title: Django queryset get all fields in values() plus a foreign key field
body: <p>I have a model with some fields, one of them is a FK. I would like to use</p>
  
  <pre><code>MyModel.objects.all().defer("pk").values()
  </code></pre>
  
  <p>and to add <strong>a field</strong> of my FK (myfk__name) without writing all model fields + 1 in the values.</p>
  
  <p>I also would like to avoid doing another query after this one to add it manually.</p>
  
  <p>Is it possible?</p>
