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 condition and remote_side arguments. Consider using the remote() annotation to accurately mark those elements of the join condition that are on the remote side of the relationship. I've copied my code here https://gist.github.com/silenius/e2c7fb393864b3f1fee8131336dd8b61 Any idea what could be wrong ..? Basically I have a "translation" table and I'd like to JOIN that table for the current translation or the "fallback" language, so something like: select c.id, t.* from content c JOIN LATERAL (select ct.* from content_translation ct WHERE ct.content_id=c.id order by ct.language_id='fr' desc, ct.language_id='en' desc limit 1) as t ON t.content_id = c.id WHERE c.id=4855; Thank you!
