Witam a więc mój problem polega na tym ze potrzebuje dodać Samochód który zawiera pole obce łączące obiekt relacją @OneToOne z innym obiektem. Problem polega na tym, że nie wiem jak za pomocą thymeleafa dodać to pole jęzeli jest typu obiektowego. Probuje dodać numer z listy i wyskakuje mi błąd Field error in object 'car' on field 'parkingSpace': rejected value [10]; codes [typeMismatch.car.parkingSpace,typeMismatch.parkingSpace,typeMismatch.pl.pw.Parking.parking.Parking,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [car.parkingSpace,parkingSpace]; arguments []; default message [parkingSpace]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'pl.pw.Parking.parking.Parking' for property 'parkingSpace'; nested exception is java.lang.IllegalStateException: Cannot convert value of type 'java.lang.String' to required type 'pl.pw.Parking.parking.Parking' for property 'parkingSpace': no matching editors or conversion strategy found]] Mój kod wygląda tak:
@Entity
@Table(name="cars")
public class Car {
@Id

@Column
private String brand;
