Send ActionCable to particular user
ruby-on-rails
Solution
You should use a channel that's specific to that user. For example:
"notifications_channel_#{current_user.id}"
This is also documented in an example from the actioncable repo here: https://github.com/rails/rails/tree/master/actioncable#channel-example-2-receiving-new-web-notifications
Problem
I have the following code which sends an ActionCable broadcast in my Rails application: `ActionCable.server.broadcast 'notification_channel', notification: 'Test message'` The connection looks as follows: ``` module ApplicationCable class Connection < ActionCable::Connection::Base identified_by :current_user def connect self.current_user = find_verified_user end def session cookies.encrypted[Rails.application.config.session_options[:key]] end protected def find_verified_user User.find_by(id: session['user_id']) end end end ``` However all users logged into the app will receive it. The `identified_by` only makes sure that logged in users can connect to the channel but it doesn't restrict which users get the broadcast. Is there a way to only sending a broadcast to a certain user? The only way I could think of doing it was: ``` ActionCable.server.broadcast 'notification_channel', notification: 'Test message' if current_user = User.find_by(id: 1) ``` Where the `1` is the ID of the user I want to target.
