Hi guys
I got this weird AsserstionError and KeyError. It says it is ignored.
The class Credential is a mapped as a relation to the parent class.
credential=relation(Credential, \
primaryjoin=id == Credential.n_id,\
foreign_keys=[Credential.n_id],\

Hi all,
i am new to SQLAlchemy (simply wonderful!), and i'm writing some
python scripts to do some experiment.
I've written a SINGLE python module with two classes which define two
different tables (declarative_base) with a simple relationship and a
single Foreign Key and everything WORKS fine

Thanks, that's perfect. I knew it had to be in the API somewhere, but
I couldn't find it.

Hello,
I am stuck here with a query, it't not too complicated I think, but I dont
get it...
I have three Class/table mappings:
Shots, Assets, which belong to a Shot (1:n) and AssetCategories, which are
owned by Assets (n:1)
The objective is:
For a given shot instance get all distinct
Thanks that worked beautifully.
On a similar note, how would I match documents with only the tags that
I specify in the list? My naive attempt is:
for tag in tag_list:
session.query(Document).join(Document.tags).filter_by(tag=tag)
But that doesn't work.

I am running into the following error running under mod_wsgi, and
against an Oracle Database, using cx_Oracle
I'm running the following query:

The table is defined as follows:
that should be fixed in latest tip. get it from the download page.

Hi,
I have a query object to which I'm performing the following join and
filter:
Q = Q.outerjoin(Table.history_loader)
Q = Q.filter(TableHistory.tick == 123)
Table.history_loader is a dynamic loader that maps the two tables
based on their id property.
This produces the following

Did you try
qry =
session.query(AssetCategory).join(Asset).join(Shot).filter(Shot.id==1).distinct()
qry = qry.filter(Shot.id==shot_id_of_interest)
that generates
SELECT DISTINCT AssetCategory.id AS AssetCategory_id
FROM AssetCategory JOIN Asset ON AssetCategory.id =
Asset.category_id JOIN Shot
