Django Celery时区配置错误或错误

Question

我将Django项目(从celery==2.5.5和django-celery==2.5.5)更新为celery==3.0.7和django-celery==3.0.6。然后奇怪的事情发生了。

我注意到的第一件事是Django Celery Admin界面中的每个日期/时间都偏移了3个小时。因为我的TIME_ZONE = 'Europe/Sofia'，现在是UTC/GMT +3小时，我认为问题与时区有关。

我查看了celerycam日志，发现了这个

UPDATE "djcelery_workerstate" SET "hostname" = 'three', "last_heartbeat" = '2012-09-18 17:57:49.000701+03:00' WHERE "djcelery_workerstate"."id" = 1 ; args=(u'three', u'2012-09-18 17:57:49.000701+03:00', 1)

last_heartbeat不正确，必须是2012-09-18 14:57:49.000701+03:00或2012-09-18 11:57:49.000701+00:00

也许某些函数期望日期时间不具有时区意识，但传递的日期时间实际上具有时区意识。

CeleryCam日志中的一个错误也证实了我的想法，这个错误只有在重试任务时才会发生！该任务具有此@task(default_retry_delay = 30, max_retries = 60)装饰器。

这就是错误：

Django/Celery更新后，我删除了所有数据库表，并使syncdb成为

Django项目的时区设置是：

TIME_ZONE = 'Europe/Sofia'
USE_TZ = True

Django/Celery设置为：

# RabbitMQ Broker
BROKER_HOST                = 'localhost'
BROKER_PORT                = 5672
BROKER_VHOST               = 'tixgate'
BROKER_USER                = 'tixgate'
BROKER_PASSWORD            = '*******'
# Redis Result Backend
CELERY_RESULT_BACKEND      = 'redis'
CELERY_REDIS_HOST          = 'localhost'
CELERY_REDIS_PORT          = 6379
CELERY_REDIS_DB            = 4
CELERY_REDIS_PASSWORD      = '*******'
CELERY_SEND_EVENTS         = True
CELERY_TASK_RESULT_EXPIRES = 60 * 60 * 24 # 1 day
CELERY_ALWAYS_EAGER        = False

并且我没有明确地设置CELERY_ENABLE_UTC或CELERY_TIMEZONE

编辑：celery==3.0.9和django-celery==3.0.9问题仍然存在

编辑：顺便说一下，celeryev显示了正确的日期时间(我想是GMT)

编辑：我使用PostgreSQL数据库

Answer 1

似乎这应该在新版本中得到修复，并建议将分支3.0作为临时解决方案https://github.com/celery/django-celery/issues/183#issuecomment-10846821.

Answer 2

如果你(像我一样)得到，也会出现这个问题

TIME_ZONE = 'UTC'
...
CELERY_TIMEZONE = 'Europe/Moscow'

在Djangosettings.py中。这两个字符串可以位于这个大型settings.py配置文件的不同部分，在这种情况下，Celery beat(例如)将向您显示时区已更改的消息。类似的事情：Timezone changed from 'UTC' to 'Europe/Moscow'，但你将看到的真实节拍仍将在UTC。要修复它，只需设置正确的DjangoTIME_ZONE设置：

TIME_ZONE = 'Europe/Moscow'

芹菜会捡起来的！

干杯。

Answer 3

至少根据发布说明，时区错误在0.8和0.9中得到了修复。

使用芹菜3.09和django芹菜3.0.9
