I think you are using the GORM associations a bit too extensively. belongsTo indicates ownership, and the GORM associations, in general, indicate more about the cascading relationship between objects than anything else.

If you only want to associate User with your Track, you just need to have the createdBy and modifiedBy fields, which don't need to be in any special sort of association. Then you would have static belongsTo = [Course] to show that the Course owns the Track, meaning that if you deleted the Course, that the Track would get deleted as well.

Here's the class I think you are looking for:

class Track {
    User createdBy
    User modifiedBy

    static belongsTo = [Course]
}
