title: How to get a single model object using multiple ORM lookup parameters
body: <pre><code>employees = Employee.objects.filter(age=23, sex='female')
  </code></pre>
  
  <p>This would return a queryset.</p>
  
  <p>If I assume this queryset only contains one result, how to return that object directly?</p>
  
  <p>Is there any way like using 'get'?</p>
