Is it possible to list channels stored in a Group?

Question

Is it possible to access the list of channels added in a Group with django-channels?

def consumer(message):
    Group("group_name").add(message.reply_channel)
    channel_list = Group("group_name").???

EDIT:

What I try to achieve is to have access to sessions of all channel, like the list of connected users for instance.

Thus far I use a database based system that lists the connections. But if the server shuts down without executing my ws_disconnect consumers, these connections object will remain in database, and I don't want this.

EDIT 2:

To list the connected users, I found django-channels-presence. I'll test it.

Answer 1

I've tested django-channels-presence and I easily succeeded to list the connected users for a Group by creating a Room (that handle Group management/creation, channel adding/removing...) and that provides a get_users() method that permits me to achieve what I was searching for.

It also provides a way to clean added channels that aren't deleted if the server crashes (that wouldn't trigger the ws_disconnect consumer that is used to delete these channels from the group). It provides the prune_presence and prune_room tasks that cleans expired channels.
