Laravel: 自定义数组验证取决于之前选择的值

Question

Laravel版本：7.x

我已经使用硬编码有效 device_company_id（与所选设备相关联）测试了代码，它工作正常。

表

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 exists 验证器的自定义验证规则来验证 device 是否确实属于所选的 device_company。因为我不希望任何人打开检查工具，更改值并导致应用程序出错或类似的事情。

这是 link 我找到参考的地方 https://ericlbarnes.com/2015/04/04/laravel-array-validation/

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);

...

尽管这段代码对我有用，但我觉得这不是正确的方法。感觉有点绕过而不是正确的解决方案。如果有人找到更好的解决方案，请 post 你的答案。

希望这对某人有所帮助。谢谢:)
