title: Django generates 'WHERE ... BETWEEN ...' sentences?
body: <p>Actually, somewhere in the view:</p>
  
  <pre><code>dif = datetime.timedelta(days=1)
  today = datetime.date.today()
  yesterday = today - dif
  ex = Fact.objects.filter(fecha_fact__lte=today ,fecha_fact__gte=yesterday )
  </code></pre>
  
  <p>It results to this SQL Query:</p>
  
  <pre><code>SELECT `facts_fact`.`id` ...
  FROM `facts_fact` 
  WHERE (`facts_fact`.`fecha_fact` &gt;= 2009-09-21 AND `facts_fact`.`fecha_fact` &lt;= 2009-09-22 ) 
  </code></pre>
  
  <p>There is a way to make Django do a WHERE BETWEEN sentence instead >= &lt;= ?</p>
  
  <p>:) thx.</p>
