Celery注册任务，但Beat无法从已安装的应用程序调度任务

Question

我在让Celery / Celery Beat安排我的celery.py文件中的任务以外的其他任务时遇到了问题。我可以看到任务已在“芹菜检查已注册”中注册，但是任务未按计划运行。我已经阅读了所有文档，并且碰壁了。在Windows上使用Ubuntu WSL运行Redis。

测试-每10秒运行良好，并显示在我的shell中PayClosedLines-已注册，但在运行芹菜工人时不会出现在外壳中。

板球 ...这就是问题所在。我安装了django-celery-beat，所以我需要像这样启动我的beat worker。菜鸟太多了，不知道为什么，但这有效。

celery -A mysite beat -l info --scheduler django_celery_beat.schedulers:DatabaseScheduler

而不是通常的

celery -A mysite beat
