Google Analytics is used by the vast majority of the internet to monitor traffic. You can quickly and easily add Google Analytics to your Rails application, however there are a few things you should pay attention to. First, make sure that the Analytics code only loads up in a production environment. It’s best to do this by first creating a partial called google_analytics and placing the following code inside of it:

<% if Rails.env == "production"  %>
  <script type="text/javascript">

    var _gaq = _gaq || [];
    _gaq.push(['_setAccount', 'UA-00000000-1']);
    _gaq.push(['_trackPageview']);

    (function() {
      var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
      ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
      var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
    })();

  </script>
<% end %>

This code will tell Rails to only include the Analytics code in a production environment.

So far so good, That’s it!!! See ya!!! :)
