Gorm 执行Save操作更新时，CreatedAt会被更新

Description

type BaseModel struct {
    CreatedAt time.Time 
    UpdatedAt time.Time
}
type Package struct {
    Id     int64   `gorm:"primarykey"`
    Name   string  `gorm:"type:varchar(255) comment '套餐名称';not null"`
    Money  float32 `gorm:"type:decimal(10,2) comment '套餐金额';not null"`
    Fields string  `gorm:"type:longtext comment '套餐项';not null"`
    Status uint8   `gorm:"default:1;type:tinyint(1) comment '状态: 0 下架 1 上架 2 作废';not null"`
    BaseModel
}

//  操作更新
func (m *defaultPackageModel) Update(ctx context.Context, data *Package) error {
    old, err := m.FindOne(ctx, data.Id)
    if err != nil && !errors.Is(err, ErrNotFound) {
        return err
    }
    err = m.ExecCtx(ctx, func(conn *gorm.DB) error {
        return conn.Save(data).Error
    }, m.getCacheKeys(old)...)
    return err
}

    // 更新数据库
    err = l.svcCtx.PackageModel.Update(l.ctx, &model.Package{
        Id:     in.Id,
        Name:   in.Name,
        Money:  in.Money,
        Fields: in.Fields,
        Status: uint8(in.Status),
    })

补充描述

经过测试如果给CreatedAt 增加 gorm:"<-:create" 则是正常的

Check the created_at field, maybe ON UPDATE CURRENT_TIMESTAMP is assigned.
