ORM——关系对象模型

对象关系映射(英语:Object Relational Mapping,简称ORM,或O/RM,或O/R mapping),是一种程序技术,用于实现面向对象编程语言里不同类型系统的数据之间的转换。从效果上说,它其实是创建了一个可在编程语言里使用的“虚拟对象数据库”。

laravel中的Eloquent ORM用于和数据表互动,其中每个数据库表会和一个对应的「模型」互动,想要了解请查看官方文档或自行百度。获取关联表里的属性值代码如下:

/**
* [getContactAttribute 获取卖家联系人]
*/
public function getContactAttribute()
{
return $this->hasOne('App\Http\Models\Supplier', 'SupplierId', 'SupplierId')->first()->contact;
}

以上所述是小编给大家介绍的orm获取关联表里的属性值,希望对大家有所帮助!
