title: Django Tasty Pie: serialization on PUT and POST methods
body: <p>I'm building a RESTful app on Django and Tasty Pie. I have a problem with PUT and POST methods. When I do a request via Curl I have an error. </p>
  
  <p>Curl requests: </p>
  
  <pre><code>curl -i -H "Content-Type :application/json" -X POST -d '{"site_id":2,"post":2}' --user log:pass http://domain.com/core/api/v1/bookmarklet_post/
  
  curl -i -H "Content-Type :application/json" -X PUT -d '{"site_id":2,"post":2}' --user log:pass http://domain.com/core/api/v1/bookmarklet_post/
