I have the following entity:

@Entity
@Table(name = "calendar")
public class Calendar {
    @Id 
    @GeneratedValue(generator = "uuid2")
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    @Column(name = "id", columnDefinition = "BINARY(16)")
    private UUID id;

    @Column(name = "name")
    private String name;

    @JsonIgnore
    @ManyToOne(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinColumn(name = "owner", referencedColumnName = "id")
    private OrganizerUser owner;
    ...
}

If I insert an object of that class into the table, everything works fine. However, when I add the following to the entity:

@Column(name = "owner", updatable = false, insertable = false)
private UUID ownerId;

I get the following error:

Cannot add or update a child row: a foreign key constraint fails (`organizer`.`calendar`, CONSTRAINT `FK3f7d9mholcykdaygm3bnwhwg7` FOREIGN KEY (`owner`) REFERENCES `user_info` (`id`))

Is it possible to have a reference to the foreign key in this scenario? If I omit the reference and just do owner.getId(), will the OrganizerUser object be loaded?
