Rails way to put localhost in include tags and javascript

Question

I've set up a rails app with faye.

It includes the following code parts:

applications.html.haml:

= javascript_include_tag "http://localhost:9292/faye.js"

discussions.js:

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

When I run the app on localhost in dev mode everything works fine. On the VPS server, it tries to reach my "localhost:9292/faye", when it should be the servers localhost.

Q: Is there a method, or way to get it working with the same code on both the server and localhost? Manually changing to the domain isn't looks the rails way.

Answer 1

you can use:

"#{request.protocol}#{request.host_with_port}/faye"
