
任何人都可以帮助我。
