Count number of records by date in Django

Question

I have a model similar to the following:

class Review(models.Model):
    venue = models.ForeignKey(Venue, db_index=True)
    review = models.TextField()  
           


        

Answer 1

If you were storing a date field, you could use this:

from django.db.models import Count

Review.objects.filter(venue__pk = 2)
    .values('date').annotate(event_count = Count('id'))

Because you're storing datetime, it's a little more complicated, but this should offer a good starting point. Check out the aggregation docs here.
