title: Braintree Hosted Fields Example
body: <p>I am trying to get my head round the Hosted Fields framework of Braintree. It has been released just a few days ago and is still in beta.</p>
  
  <p>I looked at the docs. I'm getting the overall idea but it would be nice to have some sort of small working example to start with. I found a <a href="https://github.com/developersteve/ruby-braintree-hosted-fields">github repo</a> but the code does not seem to be working.</p>
  
  <p>Google search did not deliver anything of value (just articles commenting on the idea). Can you point me to a working example (preferably one using rails) ?</p>
