0.查看celery的worker状态 （worker==node）

(base) D:\djangotest\myrecrument>celery -A myrecrument  status
2021-01-23 00:12:53,091 job.views    68 INFO     i am in view
celery@DESKTOP-OTOBB8E: OK

1 node online.

1.检查已经注册的task

 D:\djangotest\myrecrument\mycelery> celery -A tasks inspect registered

2. D:\djangotest\myrecrument>  python manage.py check   检查django项目语法

3.celery delay 坑

def notify_interviewer(modeladmin,request,queryset):
    logger.info('i enter notify_interviewer...begin')
    candidates = ' '
    for obj in queryset:
        candidates = obj.username + ';' + candidates
    #dingtalk.send(candidates)
    
    send_dingtalk_message.delay(candidates)
    logger.info('i enter notify_interviewer...after delay')

项目目录 __init__.py 忘了添加以下内容，造成task.delay卡主

from __future__ import absolute_import, unicode_literals

# This will make sure the app is always imported when
# Django starts so that shared_task will use this app.
from .celery import app as celery_app  #少了这一点，delay就卡住发送不了消息

__all__ = ('celery_app',)
