I want to check for new orders in the background?

[frocco]

Hello,

I want to query the orders database every 5 minutes and alert admins that new orders have arrived.

Would I use signals for this?

Anyone have an example?

Thank you

Would I send a signal after an order is saved?

This is not working, the to: never gets called.

from:

user_order = Signal(providing_args=["request", "order"])
user_order.send(sender=None, request=request, order=order)

to:

def user_order_handler(sender, **kwargs):

        order = kwargs('order')

user_order.connect(user_order_handler)

Using a receiver attached to the post_save signal of your Order model would certainly be more efficient than polling the database. You could also generate the e-mail inside the save() method of your model. However you need to be careful as both may block your application.

Everything you need is here: https://docs.djangoproject.com/en/dev/topics/signals/

Take a look at django-notifications app - https://github.com/pinax/django-notification

you can check the example of it on this SO thread - http://stackoverflow.com/questions/1609775/how-do-i-display-notifications-from-django-notification
