title: How to create short uuid with Django
body: <p>I have a model and UUID as primary key field. UUID id is way too long. I'd like to have it short similar to YouTube.</p>
  
  <pre><code>class Video(models.Model):
      id = models.UUIDField(
          primary_key=True, 
          default=uuid.uuid4, 
          editable=False,
      )
  </code></pre>
  
  <p>Instead of this</p>
  
  <pre><code>UUID('b39596dd-10c9-42c9-91ee-9e45b78ce3c1')
  </code></pre>
  
  <p>I want to have just this</p>
  
  <pre><code>UUID('b39596dd')
  </code></pre>
  
  <p>How can I achieve above?</p>
