  <p><code>descriptor 'date' requires a 'datetime.datetime' object but received a 'datetime.date'</code></p>
  
  <pre><code>from datetime import date, datetime, time, timedelta
  
  instance = Model.objects.get(pk=id)
  
  datetime = datetime.combine(datetime.date(instance.mydate), datetime.time(instance.mytime))
  </code></pre>
  
  <p>Edit:</p>
  
  <p>mydate and mytime are stored here:</p>
  
  <pre><code>class Model(models.Model):
      mydate = models.DateField(blank=True, null=True)
      mytime = models.TimeField(blank=True, null=True)
  </code></pre>
  
  <p>Edit 2:</p>
  
  <p>I did have this in place but was looking for a 1 line solution:</p>
  
  <pre><code>mydate = datetime.strptime(str(instance.mydate), '%Y-%m-%d')        
  mytime = datetime.strptime(str(instance.mytime), '%H:%M:%S')        
  datetime = datetime.combine(datetime.date(mydate), datetime.time(mytime))
  </code></pre>
