How to call a function instead of an attribute in Django?

Question

Django

There is a model:

class Product(models.Model):
    price = models.FloatField('Цена')
    discount = models.IntegerField('Скидка')

When called in the object.price template, the price without the discount is displayed, which is correct. How can I display the discounted price?
Yes, I know you can write a method like get_price_with_discount and take the discount and price in it and display the result. Is there any way to do this with just the price? What would the discount be checked before its withdrawal?

# https://docs.python.org/3/library/decimal.html
from decimal import Decimal


class Product(models.Model):
    price = models.DecimalField('Цена')  
    # подумай, почему никто никогда не использует флоат для денег
    discount = models.IntegerField('Скидка')
    
    def get_price_with_discount(self):
         return self.price * Decimal(self.discount)
