title: Django and mongo really schemaless
body: <p>I have to write a web app with django and mongo. I choosed mongoengine.
  My db has only one collection with a lot of keys, that can change so for me defining a model like:</p>
  
  <pre><code>from django.db import models  
  
  
  class Article(models.Model):  
      title = models.CharField(max_length = 64)  
      content = models.TextField() 
  </code></pre>
  
  <p>Is really hard. And I think that if I must write a schema model like the above, it isn't a real schema less integratioon, because I have to write down all attributes.
  Any hint?</p>
