Hello, what is the preferred way of retrieving the latest revision of a document? (The 'name' doesn't change across the revisions.)
1: class Document(db.Model): name = db.StringProperty() revision = db.IntegerProperty() content = db.TextProperty() latest = Document.all().filter('name =', some_name).order('- revision').get() 2: class Document(db.Model): name = db.StringProperty() class Revision(db.Model): document = db.ReferenceProperty(Document, collection_name='revisions') revision = db.IntegerProperty() content = db.TextProperty() document = Document.all().filter('name =', some_name).get() latest = document.revisions.order('-revision').get() [1] 3: something different altogether? [1] Is it ok to call .get() for the second time? Thanks in advance! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
