Ok, i've tried both (and each separately), as in:
r1 = Report(number = 1, title = "The Bird")
r2 = Report(number = 2, title = "The Bucket")
session.add_all([r1, r2])
session.commit()
q = self.session.query(Report.title)
q.with_entities(Report.number)
q.add_columns(Report.number)
print q.all()
printing:
[(u'The Bird',), (u'The Bucket',)]
what i would like to see is:
[(u'The Bird', 1), (u'The Bucket', 2)]
or something similar.
Cheers, Lars
