Do you really need a CharField here or would a simply string variable be
enough? So you could simply do something like
class Message(models.Model):
description = models.CharField(maxlength=200)
author = models.ForeignKey(User)
temp = ""
and it should never get stored in the database as far as I know... Or do
you need to have a CharField for a specific reason?
