title: Django: Is it possible to filter on QueryDict?
body: <p>Within my <code>form.data</code> I have a QueryDict.</p>
  
  <pre><code>    QueryDict: &lt;QueryDict: {u'deal_status_2': [u'1'], 
                       u'deal_status_1': [u'2'], u'subject': [u'wdes']}&gt;  
  </code></pre>
  
  <p><code>deal_status_1</code> and <code>deal_status_2</code> are both dynamically generated as part of the form through jquery.</p>
  
  <p>Nowhere else on the POST form could I find them but in form.data.</p>
  
  <p>Which is fine, now I need the values.</p>
  
  <p>So I thought it would be great if I could filter on QueryDict like this</p>
  
  <pre><code>var array = form.data.filter(???__istartswith('deal_status_')
  </code></pre>
  
  <p>and get an array of all the dynamically generated fields I need to iterate through and grab the value from.</p>
  
  <p>Is this possible?  what do I put for <code>???</code> in there?</p>
