在 Laravel 关系对象上将字符串转换为整数

Question

我有一个数组集合，其中包含 qty 作为字符串我想要的是删除一个 $ 符号并将字符串设为整数

"collection": [
        {
            "id": 983,
            "controlNumber": "4498818",
            "ItemNumber": "PS2W12077",
            "shipment": {
                "id": 27,
                "Item": "PS2W12077",
                "ColorCode": "GRPFR",
                "qty": ",638"
            }
        },
        {
            "id": 982,
            "controlNumber": "4498818",
            "ItemNumber": "PS2W12077",
            "shipment": {
                "id": 27,
                "Item": "PS2W12077",
                "ColorCode": "GRPFR",
                "qty": ",638"
            }
        },
        {
            "id": 981,
            "controlNumber": "4498818",
            "ItemNumber": "PS2W12077",
            "shipment": {
                "id": 27,
                "Item": "PS2W12077",
                "ColorCode": "GRPFR",
                "qty": ",638"
            }
        },
        {
            "id": 980,
            "controlNumber": "4498818",
            "ItemNumber": "PS2W12077",
            "shipment": {
                "id": 27,
                "Item": "PS2W12077",
                "ColorCode": "GRPFR",
                "qty": ",638"
            }
        }
]

我在模型上的关系如下

    public function Openorder()
    {
        $object = $this->hasOneThrough(OpenorderImportTemp::class, 'ItemNumber',  'Item');
        return $object;
    }

然后在控制器上抓取如下

$openorder_data = OpenorderImportTemp::
        select('id', 'controlNumber', 'ItemNumber', )
            ->with('shipment:id,Item,ColorCode,qty')
            // ->groupBy('controlNumber')
            ->orderby('id', 'desc')
            ->where('ControlNumber', '!=', '0')
            ->get();

根据需要将字符串更改为整数的任何可能性。我试过的是下面

$openorder_data = OpenorderImportTemp::
        select('id', 'controlNumber', 'ItemNumber', DB::raw("SUM(shipment.qty) as qtysum") )
            ->with('shipment:id,Item,ColorCode,qty')
            // ->groupBy('controlNumber')
            ->orderby('id', 'desc')
            ->where('ControlNumber', '!=', '0')
            ->get();

Answer 1

protected $casts = [
        'qty' => 'integer',
    ];

模型解决了我的问题。将字符串更改为整数
