why do i get an exception starting springdata rest api
Question
Ive a little issue with my basic rest, crud api. My app works well but only when I dont have any field in my model which is object made by me. My video cassett model has Long id, String title and Genre genre and this genre is problematic. Genre has Long id, String title and String description. Unfortunately I cant post my casset using Json in postman because I want to send genre by its name. So I came up with the solution that I post CassetCreator instead of Casset. My CassetCreator is same as Casset but has genre which is String. So I post object, take its attribute and using jpa search genre by its name and then create Casset that I save manually. The problem is that when I do that, spring boot suddently throws exception that I cannot drop a table ... because it depands on ... Any solution from the internet doesnt work for me, so I want to ask you. Thanks in advance.
Models
import java.time.LocalDate;
@Entity
public class VideoCasset {
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Id
private Long id;
private String title;
private LocalDate productionYear;
@ManyToOne
private Genre genre;
public VideoCasset() {
}
public VideoCasset(String title, LocalDate productionYear, Genre genre) {
this.title = title;
this.productionYear = productionYear;
this.genre = genre;
}
public Genre getGenre() {
return genre;
}
public void setGenre(Genre genre) {
this.genre = genre;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public LocalDate getProductionYear() {
return productionYear;
}
public void setProductionYear(LocalDate productionYear) {
this.productionYear = productionYear;
}
}
import javax.persistence.Entity;

@Entity
public class Genre {
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Id
public Long id;
public String title;
public String description;
public Genre() {
}
public Genre(String title, String description) {
this.title = title;
this.description = description;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;

public Long getId() {

}
public void setId(Long id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
My problematic method
@PostMapping
public VideoCasset addCassett(@RequestBody CassetCreator cassetCreator) {
String title = cassetCreator.getTitle();
LocalDate data = LocalDate.parse(cassetCreator.getData());
String genreName = cassetCreator.getGenre();
Genre genre = genreManager.findByTitle(genreName);
VideoCasset videoCasset = new VideoCasset(title, data, genre);
return cassetVideos.save(videoCasset);
}
and the exception

Try to make a backup of whole database and then drop it ( or point to new database in your application properties)
Create it anew and let hibernate create whole table structures from scratch
From logs it looks like there was some previous structure with existing data
Cannot drop "GENRE" because "FK95K03D6B117EMKR21KIGQAUKA" depends on it
Hibernate failed to upgrade data structure to new one trying to drop some table with aready existing links and recreating it.
