For example when I'm doing dbsession.get(MyClass, 1234) I cannot figure
how reference the id in the column_property query
Any idea ?

Hello,
I'm trying to add a 'read-only' relationship involving a subquery and I
have some problems with remote and foreign sides, SQLAlchemy returns:
sqlalchemy.exc.ArgumentError: Relationship Folder.current_translation could
not determine any unambiguous local/remote column pairs based on join
xy, but less flexible and read-only.
OK I'll make a separate property, I had some vague idea about using some
QueryEvents to manipulate the query, but it sounds a bit complicated and
hazardous

if you can try to
reproduce with a test case that would be helpful.

Hello,
Any idea why the following doesn't work ? :
Topic2= orm.aliased(Topic)
q= Occurrence.query.\
join(Occurrence.datasheet).\
options(orm.contains_eager(Occurrence.datasheet)).\
join(Topic2).\
options(orm.contains_eager(DataSheet.topic,alias=Topic2)).\
),
orm.contains_eager(Species.datasheet, alias=Foo),
orm.contains_eager(Site.datasheet, alias=Foo),
orm.contains_eager(Occurrence.species, Occurrence.site)
)
but it doesn't seems to work ...
Any idea ? :)
Thank you,

SQLAlchemy generates a subquery for the outer join.
Any idea how to ask SQLAlchemy to generate a shorter

Hi Julian,
Thanks, I am looking into it and it looks interesting. Have you done
much testing yet? How do you (plan to; haven't looked at too much
detail yet) check for circular references (like backrefs)?
circular references aren't handled yet
Hello,
I'm using SQLAlchemy 0.7.6 and PostgreSQL 9.0.7 which support a FOR
UPDATE and a FOR SHARE clause to lock selected rows.
I noticed that the .with_lockmode() method of the Query object
has only FOR UPDATE and FOR UPDATE NOWAIT at the moment,
easy enough to add more options though it would be helpful if someone could volunteer a patch on it
(with tests as always!):

Hello,
Is there a reason why a .count() on a Query object doesn't (LEFT) JOIN
all the relations marked with lazy='joined' in the Mapper?
I guess it's to avoid unnecessary JOINs, but sometimes it can lead to
strange results if the relation is marked with innerjoin=True, for example:
q =

the COUNT and the second one the full query)

Hello,
I upgraded to 0.7.4 together with PostgreSQL 9.0.5.
I have a database with several schemas, and it looks like the handle of

Using FLOAT for monetary amounts is an extremely bad idea because of the
inexactness of storage and arithmetic ..
Using MONEY is discouraged because it is too locale-sensitive
NUMERIC should be used instead

don't use the MONEY type in PostgreSQL, use NUMERIC instead.
