Assuming that you set_sub_date() function just sets the publish date
to when the item was created and easy way to do this is in the model
class PressRelease(models.Model):
pub_date = models.DateField(auto_now_add=True)
That will just set the pub_date to the current date when it is added
to the DB. Not sure if this was the functionality you were looking
for.
Cheers,
Dan
