Question

我有一个终点，当前的响应如下所示，当我们使用groupBy（）查询时，它只返回一行，但是如何获得一个带有隐藏分组值的嵌套json。

//controller

    public function products()
    {
        $get_products = Product::groupBy('name')
                               ->get();

        $data = [
            'data' => $get_products
        ];

        return Response::json(
            $data_with_status = array_merge($this->respondSuccess('query successfull'), $data)
        );
    }

//json response   

    {
        "status_code": 200,
        "status_message": "query successfull",
        "data": [
            {
                "id": 1,
                "name": "onion",
                "proportion": "500 gm",
                "mrp": "25",
                "price": "22",
                "status": "1"
            }
        ]
    }

预期结果如下，是否有查询来实现此目的，

{
    "status_code": 200,
    "status_message": "query successfull",
    "data": [
        {
            "id": 1,
            "name": "onion",
            "proportion": {
                "0": "500 gm",
                "1":  "1 kg",
            }
            "mrp": "25",
            "price": "22",
            "status": "1"
        },
        {
            "id": 2,
            "name": "tomato",
            "proportion": "500 gm"
            "mrp": "20",
            "price": "15",
            "status": "1"
        }
    ]
}

数据库架构如下

Schema::create('products', function (Blueprint $table) {
    $table->increments('id');
    $table->string('name');
    $table->string('proportion');
    $table->string('mrp');
    $table->string('price');
    $table->enum('status', ['available','unavailable']);
    $table->timestamps();
    $table->softDeletes();
});

要从产品表分组的样本数据

id  name      proportion  mrp  price  status 
1   onion      500 gm     25    22     1
2   onion      1 kg       50    44     1
3   tomato     500 gm     20    15     1

如果产品名称相同，则表示如果产品具有多个比例，我想对产品进行分组并将比例合并到json中，如上面预期的json结果所示。

谢谢

使用group_cancat() -

$get_products = Product::select('id','name','mrp','price','status',DB::raw('group_concat(proportion)'))
               ->groupBy('name')->get();

Laravel：groupBy嵌套json
