Compare and Difference between datetime.now() and datetimefield from db

I can't find any answer to this that works for me. I'm trying to check difference between datetime for created post with datetime.now()

example of what I would like to do in view.py

  if (datetime.now() - post.created_at).minutes > 10:
        Do_this
    else:
        Do_that

I have tried with timedelta things. Also tried strptime with datetime formats. No luck

When I print the datetime.now() i get: 2018-12-10 20:22:10.535052 And with the post.created_at: 2018-12-10 20:18:52:544396+00:00

How do I make them comparable?

Django is giving you a timezone-aware datetime object. datetime.now() is giving you a timezone-naive datetime object. You can't compare these.

Instead use django.utils.timezone.now(), which provides the type of datetime object that matches your Django settings (in your case, a timezone-aware datetime).

Also note that timedelta objects, as documented, don't have a minutes attribute. They do have a seconds attribute.

In summary:

if timezone.now() - post.created_at > timedelta(minutes=10):
    Do_this
else:
    Do_that
