Re: Multiplex results from (Django-Channels)

Thanks Andrew. I deleted the other post.

I'm do not quite follow. I don't have a "user" key anywhere. And do I need to do a for loop to get the results? An example would be great.

Cheers

Hi - I'll only reply to this thread, as you seem to have posted it twice with different subjects.

If you're going with the groups approach, as it seems you are, you need to add the user to multiple groups, one for each room, and then stick the room name in the group sends so you can distinguish them.

Hi,

I've currently setup Django channels to receive all the `messages` from a single `room`. However, I would like to set it up to receive `messages` from several rooms. In DRF, I'd use serializers to achieve this. However, in sockets, I am unsure how I would do it.

What is the correct

EG from chat rooms entitled `Foo` and `Bar` would look like this:

[
    {
        "label": "Foo",
        "pk": 5,
        "message": [
            {
                "handle": "Bruce",
                "message": "Yo"
            },
            {
                "handle": "Sol",
                "message": "Hey"
            }
        ]
    },
    {
        "label": "Bar",
        "pk": 10,
        "message": [
            {
                "handle": "Sol",
                "message": "Hi"
            },
            {
                "handle": "Alfred",
                "message": "Yo"
            }
        ]
    }
]

# consumers.py

@channel_session
def ws_connect(message):
    prefix, label = message['path'].strip('/').split('/')
    room = Room.objects.get(label=label)
    chathistory = room.messages.all().order_by('timestamp')
    Group('chat-' + label).add(message.reply_channel)
    message.channel_session['room'] = room.label
    message.reply_channel.send({'text': json.dumps([msg.as_dict() for msg in chathistory.all()])})

# models .py

class Room(models.Model):
    name = models.TextField()
    label = models.SlugField(unique=True)

class Message(models.Model):
    room = models.ForeignKey(Room, related_name='messages')
    handle = models.TextField()
    message = models.TextField()
    timestamp = models.DateTimeField(default=timezone.now, db_index=True)
    def __unicode__(self):
        return '[{timestamp}] {handle}: {message}'.format(**self.as_dict())


    @property
    def formatted_timestamp(self):
        return self.timestamp.strftime("%H:%M:%S")
   
    def as_dict(self):
        return {'pk':self.pk, 'handle': self.handle, 'message': self.message, 'timestamp': self.formatted_timestamp}
