I have now succesfully setup Django-celery to check after my existing tasks to remind the user by email when the task is due:

@periodic_task(run_every=datetime.timedelta(minutes=1))  
def check_for_tasks():      
    tasks = mdls.Task.objects.all()
    now = datetime.datetime.utcnow().replace(tzinfo=utc,second=00, microsecond=00)
    for task in tasks:
        if task.reminder_date_time == now:
            sendmail(...)

So far so good, however what if I wanted to also display a popup to the user as a reminder?

Twitter bootstrap allows creating popups and displaying them from javascript:

$(this).modal('show');

The problem is though, how can a celery worker daemon run this javascript on the user's browser? Maybe I am going a complete wrong way and this is not possible at all. Therefore the question remains can a cronjob on celery ever be used to achieve a ui notification on the browser?
