Can this be done with the ORM? - Django
- by RadiantHex
Hi folks,
I have a few item listed in a database, ordered through Reddit's algorithm.
This is it:
def reddit_ranking(post):
t = time.mktime(post.created_on.timetuple()) - 1134000000
x = post.score
if x>0: y=1
elif x==0: y=-0
else: y=-1
if x<0: z=1
else: z=x
return (log(z) + y * t/45000)
I'm wondering if there is any clever way of using Django's ORM, in order to UPDATE the models in bulk.
Without doing this:
items = Item.objects.filter(created_on__gte=datetime.now()-timedelta(days=7))
for item in items:
item.reddit_rank = reddit_rank(item)
item.save()
I know about the F() object, but I can't figure out if this function can be performed inside the ORM.
Any ideas?
Help would be very much appreciated!
