所以这是我的代码，第一个文件具有常规的日志记录设置，第二个部分具有celery任务记录器配置。每当我按下api-s时，每分钟都会根据代码生成一个新文件。但这不会发生。所有的celery任务日志信息都写入文件，该文件在celery启动后立即生成。但是我希望每次点击API时都将信息存储在一个新文件中，即每分钟应生成一个包含最近任务详细信息的新文件。

据我所知，Celery正在删除所有记录器并安装自己的记录器。如果要添加自定义记录器，则需要在setup_logging信号处理程序中进行操作，例如：

import celery.signals

@celery.signals.setup_logging.connect
def on_celery_setup_logging(**kwargs):
    # setup logging here
    pass

我从不需要这个，所以我不知道所有必要的细节。有关此问题的更多信息，请参见Celery文档的Logging部分。
