Laravel：在更新操作时，为关联阵列输入请求添加唯一的验证规则

我正在执行更新操作，并具有下面的输入请求：

array:1 [
  "buildings" => array:3 [
    0 => array:4 [
      "item_id" => 6
      "florida_number" => "1006"
      "serial_number" => "1002"
      "building_id" => 6
    ]
    1 => array:4 [
      "item_id" => 7
      "florida_number" => "1007"
      "serial_number" => "1002"
      "building_id" => 7
    ],
    .....
    .....
  ]
]

现在我想在 serial_number 字段上应用唯一的验证规则，该规则存储在 项目< /strong> 数据库中的表。
我需要照顾的是在检查唯一性时忽略当前项目ID。

I am doing update operation and have an input request like below:

array:1 [
  "buildings" => array:3 [
    0 => array:4 [
      "item_id" => 6
      "florida_number" => "1006"
      "serial_number" => "1002"
      "building_id" => 6
    ]
    1 => array:4 [
      "item_id" => 7
      "florida_number" => "1007"
      "serial_number" => "1002"
      "building_id" => 7
    ],
    .....
    .....
  ]
]

Now I want to apply unique validation rule on serial_number field which is stored in items table in database.
The thing I need to take care of here is to ignore the current item id while checking uniqueness.

最简单的解决方案是将以下规则添加到您的表格请求中：

return [
            'buildings' => 'array',
            'buildings.*' => Rule::forEach(function ($value, $attribute) {
                return [
                    'serial_number' => 'unique:items,serial_number,'. $value['item_id']
                ];
            })
      ];

The easiest solution is to add a rule like below to your form request:

return [
            'buildings' => 'array',
            'buildings.*' => Rule::forEach(function ($value, $attribute) {
                return [
                    'serial_number' => 'unique:items,serial_number,'. $value['item_id']
                ];
            })
      ];
