How to Push to Faye Server from Rails Controller

How can I push to Faye Server from Rails Controller?

I did't use Event Machine but I use Fay-web Socket in rails , I am using thin web-server for my application to show notification.

First you add this line into you Gemfile

gem 'faye'
gem 'thin' 

Now ! run bundle install command for install gem and it's
dependency.

Create a faye.ru file and add given line (a rackup file for run
Faye server ).

require 'rubygems'
require 'thin'
require 'faye'
faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 45)
run faye_server

Now add line to your application.erb file

<%= javascript_include_tag 'application', "http://localhost:9292/faye.js", 'data-turbolinks-track' => true %>

Create a method with name broadcast or any name which is
suitable for you in websoket.rb (first create websoket.rb file
inside config/initializers ) .

module Websocket
  def broadcast(channel, msg)
    message = {:channel => channel, :data => msg}
    uri = URI.parse("http://localhost:9292/faye")
    Net::HTTP.post_form(uri, :message => message.to_json)
  end
end

Now use this method inside your model or controller where you want.

In my case I am using this inside the **Notification.rb to sending notification.**

Example

after_create :send_notificaton 

def send_notification
    broadcast("/users/#{user.id}", {username: "#{user.full_name }", msg: "Hello you are invited for project--| #{project.name} | please check your mail"})
end

For subscriber

<div id="websocket" style="background-color: #999999;">
</div>
<script>
$(function () {
var faye = new Faye.Client('http://localhost:9292/faye');
        faye.subscribe('/users/<%= current_user.id %>', function (data) {
            $('#websocket').text(data.username + ": " + data.msg);
        });
    });
</script>

Now ! Run your faye.ru file using terminal

rackup faye.ru -s thin -E prodcution

Rails - Faye pushing data

[SOLVED]

faye_server = Faye::RackAdapter.new(:mount => '/faye', :timeout => 45)
faye_server.get_client.publish('/foo', data )

How can I have a server side faye client running within my rails app?

I have solved this now by using the 'faye-rails' gem and included this into my application.rb file:

config.middleware.delete Rack::Lock
config.middleware.use FayeRails::Middleware, mount: '/faye', :timeout => 25 do
    class RealTime < FayeRails::Controller 
        channel '**' do
            monitor :unsubscribe do
                if channel != '/messages' && channel != '/disconnect'
                    user = channel[6..-1]
                    @members = Members.where("username = '#{user}'")
                    data = {:channels => @members, :user => user}
                    RealTime.publish('/disconnect', data)

                    @members.destroy_all
                end
            end
        end
    end
    add_extension(RealTime.new)    
end

I also have a own channel for each user which I use to get the username and delete data from the database.

Checking if the Faye server exists before running it for my Rails app

You can use the DaemonController library. It will enable you to auto-start services with your Rails app, starting them if they aren't already started.
