Gorm After update, the value of the ignored field gorm:"-" in struct is not updated

Your Question

In gorm V1 , the value of the ignored field gorm:"-" will changed after update

type User struct {
    gorm.Model
    UserID         uint          
    Age              uint         `gorm:"-"`
}

// Age Initialize to 0 , updates to 18 now.
db.Model(u).Updates(&User{Age: 18})

// log 
u.Age = 0 before update.
u.Age = 18 after update.

In gorm V2 now , the value will not changed.

u.Age = 0 before update.
u.Age = 0 after update.

Is this behavior change a bug ?

If not , is there a writing style to get results like V1 ?

Thanks so much !
