laravel 查找数据 Eloquent ORM 查询

laravel mysql php

现在 有 2个 表
goods 和 products

<code> $products = Goods::where('merchant_id','=','5')->get();


 foreach($products as $p){
            print_r($p->product_id);
            $_name = Product::where('id','=',$p->product_id)->get();
            $_name = $_name[0];

}
</code>

首先 我们去 goods 表 去 查询 merchant_id = 5 的 商品;

因为 在 goods 表里面 没有 改 商品的 名字 和 更多详细的信息 ;

所以 需要 循环 goods 表里查询到的数据 通过 goods 表的 product_id 字段 去 products 查询 products 的 id 字段 所匹配的 更多信息 (name ) 等等

改怎么查询呢

我现在想到的 是 给 $products 这对象 循环添加查询到的 名字

有大神指导一下吗 (*^__^*) 嘻嘻……

<code>php</code><code>class Goods extends Model {

    public function product()
    {
        return $this->belongsTo('App\Products');
    }
}
$products = Goods::with('product')->where('merchant_id','=','5')->get();//数组里的product就是goods 表的 product_id 对应products的信息
