Display date of birth in django app

Question

How to display age from dob obtained? Any suggestion?

models.py

from django.db import models
import datetime

dob = models.DateField(max_length=8)
age = models.IntegerField() 
def __str__(self):
    today = date.today()
        age = today.year - dob.year
    if today.month < dob.month or today.month == dob.month and today.day < dob.day:
        age -= 1
    return self.age 

Thank you, Rads

You should use the python-dateutil to get the relativedelta between dates:

from dateutil.relativedelta import relativedelta
from django.db import models

dob = models.DateField(max_length=8)
age = models.IntegerField() 
def __str__(self):
    today = date.today()
    delta = relativedelta(today, self.dob)
    return str(delta.years)
