Question

How can I modify this

 videos = Video.gql( 'WHERE user_id = :1', '18' ).fetch(8)

so that instead of matching for a user_id, it returns any of the last 8 Video objects added to the datastore?

Answer 1

You should save your models with a

created = db.DateTimeProperty(auto_now_add=True)

for this type of queries.

The accepted answer on this question is not correct. If you add a created property to your models and compare queries ordered by -created and -__key__ you will see that they don’t match.

Keys that are automatically set will not be monotonically increasing. Some good read on that here .
