复合主键

Preview

通过将多个字段设为主键,以创建复合主键,例如:

type Product struct {
  ID           string `gorm:"primaryKey"`
  LanguageCode string `gorm:"primaryKey"`
  Code         string
  Name         string
}

**注意:**默认情况下,整型 PrioritizedPrimaryField 启用了 AutoIncrement,要禁用它,您需要为整型字段关闭 autoIncrement

type Product struct {
  CategoryID uint64 `gorm:"primaryKey;autoIncrement:false"`
  TypeID     uint64 `gorm:"primaryKey;autoIncrement:false"`
}
