I have two models in relation one-to-many:

class Question(db.Model):

questionText = db.StringProperty(multiline=False)

class Answer(db.Model):

answerText = db.StringProperty(multiline=False)

question = db.ReferenceProperty(Question, collection_name='answers')

I have front-end implemented in Flex and use pyamf to load data.

When i try to load all answers with related questions all works as desired and I can access field

answer.question

however in case of loading questions (e.g. by Questions.all() ), 'question.answers' remains empty/null

(though on server/python side I can revise question.answers without problem - probably after lazy-loading).

So is it possible to load all questions along with answers ?

(I know this is possible in JPA Java api but what about python ?)

Shoud I use additional setting, GQL query or django framework to make it work ?
