Passing data from consumer to channel layer used outside in another script

[yshalsager]

I am looking for a way to pass extra data from WS subscription to be used later using channel layer Using outside of consumers.

My use case is:

• The client sub is something like {'model': 'App.Model', 'a': 'b'}
• Consumer creates a group named 'App.Model' using await self.channel_layer.group_add(app_model, self.channel_name)
• Tasks script is running periodically and sends model updates to each group.

I need to pass a=b somehow from the consumer, so I can use it in the broadcasting job, apparently there's no way to do so, since storing the variable in scope isn't accessible outside the consumer. Also there's no way to check if a group name exists, so I can set group name to App.Model_b and check for it later.
