Question

Say that I have a model like this:

User(db.Model):
  name = db.StringProperty()
  interests = db.StringListProperty()

The document, “How Entities and Indexes are Stored – Google App Engine — Google Developers”, describes how they stored index.

And I’d like to get all unique interests among the users without fetching all users.

EDIT: I mean that getting unique set of interests.

Answer 1

The Gql query allows you to add a property list, so you can use:

"SELECT interest FROM User"
