Ao tentar apagar o objecto cliente com o codigo:
EntityManager em = new JPAUtil().getEntityManager();
ContaCliente conta = cliente.getConta();
List<Divida> pagamentos = conta.getPagamentos();
DividaDao dividaDao = new DividaDao(em);
pagamentos.forEach(divida -> dividaDao.apagar(divida.getId()));
ContaClienteDao contaDao = new ContaClienteDao(em);
contaDao.apagar(conta.getId());
ClienteDao clienteDao = new ClienteDao(em);
clienteDao.apagar(cliente.getId());
em.close();
, recebo o seguinte erro:
ERROR: Cannot delete or update a parent row: a foreign key constraint fails (`albamoura`.`divida`, CONSTRAINT `FK_hs7tjqt1eu10ns6c5w56fw3ml` FOREIGN KEY (`conta_id`) REFERENCES `contas` (`id`))
