In tutorial 07, a was_published_recently method definition should be modified to reflect previous modifications

[Damien Caselli]

In the ​Customize the admin change list section, the Question class order improvements show an old version of the was_published_recently method.

It gets improved in the ​Tutorial 5 section.

It shows:

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

When it should be:

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