title: GEODjango: select all objects that are contained in a POST request given polygon
body: <p>my request has coordinates that form a polygon.</p>
  
  <pre><code>plist = []
  ...
  plist.append(fromstr('POINT(%s)' %(value)))
  ...
  p = Polygon(plist)
  </code></pre>
  
  <p>using the GeoDjango I'd like to select all the objects (<code>places.objects.all()</code>) from a table that are contained in the polygon.</p>
  
  <p>going over the documentation I'm finding ways how to verify if a single point intersect or is contained with the polygon (<code>p.mpoly.contains(pnt)</code>)but not something that works on a collection of points</p>
  
  <p>is there a way to achieve that or should I use store procedure for that?</p>
