Django channels

Hi,

I'm creating a prototype using Django Channels and I have a question that I haven't sorted out yet. First of all, big thanks to all django-channels developer, this is something I was missing for a long time.

So I have a connection that watches on a model and sends updates to a frontend. It looks something like this:

from channels import route_class
from channels.generic.websockets import WebsocketDemultiplexer

from dataSource.models import DataSourceBinding

class Demultiplexer(WebsocketDemultiplexer):
  consumers = {
    "datasource": DataSourceBinding.consumer,
  }


  def connection_groups(self):
    return ["datasource-updates"]

channel_routing = [
  route_class(Demultiplexer, path="^/datasource/")
]

It works fine as far as some change is done, but I'd like to get initial data for an initial render, is there any good trick how to do this? I do I need to send a message and do it manually somehow? 

Thank you.
