}
When I try to save the ContentPlayer with all child entities - everything goes fine, but if I want to add / change some data in the child entity - this leads to an error, although I indicated the cascade.
Error Example:
org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.TransientPropertyValueException: object references an unsaved transient instance - save the transient instance before flushing : com.core.entities.content.Season.series -> com.core.entities.content.Series;
Is it possible to implement saving changes to child objects? Adding each child object individually is not really appropriate.

I have a small project Java Spring Boot, i use Annotation to create field and Table in MySQL, i want to add some other field in a middle table "candidate_tets" to store some other field, then i create a class "CandidateTest". But when i add annotation #Id and #GeneratedValue(strategy = GenerationType.IDENTITY) in var "id", i have a problem, that the AutoIncrement in MySQL and PRIMARY KEY isn't set to column id in MySQL, i don't know the problem in here
this is my Candidate class
#Entity

this is MySQL table *candidate_test* and the problem
Can you guys give me the reason why the AutoIncrement and PRIMARY KEY is not set in this middle table
I think it is because of the Serializable interface try removing that and then re-execute it should work.
I'm using SpringBoot and JPA + Hibernate.
I have these entities:
#Entity
#Table(name = "post")
#AllArgsConstructor #NoArgsConstructor
#Getter #Setter
public class Item extends BaseEntity {
#Id
#Column(name = "id")
#Type(type = "uuid-char")
private UUID uuid = UUID.randomUUID();
#OneToMany(mappedBy = "post", orphanRemoval=true, fetch = FetchType.EAGER)
#MapKey(name="userId")
private Map<UUID, Share> shares;
....
#CreationTimestamp
#Column(name = "creation_date")
#Setter(AccessLevel.NONE)
private Instant creationDate;
#UpdateTimestamp
#Column(name = "last_mod_date")
#Setter(AccessLevel.NONE)
private Instant lastModificationDate;
}
#Entity
#Table(name = "comment"
#AllArgsConstructor #NoArgsConstructor
#Getter #Setter
public class Comment extends BaseEntity {
#Id
#Column(name = "id")
#Type(type = "uuid-char")
#Setter(AccessLevel.NONE)
private UUID uuid = UUID.randomUUID();
#ManyToOne(fetch = FetchType.LAZY)
#NotNull()
#JoinColumn(name = "post_id")
private Post post;
.....
#CreationTimestamp
#Column(name = "creation_date")
#Setter(AccessLevel.NONE)
private Instant creationDate;
#UpdateTimestamp
#Column(name = "last_mod_date")
#Setter(AccessLevel.NONE)
private Instant lastModificationDate;
}
#Test
#Transactional
public void testDeleteItem() {
itemRepo.delete(item);
itemRepo.flush();
}
When I try to delete a parent entity (Post), all related entities Comments remains on the database.
Why doesn't works the cascade deletion?
OrphanRemoval doesn't work. Use cascade = CascadeType.ALL instead
I have next classes:
#Entity
#Table
public class Lesson implements ModelEntity {
#Id
#Column(name = "lesson_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "course_id")
private Course course;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "lesson_type_id")
private LessonType lessonType;
private LocalDate date;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "time_slot_id")
private TimeSlot timeSlot;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "auditorium_id")
private Auditorium auditorium;
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable(name = "lesson_teacher", joinColumns = #JoinColumn(name = "lesson_id"), inverseJoinColumns = #JoinColumn(name = "person_id"))
private Set<Teacher> teachers = new HashSet<>();;
#ManyToMany(fetch = FetchType.LAZY)
#JoinTable(name = "lesson_group", joinColumns = #JoinColumn(name = "lesson_id"), inverseJoinColumns = #JoinColumn(name = "group_id"))
private Set<Group> groups = new HashSet<>();
}
#Entity
#Table(name = "groups")
public class Group implements ModelEntity {
#Id
#Column(name = "group_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name = "group_name")
private String name;
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "faculty_id")
private Faculty faculty;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "group")
private List<Student> students;
}
#Entity
#Table
public class TimeSlot implements ModelEntity {
#Id
#Column(name = "time_slot_id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
#Column(name = "time_slot_number")
private Integer number;
#Column(name = "time_slot_name")
private String name;
#Column(name = "time_slot_start")
private LocalTime startTime;
#Column(name = "time_slot_end")
private LocalTime endTime;
}
I wrote method, that find all Groups_id by Date and TimeSlot_id not connected to Lesson with CriteriaBuilder API, it works perfect:
#Override
public Set<Integer> getBusyGroupsId(int lessonId, LocalDate date, int timeSlotId) {
logger.debug("getBusyGroupsId() with agruments {}, {}, {}.", lessonId, date, timeSlotId);
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Integer> query = criteriaBuilder.createQuery(Integer.class);
Root<Lesson> root = query.from(Lesson.class);
List<Predicate> predicates = new ArrayList<>();
Join<Lesson, TimeSlot> timeSlotJoin = root.join("timeSlot", JoinType.LEFT);
predicates.add(criteriaBuilder.equal(timeSlotJoin.get("id"), timeSlotId));
predicates.add(criteriaBuilder.equal(root.get("date"), date));
if (nonNull(lessonId)) {
predicates.add(criteriaBuilder.notEqual(root.get("id"), lessonId));
}
query.where(predicates.toArray(new Predicate[] {}));
SetJoin<Lesson, Group> joinGroup = root.joinSet("groups");
query.multiselect(joinGroup.get("id"));
TypedQuery<Integer> result = entityManager.createQuery(query);
return result.getResultStream().collect(Collectors.toSet());
}
But after that I think- what about JPA, can it be easier?
I tried something like that, but it doesnt work:
public Set<Integer> findGroupIdByIdNotAndDateEqualsAndTimeSlotIdEquals(Integer lessonId, LocalDate date, Integer timeSlotId);
How to fix it?
Also I stacked with writing method with JPA that should find all Lesson by Group_id and Date(or startDate-endDate) and sort it: first by date, second- by TimeSlot_number.
Can it be written with JPA?
Thanks in advance.
Don't throw stones, I'm just getting to know Spring JPA.
I am getting Data from MySql using Spring Data JPA. I getting this error when I am passing provider as 1465 in request.
I have tried Sending Set from the request as well.
My calling code is :
offerList = blackholeDetailRepository.findByProductVMS(ProductType.VMS, blackholeID,
pricingCopyRequestBO.getProviderId().longValue(),
OfferGradeConstant.fromString(pricingCopyRequestBO.getOfferGrade()));
Code in repository is :
#Query("SELECT detail FROM #{#entityName} AS detail JOIN FETCH detail.vmsRestrictedProviders AS provider "+
"WHERE detail.product = :product " + "AND detail.master.id= :masterId "
+ "AND detail.vmsRestrictedProviders = :providerId " + "AND provider.offerGrade= :offerGrade")
Set<BlackholeDetailEntity> findByProductVMS(#Param("product") ProductType product, #Param("masterId") Long masterId,

I following have hibernate entities:
#Entity
#Table(name = "News")
public final class News implements Serializable, IEntity {

#JoinTable(name = "NEWS_AUTHOR", joinColumns = { #JoinColumn(name = "NEWS_ID") }, inverseJoinColumns = { #JoinColumn(name = "AUTHOR_ID") })

And the second:
#SequenceGenerator(name = "COMMENTS_SEQ", sequenceName = "COMMENTS_SEQ")
#Entity
#Table(name = "Comments")
public class Comment implements Serializable, IEntity {

private Long newsId;
#NotEmpty
#NotNull
#Column(name = "COMMENT_TEXT")
private String commentText;
#Temporal(TemporalType.DATE)
#Column(name = "CREATION_DATE")
private Date creationDate;
When I'm trying to remove entity News, I get the exception ORA-02292: integrity constraint (ROOT.SYS_C007062) violated - child record found. So, if I remove the property "updatable = false" it tries to set nullable fields into property Comment. What is my mistake? Please, help.
Thanks.
Because your news records have a one to one or one to many relation with comments. You most likely did not specifcy a CACASDE ON DELETE clause while defining your table. in order to delete entity NEWS you have to make sure that all of its related comments records are deleted or are referencing another NEWS record.
basicaly the definition of the ORA 02292 exception.
