title: Can I Make a foreignKey to same model in django?
body: <p>Assume I have this model :</p>
  
  <pre><code>class Task(models.Model):
      title = models.CharField()
  </code></pre>
  
  <p>Now I would like that a task may be relates to another task. So I wanted to do this :</p>
  
  <pre><code>class Task(models.Model):
      title = models.CharField()
      relates_to = ForeignKey(Task)
  </code></pre>
  
  <p>however I have an error which states that Task is note defined.
  Is this "legal" , if not, how should I do something similar to that ?</p>
