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
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
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
