title: Django request.POST does not contain the name of the button that submitted the form
body: <p>I have a django form with two different submit buttons, on the view where the form is submitted to I need to know what submit button was pressed and take different actions accordingly. </p>
  
  <p>From what I have read the submit button's name or id should be somewhere in the request.POST dictionary, but it not there! </p>
  
  <p>This is a fragment of my form:</p>
  
  <pre><code>&lt;form id="editPaperForm" action="{{paper.editURL}}" method="POST"&gt;
     &lt;input type="submit" name="savePaperButton" id="savePaperButton" value="Save and Send Later"/&gt;
     &lt;input type="submit" name="sendPaperButton" id="sendPaperButton" value="Save and send"/&gt;
  
     ...
  
  &lt;/form&gt;
  </code></pre>
  
  <p>In the view:</p>
  
  <pre><code>...
  if 'sendPaperButton' in request.POST:
     return applicants_confirmSend(request, paperID)
  else:
     return applicants_home(request)
  </code></pre>
  
  <p>sendPaperButton is never in the request.POST, and neither is the other one, should I be looking somewhere else?</p>
  
  <p>The only idea I have is to add a hidden field and modify it via javascript before sending the form but that seems kind of redundant since I'm pretty sure that data should be there somewhere...</p>
  
  <p>Thanks!</p>
