W skrócie. Dodaje własne sprawdzenie walidacji pola formularza. Korzystam z Form i walidacji Symfony poprzez adnotację. W funkcji walidacji potrzebuję dostęp do bazy danych. W tym celu do konstruktora klasy dziedziczącej po ConstraintValidator podaje obiekt klasy EntityManagerInterface i przetrzymuję w zmiennej $entityMan. Następnie w funkcji validate tej klasy staram się wyszukać za pomocą findOneBy() obiekt(wiersz w bazie danych) w którym wartość email równa się wartości $value przekazanej do funkcji validate. Jednak otrzymuje błąd ORMException "Unrecognized field: email". Dodam, że w klasie User oraz w bazie danych takie pole istnieje i ma tą samą nazwę. Proszę o wskazówkę gdzie może być błąd.
