Laravel（9）和PHP（8.1）中的项目。
我想导入一个excel文件并使用maatwebsite/excel（3.1）包。
我可以导入一个文件，并将该文件保存到模型中，如下所示：
导入类：

class BankTransfersHistoryImport implements ToModel, WithHeadingRow, WithValidation, WithBatchInserts
{
    use Importable;

    private $rows;

    public function __construct()
    {
        $this->rows = collect();
    }

/**
 * @param array $row
 *
 * @return \Illuminate\Database\Eloquent\Model|null
 */
    public function model(array $row)
    {
        $bankTransferHistory = new BankTransfersHistory([    
            'loanId' => $row['loanId'],
            'actionDate' => transformDate($row['actionDate']),
            'worth' => $row['worth'],
            .
            .
        ]);

        $this->rows->push($bankTransferHistory);
        return $bankTransferHistory;
    }

    /**
     * Returns Imported Data
     *
     * @return \Illuminate\Support\Collection
     */
    public function getImportedData(): \Illuminate\Support\Collection
    {
        return $this->rows;
    }

    public function headingRow(): int
    {
        return 2;
    }

    public function rules(): array
    {
        return [ 
            '*.loanId' => ['required', 'numeric'],
            ... some roles ...
        ];
    }
}

控制器：

public function store(Request $request)
    {
        $request->validate([
            'file' => 'required|mimes:xls,xlsx',
        ]);

        $file = $request->file('file');

        $import = new BankTransfersHistoryImport;

        try {
            // date validation
            $collection = $import->toCollection($file);
            ... some validation about the date ...

            $import->import($file);
            $getImportedData = import->getImportedData();
            ... check and update rows ...

            return [
                "message" => some message,
                "data" => [
                    some data
                ],
            ];

        } catch (\Maatwebsite\Excel\Validators\ValidationException$e) {
            $failures = $e->failures();

            foreach ($failures as $failure) {
                $failure->row(); // row that went wrong
                $failure->attribute(); // either heading key (if using heading row concern) or column index
                $failure->errors(); // Actual error messages from Laravel validator
                $failure->values(); // The values of the row that has failed.
            }
            return $failures;
      }

我的问题是：

如果我在保存数据后可以得到文件的响应，那么就会给予带有保存的行ID的数据。
在某些情况下，我将不得不更新行。这就是为什么我想获得ID。
现在，在检查和更新行部分，我按loanId + actionDate更新行。
就像这样：
代码：$getImportedData = import->getImportedData();
数据将类似于：

[
    {
        "id": 1,
        "loanId": 21001,
        "actionDate": "2020-01-02T00:00:00.000000Z",
        "worth": 2997.09,
        "offerId": 1,
    },
    {
        "id": 2,
        "loanId": 21002,
        "actionDate": "2020-01-02T00:00:00.000000Z",
        "worth": 3000,
        "offerId": 10,
    },
]
