如何在Django中使用线程 [英] How to use thread in Django

问题描述

我想在一定时间内查看用户的订阅日期。并发送邮件给订阅正在完成的用户（例如提醒两天）。
我认为最好的方法是使用线程和计时器来检查日期。但是我不知道如何调用这个函数。我不想制作一个单独的程序或shell。我想结合这个程序到我的django代码。我试图在我的settings.py文件中调用这个函数。但似乎这不是一个好主意。它调用该函数并在每次导入设置时创建线程。

I want to check users' subscribed dates for certain period. And send mail to users whose subscription is finishing (ex. reminds two days). I think the best way is using thread and timer to check dates. But I have no idea how to call this function. I don't want to make a separate program or shell. I want to combine this procedure to my django code. I tried to call this function in my settings.py file. But it seems it is not a good idea. It calls the function and creates thread every time I imported settings.

推荐答案

使用 Django-cron 更容易和简单

编辑：从django_cron导入cronScheduler，添加一个提示

Added a tip

from django_cron import cronScheduler, Job
class sendMail(Job):
       # period run every 300 seconds (5 minutes)
        run_every = 300

        def job(self):
                # This will be executed every 5 minutes
                datatuple = check_subscription_finishing()
                send_mass_mail(datatuple)
//and just register it             
cronScheduler.register(sendMail)
