Laravel Backpack 表字段列（json-array）验证规则不起作用

Question

我正在使用 BackpackForLaravel，并且我的代码中有一个 table 类型字段：

$this->crud->addField([
    'label'           => 'Contact persons',
    'name'            => 'contact',
    'type'            => 'table',
    'entity_singular' => 'contact',
    'columns'         => [
        'person' => 'Person',
        'email'  => 'Email',
        'number' => 'Phone number',
        'desc'   => 'Description',
    ],
    'attributes'        => [
        'required' => true
    ],
    'max'               => 5,
    'min'               => 1,
    'wrapper'           => [
        'class' => 'form-group col-12'
    ],
    'tab' => 'Contact data',
]);

CRUD 工作正常，但是当我添加验证时，有些东西不能正常工作。

我的ClientRequest.php 班级有：

public function rules()
    {
        return [
            'cif'                            => "required|spanish_tax_number|unique:clients,cif,{$this->cif},cif",
            'name'                           => 'required|min:3|max:255',
            'address'                        => 'required|json',
            'weekly_rest'                    => 'nullable|array',
            'description'                    => 'nullable|max:255',
            'leaving_date'                   => 'nullable|date',
            'leaving_date'                   => 'nullable|date',
            'image'                          => 'nullable|image|mimes:jpeg,png',
            'contact'                        => 'required|array',
            'contact.*.person'               => 'required|email'
        ];
    }

contact 字段验证效果很好，但是当我尝试使用 contact.*.person 来验证所有名为 array 的字段 person 时，没有任何反应。

我使用函数prepareForValidation将字段json格式修改为array格式：

protected function prepareForValidation()
    {
        $this->merge([
            'contact' => json_decode($this->input('contact'))
        ]);
    }

如果我转储输入数据，我可以看到函数 prepareForValidation 运行良好，但验证没有做任何事情。

我在这里读到了数组验证：

• https://github.com/Laravel-Backpack/CRUD/issues/1582
• https://laravel.com/docs/7.x/validation#validating-arrays

我这样做，并且工作（在store/update 控制器函数中进行验证）：

• https://github.com/Laravel-Backpack/CRUD/issues/607#issuecomment-293729520

但是，我想不那么繁琐，在ClientRequest 类中编码。

我认为我做得很好，但没有工作。

我在ClientRequest 做错了什么？

我在ClientController.php的存储/更新功能中这样做：

$validate = Validator::make($request->all(), [
            'contact'                          => 'required|array',
            'contact.person'                   => 'required|string',
            "contact.*.person"                 => 'required|string',
        ]);

dd($validate->messages());

输出是：

Illuminate\Support\MessageBag {#1520 ▼
  #messages: array:2 [▼
    "contact" => array:1 [▼
      0 => "El campo contact debe ser un array."
    ]
    "contact.person" => array:1 [▼
      0 => "El campo contact.person es obligatorio."
    ]
  ]
  #format: ":message"
}

由于'contact.*.person' 丢失，某事无法正常工作。

改变

'contact' => json_decode($this->input('contact'))

开

'contact' => json_decode($this->input('contact'), true)

并保留你的旧规则
