我在基于Docker的设置中有Django Celery和Beat。我的环境被划分为他们关心的环境。CCD_ 1保持CCD_ 2和CCD_。在我的common.py中，我正在初始化一个变量，类似于
from datetime import datetime
import pytz
est_timezone = datetime.now(pytz.timezone('EST'))
这是我得到的追踪
celery-beat_1 | [2021-04-09 10:59:46,845: CRITICAL/MainProcess] beat raised exception <class 'TypeError'>: TypeError("'datetime.datetime' object is not callable")
你可以把上面的片段放在一个shell中，它运行得很好，所以我不知道发生了什么。
这是使用est_timezone变量的地方
CELERY_BEAT_SCHEDULE = {
'fetch_rates_on_weekdays': {
'task': 'where the task at',
'schedule': crontab(hour=CELERY_TIME_FOR_FETCH_RATES_ON_WEEKENDS, day_of_week='1-5',
nowfun=est_timezone)
}
}

如果您查看了Celery的文档，那么在传递日期时间对象时，nowfun期望有一个可调用的函数。芹菜文档
nowfun(可调用(–函数返回当前日期和时间作为类：~datetime.datetime.
因此，在这种情况下，您可以简单地将est_timezone更改为一个函数：
def est_timezone():
return datetime.now(pytz.timezone('EST'))
您的日程安排crontab将保持不变。
