我刚开始使用Django芹菜并加入我的项目
但是我无法在控制台中看到print语句或return语句
我看着这里：Print statement in Celery scheduled task doesn't appear in terminal
simple celery test with Print doesn't go to Terminal
系统：Windows，Pycharm，Python3，django 1.9，Celery 4.02，django-celery-beat 1.01
驱动/ celery.py
from __future__ import absolute_import, unicode_literals
from celery import Celery
from celery.schedules import crontab
import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'advocate.local_settings')
app = Celery(
'drive',
broker='redis://localhost:6379/0',
include=['drive.celery_tasks']
)
app.config_from_object('django.conf:settings', namespace='CELERY')
app.conf.beat_schedule = {
'add-every-minute': {
'task': 'drive.celery_tasks.add',
'schedule': crontab(),
},
}
app.conf.timezone = 'UTC'
# Optional configuration, see the application user guide.
app.conf.update(
result_expires=3600,
)
if __name__ == '__main__':
app.start()
驱动/ celery_tasks.py
from __future__ import absolute_import, unicode_literals
from drive.celery import app
from datetime import datetime
@app.task
def add():
temp = str(datetime.now())
print(temp)
return 2 + 3
芹菜跑命令
celery -A drive beat -l info
在控制台中显示
