Doctrine Query reverse join?

  doctrine, doctrine-orm, doctrine-query, symfony

BDD Schema

I have these relations.

I need to retrieve all contents but order by star.content_Idcontent first.

It works with easy SQL:

SELECT content.idcontent
FROM content
LEFT JOIN star ON content.idcontent = star.content_Idcontent 
ORDER BY star.content_Idcontent DESC,content.idcontent

But I don’t know how to do it with Doctrine because content is not the owner of the relation.

Must I create a bidirectional relation or is there a way to make it work?
