At server side, in js.erb file you will have to broadcast message to a channel. ie

<% broadcast "/messages/new" do %>
  $("#chat").append("<%= escape_javascript render(@message) %>");
<% end %>

To broadcast the message/data from controllers. ie

def create
  respond_to do |format|
    format.json do 
      broadcast "channel" do 
         @message.to_json
      end 
    end
  end
end

At client side you will have to include the faye javascript in layout or template and will have to subscribe the channel. ie

<%= javascript_include_tag :defaults, "http://localhost:9292/faye.js" %>

and a dom container in layout or template. ie

<ul id="chat">
  <%= render @messages %>
</ul>

and Subscribe the channel via javascript. ie

$(function() {
  var faye = new Faye.Client('http://localhost:9292/faye');
    faye.subscribe("/messages/new", function(data) {
    eval(data);
  });
});

[SOLVED]

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