title: Google App Engine Python Datastore
body: <p>Basically what Im trying to make is a data structure where it has the users name, id, and datejoined. Then i want a "sub-structure" where it has the users "text" and the date it was modified. and the user will have multiple instances of this text.</p>
  
  <pre><code>class User(db.Model):
      ID = db.IntegerProperty()         
      name = db.StringProperty()
      datejoined = db.DateTimeProperty(auto_now_add=True)
  
  class Content(db.Model): 
      text = db.StringProperty()
      datemod= db.DateTimeProperty(auto_now_add = True)   
  </code></pre>
  
  <p>Is the code set up correctly? </p>
