Fixed #26339 -- Updated Question.was_published_recently() in tutorial 7 to...

    class Question(models.Model):

        # ...

        def was_published_recently(self):

            return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

            now = timezone.now()

            return now - datetime.timedelta(days=1) <= self.pub_date <= now

        was_published_recently.admin_order_field = 'pub_date'

        was_published_recently.boolean = True

        was_published_recently.short_description = 'Published recently?'
