Django 定時任務

本文介紹怎么在一個django的項目里增加定時任務。

使用的框架為APScheduler， 安裝APScheduler:

pip install apscheduler==2.1.2 

 安裝完成后，打開django web 項目的urls.py 增加以下內容：

from apscheduler.scheduler import  Scheduler
from siteathome import tests

sched = Scheduler()

@sched.interval_schedule(seconds=60)
def my_task():
    tests.testFuncton()

sched.start()

其中， siteathome.tests 里面的testFunction()是需要被定時執行的任務，這里定義每60秒執行一次。

def testFuncton():
    print("Hello Scheduler")

啟動django 項目， 觀察控制台，每60秒會有一個Hello Scheduler 輸出：

Performing system checks...

You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.
