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)
With the date of birth calculation taken from here, you could put this function on your model. You wouldn't need to store age in the database.
from datetime import date
from django.db import models
class Person(models.Model):
dob = models.DateField()
def calculate_age(self):
today = date.today()
try:
birthday = self.dob.replace(year=today.year)
# raised when birth date is February 29 and the current year is not a leap year
except ValueError:
birthday = self.dob.replace(year=today.year, day=born.day-1)
if birthday > today:
return today.year - born.year - 1
else:
return today.year - born.year
