What is the correct way to display DateTimefield in Django?

Question

Django

In the settings is:

TIME_ZONE = 'Europe/Samara'
USE_TZ = True

In the model:

class A(models.Model):
    created = models.DateTimeField()

    def __str__(self):
        return 'Заявка от {}'.format(self.created.strftime('%d.%m.%Y %H:%M'))

It is displayed :
Заявка от 15.05.2018 09:30
And I need it to be output like this:
Заявка от 15.05.2018 13:30
If I write like this:

def __str__(self):
    return self.created

Then it is displayed:
15 мая 2018 13:30
Question:
How to write the code correctly so that everything is displayed as I need with the correct TZ?

Answer 1

Django stores such objects in UTC, and applies the time zone at the time of rendering to the template. Those. you have to do it by hand.

from django.utils import timezone
tz = timezone.get_default_timezone()

class A(models.Model):
    created = models.DateTimeField()
    def __str__(self):
        return 'Заявка от {}'.format(self.created.astimezone(tz).strftime('%d.%m.%Y %H:%M'))
