hasOne + belongsTo without id in the child

user548 Published in April 22, 2018, 10:05 pm

I would like to model a one to one relation in grails (2.4.2).

I do it as described in the documentation like:

class Face {
    static hasOne = [nose: Nose]

class Nose {
    static belongsTo = [face: Face]

everything is fine, well, nearly...

Now I have 2 fields (id and face_id) "in the Nose".

I would like to have the face_id as the primary key of the Nose.

I would like to suppress the "normal" ID field in the Nose. The face_id field is enough as the key.
