Rails - WebSocket

I want to push data to client using WebSocket. I dont now how to return data(from Redis) to client. Could somebody explain me that?

sockets_controller.rb

class SocketsController < WebsocketRails::BaseController
  def create
    send_message :new_event, {:message => 'TEST'}
  end
end

events.rb

WebsocketRails::EventMap.describe do
  subscribe :new_event, 'sockets#create'
end

websocket_rails.rb

WebsocketRails.setup do |config|
  config.redis_options = { driver: :ruby }
  config.standalone = false
  config.synchronize = true
end

Client side:

$socket.on('test', function(data) {
console.log(data);
    $scope.events.upshift(data);
if($scope.events.length>50){
$scope.events.length=50;
EventsList =$scope.events;
}
});

routerApp.config(["$socketProvider", function ($socketProvider) {
  $socketProvider.setUrl("http://172.16.20.179:3000/events");
}]);

On the client side issue looks like:

GET http://172.16.20.179:3000/socket.io/?
EIO=3&transport=polling&t=1439215071732-9

XMLHttpRequest cannot load http://172.16.20.179:3000/socket.io/?
EIO=3&transport=polling&t=1439215056291-6. No 'Access-Control-Allow-
Origin' header is present on the requested resource. Origin 
'http://localhost:4000' is therefore not allowed access. The response 
had HTTP status code 404.

It seems that you are trying to use Socket.IO for web-sockets. There are no supported implementation of Socket.IO for Rails.

If you want an example on how to interact with websocket-rails from Angular.JS, you can use, for example, the following guide:
