hello all, together with my Djano app, I am using an independently- running python scripts, using Django's ORMs. It's running like a daemon, check one table in DB, and calls function at pre-set time. The main codes are like:
def main_daemon(): for event in Daemon_Event.objects.filter(event_occur_time__lte=datetime.datetime.now() +datetime.timedelta(seconds=60)): #get all daemon event which will occur within 1 min. s = (event.event_occur_time-datetime.datetime.now()).seconds from django.db import connection connection.close() sleep(s) event_handler(event) def event_handler(event): ###something to deal with the event print event.related_model_set.get() #for test And because the Web users can delete events he started, if I don't use from django.db import connection connection.close() when one event is in the sleep(s) time, and user deletes that event, then the event_handler(event) will result something strange ( but no programme error...). for example, after user delete one event, I can't see the record in database table, but in event_handler(event), the "print" will still print out the related model object. so, I added the connection.close(), then the "print" assert exception as objects doesn't exist, as I expected. What I want to know is that: before sleep(s), I closed the connect, and does is re-open database connection automaticly in event_handler()? is it safe to use like this? btw, the main_daemon is under transaction.manually_commit(). thanks a lot in advance. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
