title: Django prefetch_related cache not reflecting the changes
body: <p>I have a model <strong>Banks</strong>. and I have <strong>six entities</strong> in it.</p>
  
  <p>This is my prefetch code.</p>
  
  <pre><code>queryset = Banks.objects.all().prefetch_related('field1','field2')
  </code></pre>
  
  <p>when I enter new entity into my Banks model and get the data, I still get only the old data. The newly added entity is not getting reflected when I download the data.</p>
