django channels in the shell

[chris rose]

I'm trying to implement a custom management command into my app.

its purpose would be to check the database for a poll which fits time parameters and update clients via channels.

I want to get a list of the clients in a group, then decide whether or not to send them new information based on their session data

I have been exploring this in the shell and im wondering why my client doesn't receive a message when i use the following code:

from django.conf import settings

from django.utils.module_loading import import_string

config = getattr(settings, "CHANNEL_LAYERS", {})

backend_class = import_string(config['default']['BACKEND'])

channel_layer = backend_class(config['default'].get("CONFIG", {}))

channel = channel_layer.group_channels('poll')[0]

channel_layer.send(channel, {"text": "hello world!"})

solved it.. I had to explicitly add the hosts parameter

from django.conf import settings

from django.utils.module_loading import import_string

config = getattr(settings, "CHANNEL_LAYERS", {})

hosts = config['default']['CONFIG']['hosts']

backend_class = import_string(config['default']['BACKEND'])

channel_layer = backend_class(hosts=hosts)

I would recommend using the channel layer object directly instead in future:

from channels.asgi import get_channel_layer

channel_layer = get_channel_layer()

That will make sure all settings are applied the same.
