在芹菜3.1中，做django定期任务 [英] In celery 3.1, making django periodic task

问题描述

在Django中，事情变化太大了，所以我不能使用3.1。我需要一些帮助。

我阅读了关于在django中进行任务，并阅读定期任务文档。但我不知道如何在django中定期执行任务。我认为这是因为我的低级英语..

在旧版本的Celery中，我导入了 djcelery & crontab ，并在 settings.py 中设置CELERYBEAT_SCHEDULE，并由 manage.py 排除。

但似乎我不能用这种方式执行芹菜de子了。比我应该把CELERYBEAT_SCHEDULE？在doc中的django示例中，他们在proj / proj / celery中设置 os.environ.setdefault（'DJANGO_SETTINGS_MODULE'，'proj.settings'）
的.py 。 （1）所以在 settings.py 中设置celerybeat（像以前一样）可以吗？

（2）如果可以的话，在django定期任务将非常有帮助。当我阅读教程时，最令人困惑的部分是文件路径。如果你不想提供一个完整的例子，我将非常感谢你解释我应该做什么工作，设置殴打和执行deamon。

感谢阅读。

解决方案

我假设你已经阅读了 django部分，但是你看到这个示例项目？

它不使用调度程序，但如果将其添加到设置.py ：

  from __future__ import absolute_import 
 
 from celery.schedules导入crontab 
 
 
 CELERYBEAT_SCHEDULE = {
＃crontab（hour = 0，minute = 0，day_of_week ='saturday'）
'schedule-name'：{＃示例：'file-backup'
'task'：'some_django_app.tasks ....'，＃example：'files.tasks.cleanup'
 'schedule'：crontab（...）
}，
} 
 
＃如果要将调度文件放在相对于您的项目或某项内容：
 CELERYBEAT_SCHEDULE_FILENAME =some / path / and / filename
  

现在对于命令，忘了 manage.py ，直接键入 celery

-B 可以一如既往地打败芹菜。

-A 的芹菜应用程序请注意示例项目的 celery.py 中的这一行： app = Celery（'proj'）

 芹菜-A proj工人-B -l info 
  

'django-celery'不需要 如果您需要从管理员管理
的计划，或者如果要通过django的ORM将任务结果存储在DB
中，则仅安装：

CELERYBEAT_SCHEDULER ='djcelery.schedulers.DatabaseScheduler'

Things changed too much in Django, so I can't use 3.1. I need some help.

I read about make a task in django, and read Periodic Tasks document. But I don't know how make periodic tasks in django. I think this becuase of my low level English..

In the older version of Celery, I imported djcelery&crontab and set CELERYBEAT_SCHEDULE in settings.py, and excuted by manage.py.

But it seems that I cannot execute celery deamon by that way anymore. Than where I should put CELERYBEAT_SCHEDULE? In django example in docs, they set os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'proj.settings') in proj/proj/celery.py. (1) So setting celerybeat in settings.py(like before) is ok?

(2) If you can, a tiny example of making periodic task in django will very helpful. When I was reading tutorials, the most confusing part was File Path. If you don't want to provide a whole example, I will really appreciate if you explain about where I should make tasks, set beat, and executed deamon.

Thanks for reading.

解决方案

I assume you've already read the django section from the docs, but have you seen this example project?

It doesn't use the scheduler but if you add this to settings.py:

from __future__ import absolute_import

from celery.schedules import crontab


CELERYBEAT_SCHEDULE = {
    # crontab(hour=0, minute=0, day_of_week='saturday')
    'schedule-name': {  # example: 'file-backup' 
        'task': 'some_django_app.tasks....',  # example: 'files.tasks.cleanup' 
        'schedule': crontab(...)
    },
}

# if you want to place the schedule file relative to your project or something:
CELERYBEAT_SCHEDULE_FILENAME = "some/path/and/filename"

Now for the commands, forget about manage.py, just type celery directly:

-B enables celery beat as always.

-A specifies the name of the celery app. Note this line in the celery.py of the example project: app = Celery('proj')

celery -A proj worker -B -l info

'django-celery' is not required, install it ONLY if you need to manage the schedule from the admin, or if you want to store task results in the DB through django's ORM:

INSTALLED_APPS += ('djcelery',)

# store schedule in the DB:
CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler'
