Django 定时任务

本文介绍怎么在一个django的项目里增加定时任务。

使用的框架为APScheduler， 安装APScheduler:

pip install apscheduler==2.1.2 

 安装完成后，打开django web 项目的urls.py 增加以下内容：

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()是需要被定时执行的任务，这里定义每60秒执行一次。

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

启动django 项目， 观察控制台，每60秒会有一个Hello Scheduler 输出：

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.
