Hello,
qry =
session.query(AssetCategory).join(Asset).join(Shot).filter(Shot.id==1).distinct()
this one already did the trick.
qry = qry.filter(Shot.id==shot_id_of_interest)
what did you add this for? The results seem to be identical...
that generates
SELECT DISTINCT "AssetCategory".id AS "AssetCategory_id"
FROM "AssetCategory" JOIN "Asset" ON "AssetCategory".id =
"Asset".category_id JOIN "Shot" ON "Shot".id = "Asset".shot_id
WHERE "Shot".id = :id_1
Here it generates:
SELECT DISTINCT "AssetCategory".id AS "AssetCategory_id",
"AssetCategory".name AS "AssetCategory_name"
FROM "AssetCategory" JOIN "Asset" ON "AssetCategory".id =
"Asset".category_id JOIN "Shot" ON "Shot".id = "Asset".shot_id
WHERE "Shot".id = :id_1
This leads to my next question: where does sqlalchemy know from on which
column to use the distinct expression (apart from using the primary key?).
I am using sqlalchemy 0.5.8, perhaps there is a difference?!
Thanks
Sebastian
