title: Can I have a Django model that has a foreign key reference to itself?
body: <p>Okay, how would I do this?</p>
  
  <pre><code>class Example(models.Model):
    parent_example = models.ForeignKey(Example)
  </code></pre>
  
  <p>I want to have a model have a foreign key reference to itself.  When I try to create this I get a django validation error that Example is not yet defined.</p>
