Oh, sorry, i supposed thaty contains_eager only worked for relationships,
and not for other kind of attributes :D
That's great!
Thanks!

what additional behaviors are you looking for that the @property approach isn't
giving you ? Options include turning it into a synonym() which would allow
it to be a little bit more transparent.

Hi,
Sorry to insist on this :P
But there is any way to get this kind of behaviour, the "virtual"
column/relationship?
Thanks!

Hi Michael,
As always, thank you very much for your dedication :)
I recognize that I am always trying to reach the edges of your wonderful
library.
That example is just a sample of what I am trying to accomplish:

Hi,
I have prepared a sample of code to ilustrate this behaviour :)
Summarizing:
session.expunge_all()
n2 =
session.query(Node).filter_by(name='n2').options(joinedload('ancestors')).one()
print n2.ancestors
AND:
session.expunge_all()
n2 = session.query(Node).filter_by(name='n2').one()
n2 =
se
Ok, thank you very much :D
I'll keep poking, and i'll try to provide a sample code :P

Hi!
I have a tree structure modeled into a database using adjacency-list

I'm adding some custom rela
