I wonder what is best practice to store relations in GAE with datastore.

If I have User and UserItem. How should I store reference to User inside UserItem?

Should I store:

  • hashed key value (eg: ag1taWNlM2hlZGdlaG9ncg8LEglMZXZlbFVzZXIYSAw)
  • unhashed key value (eg: User(“1”) )
  • any other suggestion?

    In java you would use the Key property to store a reference to another datastore object.
