Python/Django: sending emails in the background

问题

Imagine a situation in which a user performs an action on a website and admins are notified. Imagine there are 20 admins to notify. By using normal methods for sending emails with Django the user will have to wait until all the emails are sent before being able to proceed.

How can I send all the emails in a separate process so the user doesn't have to wait? Is it possible?

回答1:

Use celery as a task queue and django-celery-email which is an Django e-mail backend that dispatches e-mail sending to a celery task.

回答2:

Another option is django-mailer. It queues up mail in a database table and then you use a cron job to send them.

A thread may be a possible solution. I use threads intensively in my application for haevy tasks.

# This Python file uses the following encoding: utf-8

#threading
from threading import Thread

...

class afegeixThread(Thread):

    def __init__ (self,usuari, parameter=None):
        Thread.__init__(self)
        self.parameter = parameter
        ...

    def run(self):        
        errors = []
        try:
             if self.paramenter:
                   ....
        except Exception, e:                
             ...
...

n = afegeixThread( 'p1' )
n.start()
