I'm trying to delete User entity from DB
//whatever
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "user", orphanRemoval = true)
private Set<Filter> filters = new HashSet<Filter>();
//whatever
//whatever
@ManyToOne(fetch = FetchType.LAZY, cascade = {CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH, CascadeType.DETACH})
@JoinColumn(name = "user_id", nullable = false)
private User user;
//whatever
but getting: ERROR SqlExceptionHelper:146 - Cannot delete or update a parent row: a foreign key constraint fails ( web_app_db
. filters
, CONSTRAINT FK_8oeay5yddrcgd4i71m1yda1hb
FOREIGN KEY ( user_id
) REFERENCES users
( user_id
))
orphanRemoval = true not working, what should I do?
Try this:
@ManyToOne(fetch = FetchType.LAZY, cascade = {CascadeType.ALL})
@JoinColumn(name = "user_id", nullable = false)
private User user;
