I know how to get avg, min and max value based on column via sql queries, i am wondering if using django ORM i can get all three average, max and minimum price using one query.

My django model look like this.

class Product(models.Model):
    name = models.CharField(max_length=300)
    price = models.DecimalField(max_digits=10, decimal_places=2)

Yes you can perform more than one aggeregate in django orm, aggregate() can handle more than one argument.

from django.db.models import Avg, Max, Min
Product.objects.aggregate(Avg('price'), Max('price'), Min('price'))


{'price__avg': 90.35, 'price__max': Decimal('290.20'), 'price__min': Decimal('12.99')}
