Django每天在特定时间运行定期任务

Question

我想在每天下午6:30运行django-芹菜定期任务

tasks.py

import celery
from datetime import datetime
@celery.task
def my_task():
print(' task called ')
print(datetime.now())
return True

celery.py

from __future__ import absolute_import, unicode_literals
from celery import Celery
from tasks import my_task
from celery.schedules import crontab
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'my_app.settings')
celery_instance = Celery('my_app')
celery_instance.config_from_object('django.conf:settings', namespace='CELERY')
celery_instance.autodiscover_tasks()
@celery_instance.on_after_configure.connect
def setup_periodic_tasks(sender, **kwargs):
sender.add_periodic_task(
crontab(minute=30, hour=18, day_of_week='mon,tue,wed,thu,fri,sat,sun'),
my_task.s(),
)
# when i try this it work of every 1 min
sender.add_periodic_task(
crontab(minute='*/1'),
my_task.s(),
)

当我打芹菜的时候-A app_name worker-B

任务在下午6:30没有命中

Answer 1

只需删除day_of_week参数。

只保留crontab(hour=18, minute=30)#它将在您设定的时区每天下午6:30运行。
