Django - How to calculate age of 10 years above

Question

I have a Model with the normal:

date_of_birth = models.DateTimeField(blank=True, null=True)

Please help me calculate those that are 10 years and above and display them in html. I need to set it so that as soon as someone turns 10 on todays date it automatically displays them.

Answer 1

Use relativedelta to subtract 10 years from your current time, then use it in your queryset:

from django.utils import timezone 
from dateutil.relativedelta import relativedelta

ten_years_ago_time = timezone.now() - relativedelta(years=10)
result = YourModel.objects.filter(date_of_birth__lt=ten_years_ago_time)

This code should goes to views.py , and nothing to do with models.py
