title: most amount of field of day django
body: <p>I want to list the most amounts of field of a model for each day for example this be my model:</p>
  <pre><code>class Topic(Model.models): 
      title = models.Charfield(max_lenth=40)
      total_responses = models.PositiveIntegerField()
      date = models.DateTimeField(add_now=True)
  </code></pre>
  <p>I have imported <strong>Max</strong> before in my <em>views.py</em> and this is my query set:</p>
  <pre><code>query = Topic.objects.values(
              'date','total_responses',
          ).order_by('-date').aggregate(Max('total_responses'))
  </code></pre>
  <p>I am sending this query to <em>template</em>  but it returns all models! but I just need the max amount of <strong>each day</strong> model</p>
