Here's how I would do it:
class Author(db.Model):
""" set the key_name = user_id when you create an Author
instance"""
first_name = db.StringProperty()
last_name = db.StringProperty()
class Post(db.Model):
text = db.TextProperty()
date = db.DateTimeProperty(auto_now_add=True)
author = db.ReferenceProperty(Author, collection_name="posts")
# to get the author:
author = Author.get_by_key_name(users.get_current_user().user_id())
# to get five of the author's posts in reverse chronological order
(like a blog):
posts = author.posts.order("-date").fetch(5)
