title: Adding 'vote' buttons to django objects
body: <p>At the moment I have multiple 'Photo' objects being displayed on a pages template.</p>
  
  <p>The <code>Photo</code> Model has a field 'score' which has a default value of 0.</p>
  
  <p>I am struggling to find a way to add two buttons ("up"/"down") in the template related to each object so when the "up" button is clicked it adds 1 to that particular Photo objects score, or if "down" is clicked it subtracts 1 from the score and once the button has been clicked it updates the photos score value in the database.</p>
