Neo4j Spring Boot OGM - saving list of objects in relationship

1
votes

I have an entity "Track" that has a relationship to a list of track objects (TrackObject). I have a list of tracks that I want to save to the Neo4j database and each Track has a list of TrackObjects. Every track gets saved perfectly but only the first TrackObject get saved. Is there a way to save everything directly? Here is the Track:

@NodeEntity (label="Track")
 public class Track {

 @Id
 @GeneratedValue
 private Long id;
 Integer number;
 String name;

 @Relationship (type = "IS_IN", direction=Relationship.INCOMING)
 List<TrackObject> objectList;

I get my list of Tracks and iterate it:

for (Track track : tracks) {
            trackService.saveTrack(track);
            for (TrackObject tobj : track.getObjectList()) {
                trackService.saveTrackObject(tobj);

I also tried with "saveAll" and Iterable and it works for the tracks but not for the list of track objects.

Iterable<Track> tracks = newImport.getTracks();
     trackService.saveTracks(tracks);

What am I doing wrong? Thank you for your answers.

There is a depth property in save function which has a syntax like void save(T object, int depth); Please try this.
