title: How to obtain a QuerySet of all rows, with specific fields for each one of them?
body: <p>I have a model <code>Employees</code> and I would like to have a QuerySet of all rows, but with some specific fields from each row, and not all fields.</p>
  <p>I know how to query all rows from the table/model:</p>
  <pre><code>Employees.objects.all()
  </code></pre>
  <p>I would like to know how to select fields for each of the Queryset element. How can I do that?</p>
