I was trying to use projection queries, but I had extrange issues using
them.
I'm trying to use them like this:
offset_group = Clients.all( \
projection=('name', 'sex', 'birth_date', 'email', 'discount')
).order('-__key__').fetch(limit=10, offset=skip_recs)
The above code is supposed to bring me the last 10 clients. But actually it
does not return the last 10 (actually returns fewer and the actual last
record is not included). Also the results seems alternated or maybe
even/odd are skipped. If I take off projection param, the result is as
spected:
offset_group = Clients.all().order('-__key__').fetch(limit=10,
offset=skip_recs)
I do not know if this is a bug in projection queries or they have to be
used in a different way. Please help me. I would like to use projection
queries because they are really fast!
Kind Regards,
Christopher Ramírez
