title: Create a Custom History in Django showing specific field changes
body: <p>Heyho,</p>
  
  <p>in Django i want to create a history view of my model 'application' which shows a table with the columns: Who (changed), When, which field, old Value, new Value</p>
  
  <p>I found the <a href="https://django-simple-history.readthedocs.io/en/latest/" rel="nofollow noreferrer">django-simple-history</a> app which stores every version of a model instance in a new model. Actually excactly what i need, but i do not know, how to get the fields of a historical object and especially just the fields which changed comparing two sequenced historical objects. </p>
  
  <p>Has anybody an idea or maybe a complete new approach for that?</p>
  
  <p>Thanks a lot!</p>
