Rails 7.1: ActionCable not broadcasting messages to specific rooms based on user roles
I'm integrating two systems and I'm having trouble with ActionCable in Rails 7.1. I set up a chat application where users can send and receive messages in different rooms. However, I'm working with an scenario where messages aren't being broadcast to the correct rooms based on user roles. For instance, users with a 'moderator' role should receive messages from all rooms, while 'regular' users should only receive messages from their assigned room. I have a `ChatChannel` that looks like this: ```ruby class ChatChannel < ApplicationCable::Channel def subscribed if current_user.role == 'moderator' stream_from 'chat_room:*' else stream_from "chat_room:#{current_user.room_id}" end end def receive(data) ActionCable.server.broadcast("chat_room:#{data['room_id']}", data) end end ``` In my `create` action of the `MessagesController`, I’m trying to broadcast the message like this: ```ruby class MessagesController < ApplicationController def create @message = Message.new(message_params) if @message.save ActionCable.server.broadcast("chat_room:#{@message.room_id}", message: @message.content, user: current_user.username) head :ok else render json: { errors: @message.errors.full_messages }, status: :unprocessable_entity end end private def message_params params.require(:message).permit(:content, :room_id) end end ``` I expected that when a message is created in a particular room, it would be broadcasted to users subscribed to that room. However, it seems that moderators receive messages from their rooms, but regular users do not receive messages at all, regardless of their role. I’ve checked the logs, and I see the messages being saved but not the broadcast action being triggered for regular users. I tried adding debug statements in the `subscribed` method to confirm that the users are subscribing correctly, and they are. However, the broadcast doesn’t seem to work as intended. I also verified that the `room_id` being passed is correct. I am running Rails 7.1 with ActionCable configured in `config/cable.yml` for both development and production environments. Any guidance on how to ensure that messages are correctly broadcast to users based on their roles would be highly appreciated! I'm working on a REST API that needs to handle this. Any advice would be much appreciated.
