title: Ajaxful-rating alternative Lets-rate rails gem needs ajax
body: <p>I need this <a href="https://www.ruby-toolbox.com/categories/rails_ratings#letsrate" rel="nofollow">https://www.ruby-toolbox.com/categories/rails_ratings#letsrate</a> plugin to have ajax. I have to logout and login every time I rate to see the results. Example app is here <a href="http://letsrate.herokuapp.com/" rel="nofollow">http://letsrate.herokuapp.com/</a> 
  How can I make it update results instantly? ThankS</p>
