title: How to put an InlineFormSet into a ModelFormSet in Django?
body: <p>I'd like to display a number of forms via a <code>ModelFormSet</code> where each one of the forms displays in turn <code>InlineFormSets</code> for all objects connected to the object. </p>
  
  <p>Now I'm not really sure how to provide the instances for each <code>ModelFormSet</code>. I thought about subclassing <code>BaseModelFormSet</code> but I have no clue on where to start and would like to know whether this is possible at all before I go through all the trouble.</p>
  
  <p>Thanks in advance!</p>
