如何在gorm中实现多模型自动迁移

type User struct {
    gorm.Model
    Name  string
    Email string
}

func main() {
    db, err := gorm.Open("mysql", "user:password@tcp(127.0.0.1:3306)/database?charset=utf8mb4&parseTime=True&loc=Local")
    if err != nil {
        panic("failed to connect database")
    }
    defer db.Close()

    // 自动迁移所有模型
    db.AutoMigrate(&User{})
}
