Symfony 2/Doctrine - set value of forgein key - symfony

Question

I had a problem like here. I followed the instructions of given solutions, but it generate another problem.
I've got two Entities:

So I want to use this code to insert data to table:
$mecz = new Mecz();
$mecz->setId($id_meczu);
$typs = new Typy();
$et = $this->getDoctrine()->getManager();
$typs->setIdKuponu($id_kuponu);
$typs->setMeczid($mecz);
$typs->setTyp($typ);
$typs->setStawka($stawka);
$et->persist($typs);
$et->flush();
And i get exception:
An exception occurred while executing 'INSERT INTO Mecz (id, druzyna1, druzyna2, bramki1, bramki2, wyniktyp, data, typ1, typ1x, typ2, typ2x, typx) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)' with params ["2", null, null, null, null, null, null, null, null, null, null, null]:
I don't know why, because i want to instert data to "Typy" table not "Mecz" table. Can anyone could help me?

Answer 1

The problem is the following:
You have the field Typy::meczid, but this field does (from the perspecitve of Doctrine) not hold a numeric ID, but a reference to a Mecz instance. Therefore the name meczid is misleading, it should be Typy::mecz. I'd recommend renaming the field and the accessors for the sake of consistency.
Now the Typy entity expects a Mecz entity to be set, which you do: You create a new Mecz(), and assign it to Typy with $typs->setMeczid($mecz);. BUT: The Mecz instance is lacking lots all properties except the ID. (By the way, in Doctrine IDs should generally be autogenerated, not by the business logic.) As the Typy entity depends on Mecz, the Mecz must be persisted first, so its reference can be stored with the Typy.
Bottom line: You must fill the generated Mecz with the missing properties.
Hint: To avoid that this type of error happens on the DB level, you should use Symfony's entity validation component. This will allow a much better error handling; both during development, and in production.
