change the code order_date_time=models.DateField(datetime.datetime.now()) to order_date_time=models.DateField(timezone.now) default=datetime.datetime.now() is evaluated at parsing/compile time of the model. It is not changed afterwards. To evaluate now() at the time of adding/updating an object, you have to use: default=timezone.now, which sets now as the callable.
