+1  A: 

If you use Doctrine in a recent version (I don't know since when this exists), you relationships will be saved when a related object is saved, assuming it the relation has changed. This work without embedded forms (even without form), it's a different thing and part of the ORM.

If this behavior does not work, it's an issue with your model declaration in schema.yml
