title: Django showing the result of a query with decimal()
body: <p>Hello I have a question about the result of a query.</p>
  
  <pre><code>suma = Contrato.objects.aggregate(Sum('lote__Costo'))
  </code></pre>
  
  <p>The result is the sum of all the records in a column of the database.</p>
  
  <p>What I can not understand exactly is the way in which I get the result of the query which is shown as follows</p>
  
  <pre><code>{'lote__Costo__sum': Decimal('142000.00')}
  </code></pre>
  
  <p>Is equal in the shell as in the template I wonder if there is a way to display only the result of the query.</p>
  
  <p>Thanks.</p>
