Could anybody help me out as I am new to Django.
*In my model:*
from django.db import models
class Employees(models.Model):
empId = models.AutoField(primary_key=True)
empName = models.CharField(max_length=200)
empEmail = models.EmailField()
empMob = models.CharField(max_length=200
Thank you Erik. I will try the property method.

#Z value calculation
#
#step1: converting lat and long to int
latitude int = (latitude + 90) × 10^6
longitude int = (latitude + 180) × 10^6
#note 10^6 = 100
We compute the Morton value for a spatial point P (x, y)
by interleaving the bits of x and y. For exam
