Laravel：自定义数组验证取决于先前选择的值

Question

Laravel版本：7.x

我已经使用硬编码的有效device_company_id（与所选设备相关联）测试了该代码，并且工作正常。

表格

device_companies
|- id
|- company_id
|- title
|- ...

devices
|- id
|- device_company_id
|- ...

请求数据

Array
(
    ...

    [devices] => Array
        (
            [0] => Array
                (
                    [device_company_id] => 1
                    [device_id] => 2
                    [device_inventory_id] => null
                    [amount] => 
                    [refundable] => 
                    [description] => 
                )

        )
)

规则：

...

$rules = array_merge($rules, [
    'devices' => [
        'required', 
        'array'
    ],
    'devices.*.device_company_id' => [
        'required', 
        'integer', 
        'exists:device_companies,id,company_id,' . auth()->user()->id
    ],
    'devices.*.device_id' => [
        'required', 
        'integer', 
        'exists:devices,id,device_company_id,devices.*.device_company_id'
    ],
]);

...

我需要一个用于exists验证程序的自定义验证规则，以验证device是否实际上属于所选的device_company。因为我不希望任何人打开检查工具，所以请更改值并导致应用程序出现错误或类似情况。

这里是我找到参考文献https://ericlbarnes.com/2015/04/04/laravel-array-validation/的链接>

我的代码：

...

$rules = [
    ...other rules
];

$newRules = [
    'devices' => [
        'required', 
        'array'
    ],
    'devices.*.device_company_id' => [
        'required', 
        'integer', 
        'exists:device_companies,id,company_id,' . auth()->user()->id
    ],
];

foreach($data['devices'] as $key => $array)
{
    $newRules["devices.{$key}.device_id"] = [
        'required',
        'integer',
        "exists:devices,id,device_company_id,{$array["device_company_id"]}",
    ];
}

$rules = array_merge($rules, $newRules);
