  pass

User.friends = ndb.StructuredProperty(User, repeated=True)
User._fix_up_properties()

def _fix_up_properties(cls):
    """Fix up the properties by calling their _fix_up() method.
    Note: This is called by MetaModel, but may also be called manually
    after dynamically updating a model class.
    """
