Repository->findBy( ) gives back a *collection *of entities. So you'll have
to loop over them to set their fields. If you are shure you'll only
get/want at most 1 entity back you can use Repository->findOneBy( ).
Repository->find( ) searches in a primary key, so it can only get at most 1
entity back. EntityManager->find ( ) is just a shortcut for
Repository->find( ).
You are still mainly thinking in tables and records. Why are you using an
ORM? For if you want to update tables and records, it would probably be
easier to just write SQL directly, without Doctrine. No critic, just
wondering.
