Description (last modified by Mariusz Felisiak)

The following function produces an error in the Tutorial 2. It can be problematic for new users that are getting acquainted with Django and do not know how to fix this issue.

class Question(models.Model):
    # ...
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

returns the following error:

TypeError: can't compare datetime.datetime to datetime.date

It is easily fixed invoking the date method from now in the following way.

class Question(models.Model):
    # ...
    def was_published_recently(self):
        return self.pub_date >= timezone.now().date() - datetime.timedelta(days=1)

You've probably made a mistake somewhere, because pub_date is a DateTimeField so tutorial works properly. Closing per TicketClosingReasons/UseSupportChannels.
