Is it possible to use websocket in Rails without users?

Question

Ruby on Rails

Good time of the day. I am writing a trello clone using React + Rails.
There is a need to use web sockets for real time updates. Many of the websocket creation examples use users. That is, there is no registration and authorization, there are no users. There are only 3 models - Board, List, Card, as I understand it, use a web socket just for a permanent connection between the front and the server.

And actually the question is:
Can it be used in some way without authorization? . And if possible, how? What is the path for implementation?

(maybe a stupid question, sorry :))

Answer 1

Can. Use Broadcast.

class MessagesChannel < ApplicationCable::Channel  
  def subscribed
    stream_from "messages"
  end
end

Further in js is standard

(function() {
  this.App || (this.App = {});

  App.cable = ActionCable.createConsumer('/cable');

}).call(this);

Throw in the channel

ActionCable.server.broadcast('messages', message.to_json)

Reading

App.messages = App.cable.subscriptions.create('MessagesChannel', {  
  received: function(data) {
    var jsonObj = JSON.parse(data);
....
