JHipster: Error: In the relationship between Image and ImageType, ImageType is not declared

Question

JHipster: Error: In the relationship between Image and ImageType, ImageType is not declared.

entity Image {
}
enum ImageType {
   MAIN
}
relationship OneToOne {
    Image{type} to ImageType
}

How to implement unidirectional one to one?

Answer 1

I think instead of having unidirectional one-to-one relationship, you want ImageType to be a field of Image :

enum ImageType {
    MAIN
}
entity Image {
    type ImageType
}

If for some reason you actually want one-to-one relationship, you need to use your enum in an entity :

enum ImageType {
    MAIN
}
entity ImageTypeEntity {
    type ImageType
}
entity Image {
}
relationship OneToOne {
    Image{imageTypeEntity} to ImageTypeEntity
}
