I want to query the orders database every 5 minutes and alert admins that new orders have arrived.Would I use signals for this?
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.
Anyone have an example?
