Thank you all so much for the answers! I came up with this solution.
class Message(models.Model):
thread = models.ForeignKey(Thread)
sent_date = models.DateTimeField(default=datetime.now)
sender = models.ForeignKey(User)
body = models.TextField()
is_hidden = models.ManyToManyField(User, related_name='hidden_message',
blank=True)
def __unicode__(self):
return "%s - %s - %s" % (unicode(self.thread.id), self.body,
self.sender)
def save(self, *args, **kwargs):
probably_new = (self.pk is None)
super(Message, self).save(*args, **kwargs)
if probably_new:
self.thread.user.add(self.sender)
Please correct me, if this is not a good option. But with signals I can
check whether its a new created message or not. Does this have any draw
backs? Thank you once again!
