Here's my Answer Model,
class Answer(models.Model):
likes = models.ManyToManyField(User, related_name='answer_likes')
timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
I wants to filter out the Answers which received Maximum likes in last 24 Hours. How can I do that in view?
Thank You :)
You need django aggregation api. Try:
from datetime import *
from django.db.models import Count
last_24 = datetime.now() - timedelta(hours = 24)
ans = Answer.objects.filter(timestamp__gte = last_24).annotate(counted_likes = Count('likes')).order_by('-counted_likes')
Now you can ans[0].counted_likesto find out how many likes answer ans[0] have, and order_by term up there assures to you that this first element has the largest number of likes.
See aggregation in django docs for further explanations.
