title: Select the latest updated comment in the template
body: <p>I have such a model table</p>
  
  <pre><code>class Comment(models.Model):
      STATUS = (
          (1,  'normal'),
          (0, 'deleted'),
      )
      owner = models.ForeignKey(User, on_delete=models.CASCADE)
      article = models.ForeignKey(Article, on_delete=models.CASCADE)
      body = models.TextField() # set the widget
      status = models.IntegerField(choices=STATUS)
      date_created = models.DateTimeField(auto_now_add=True)
      date_updated = models.DateTimeField(auto_now=True)
  
      class Meta:
          ordering = ('-date_created',)
  
      def __str__(self):
          return self.body
  </code></pre>
  
  <p>I'd like to select the latest updated comments in the template:</p>
  
  <pre><code>{% for comment in article.comment_set.all() %}
     {% if comment.date_updated is the latest %}
         {{ comment.date_updated | timesince}}
  {% endfor %}
  </code></pre>
  
  <p>Is it possible to achieve this in template?</p>
