title: How to get the formatted POST data of a Django form?
body: <p>I have a Django ModelForm but don't want the user to click on a reguar submit button.
  Instead, I made my own submit button and will post the form data using Ajax/jQuery.
  The data to post is a mix of the form data plus other information I gather on my UI.
  But... how do i get the formatted POST data the html form was supposed to submit?
  If I can get it like JSON or jQuery object, better!</p>
