如何在 maatwebsite/excel 中从 2.x 升级到 3.x？

Question

我将我的应用程序迁移到 laravel 5.7。在 composer.json 中安装软件包时，我从“maatwebsite/excel:~2.1.0”升级到“maatwebsite/excel”:“^3.1”。所以现在我的导出功能不再工作了。我尝试在https://docs.laravel-excel.com/3.1 中进行升级，但对我不起作用。这是以前在旧版本中工作的旧代码：

$claim = Claim::all();
$count = Claim::count();
$name = 'Liste réclamations '.date('d-m-Y H-i');
    Excel::create($name, function($excel) use($claim, $count) {

        $excel->sheet('Sheetname', function($sheet) use($claim, $count) {

            $i = 2;
            $rows = $count;
            $rows++;

            $sheet->setHeight(1, 25);
            $sheet->setAutoSize(true);
            $sheet->setBorder('A1:AH'.$rows, 'thin');

            $sheet->row(1, array(

                'Utilisateur',
                'Référence',
                'Infraction',
                'Groupe oiseaux',
                "Type de braconnage",
                "Type de l'espèce",

我已经重新创建了您的项目示例来完成这项工作： 完全按照我的步骤执行：

1. 安装包：

composer require maatwebsite/excel

1. 现在运行以下命令：

php artisan make:export ClaimsExport --model=Claim

1. 这将创建 app/Exports/ClaimsExport.php。粘贴以下代码：

<?php

namespace App\Exports;

use App\Claim;
use Maatwebsite\Excel\Events\AfterSheet;
use PhpOffice\PhpSpreadsheet\Style\Fill;
use Maatwebsite\Excel\Concerns\WithEvents;
use PhpOffice\PhpSpreadsheet\Style\Border;
use Maatwebsite\Excel\Concerns\WithMapping;
use Maatwebsite\Excel\Concerns\WithHeadings;
use Maatwebsite\Excel\Concerns\ShouldAutoSize;
use Maatwebsite\Excel\Concerns\FromCollection;

class ClaimsExport implements FromCollection, WithHeadings, ShouldAutoSize, WithEvents, WithMapping
{
    //
    public function headings(): array
    {
        return [
            'Utilisateur',
            'Référence',
            'Infraction',
            'Groupe oiseaux',
            "Type de braconnage",
            "Type de l'espèce",
            "Nom de l'espèce",
            "Autre info de l'espèce",
            "Description de l'oiseau",
            "Le nombre d'oiseau",
            "Le nombre d'oiseaux mis en vente",

            $claim->time_infraction,
            $claim->description_infraction,
            $claim->etat,
            $claim->created_at,
        ];
    }

    //

                        'color' => ['argb' => 'FFFFFFFF'],
                    ],
                    'borders' => [

                            'borderStyle' => Border::BORDER_THIN,
                        ],

                $event->sheet->getDelegate()->getStyle('A1:AG1')->applyFromArray($styleArray);
            },
        ];
    }
}

• 你会在那里找到 TODO。尝试自己实现。我不知道 Claimtypelink 和 Claimcontactlink 有什么作用。

  4. 现在在控制器内部添加以下方法：

public function export()
{
    $name = 'Liste réclamations ' . date('d-m-Y H-i') . '.xlsx';

    return Excel::download(new ClaimsExport, $name);
}

并将其添加到该文件的顶部：

use App\Exports\ClaimsExport;
use Maatwebsite\Excel\Facades\Excel;

5. 内部路线添加：

Route::get('claims/export', 'ClaimController@export')->name('export');

你可以走了。
