gorm version

gorm.io/driver/sqlite v1.5.3
gorm.io/gorm v1.25.4

Description

When using has many Foreign Key, i can create a reverse field by refereneces

type Disk struct {
    UUID string `gorm:"primaryKey"`
    Instance    *Instance `gorm:"references:Name"`
    InstanceName *string
}

type Instance struct {
    UUID string `gorm:"primaryKey"`
    Name string
    Disk []Disk `gorm:"foreignKey:InstanceName;References:Name"`
}

But if i change the InstanceName to another one like IntanceOwner, it wont work

type Disk struct {
    UUID string `gorm:"primaryKey"`
    Instance    *Instance `gorm:"references:Name"`         // <-- comment out this works 
    InstanceOwner *string          // <-- Name change from InstanceName to InstanceOwner
}

type Instance struct {
    UUID string `gorm:"primaryKey"`
    Name string
    Disk []Disk `gorm:"foreignKey:InstanceOwner;References:Name"`
}
func main() {
    db, err := gorm.Open(sqlite.Open("a.db?_foreign_keys=on"), &gorm.Config{})
    if err != nil { panic(err) }
    err = db.AutoMigrate(&Instance{}, &Disk{})
    if err != nil { panic(err) }
}

will got following erro
