title: Making OmniAuth, Devise and Koala work together
body: <p>I have an app in which I am implementing authentication using devise and omniauth. Ive got the logging in / out etc figured out, what i wanted to know was, what is the most efficient way to have a connection to the users graph api end point initialised and ready for use within my application. </p>
  
  <p>eg: If on the profile page i wanted to do,</p>
  
  <pre><code>profile_image = current_user.fbgraph.get_picture("me")
  </code></pre>
  
  <p>How would I accomplish this with the least number of API calls (i will be using similar calls throughout the application)</p>
