如果我正在尋找有信用卡號碼的人，CreditCardNumber這是正確的方法嗎？type Person struct {    gorm.Model    Name            string    CreditCard CreditCard }type CreditCard struct {    gorm.Model    PersonID       *uint    Number string}database.dbClient.   Preload("CreditCard").   Where("credit_card.number = ?", CreditCardNumber).   Joins("left join credit_cards on person.id = credit_card.person_id AND credit_card.deleted_at is NULL").   First(&Person)
