Re: Save the user from one model to the another model

You're probably looking for something along the lines of:

thread = Thread.objects.get(id=<someid>)
msg = Message.objects.get(id=<someid>)

thread.user.add(msg.sender)

Look at add() and remove() methods in documentation (search for related managers).

FYI - it's a good practice to name fields that use ManyToMany field in plural, i.e. Thread.users would be better than Thread.user

Subject: Save the user from one model to the another model

What I want to do is, whenever I create a new message, I want the sender of the Message to be added to the user of the Thread. How do I do that?

 

class Thread(models.Model):
    user = models.ManyToManyField(User)
    is_hidden = models.ManyToManyField(User, related_name='hidden_thread', blank=True)

    def __unicode__(self):
        return unicode(self.id)

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" % (unicode(self.thread.id), self.body)
