How to stack object property values ​​in db using django?

Question

Django

There is a database model:

class Order(models.Model):
    data = models.DateField()
    time = models.TimeField(null=True)
    status = models.BooleanField(default=False)    
    order_type = models.CharField(max_length=20)
    name = models.CharField(max_length=60, null=True)
    count = models.IntegerField(null=True)
    comment = models.CharField(max_length=60, null=True)

The count property defines a number - a certain amount. How to add the values ​​of the count property of multiple objects and return the sum?
