I have 2 user types in my application (worker and company). Both user types are created with Devise. I'm currently trying to send a notification to a specific company with ActionCable.

My main problem is that when I send a notification every single company that's signed in receives it. I get that I'm supposed to include the company id in the stream name in some way, but I haven't had any luck so far.

I've included the working code that sends notifications to all companies below:

notifications_channel.rb

class NotificationsChannel < ApplicationCable::Channel

  def subscribed

    stream_from "notifications_channel"

  end



  def unsubscribed

    # Any cleanup needed when channel is unsubscribed

  end

end

connection.rb

module ApplicationCable

  class Connection < ActionCable::Connection::Base

  end

end

Call to the broadcast

ActionCable.server.broadcast 'notifications_channel', { 'My data' }

EDIT

I log the status of the notification with javascript:

notifications.js

App.notifications = App.cable.subscriptions.create("NotificationsChannel", {

  connected: function() {

    console.log("connected");

  };



  disconnected: function() {

    console.log("disconnected");

  };



  received: function(data) {

    console.log("recieved");

  };

});

Broadcast the message from your controller like this:

# Broadcast your message

ActionCable.server.broadcast "notifications_channel:#{target_user.id}

Now Update app/channels/application_cable/connection.rb with the below code

module ApplicationCable

  class Connection < ActionCable::Connection::Base

    identified_by :current_user



    def connect

      self.current_user = find_verified_user

      logger.add_tags 'ActionCable', current_user.name

    end



    protected



    def find_verified_user

      verified_user = User.find_by(id: cookies.signed['user.id'])

      if verified_user && cookies.signed['user.expires_at'] > Time.now

        verified_user

      else

        reject_unauthorized_connection

      end

    end

  end

end

And subscribe to the stream like this:

def subscribed

  stream_from "notifications_channel:#{current_user.id}"

end

Note: This is just an example to show how to target a specific user in Actioncable. You may have to modify the code based on
your requirement.

I also recommend watching this video by GoRails.

I managed to find the solution. Following Abhilashs answer took me most of the way, but I still had trouble authenticating the company. It seems like Warden was not fully configured, so this post made it work: env['warden'] not working with Rails 5
