Laravel Excel 使用 Maatwebsite Excel 包从视图导入附加列

Question

我正在尝试将数据从 Excel 文件导入 MySQL。我的 table 有 2 个外键 project_id 和 site_id 导入时我从视图的下拉列表中选择这两个字段。有什么方法可以将这两个字段映射到我的导入 collection？请注意，导入文件中不存在这 2 个字段（出于完整性原因），但它们确实存在于 table.

Collection

namespace App\Imports;

use App\Proposal;
use Maatwebsite\Excel\Concerns\ToModel;
use Maatwebsite\Excel\Concerns\WithHeadingRow;

class ProposalsImport implements ToModel, WithHeadingRow
{
    public function model(array $row)
    {
        return new Proposal([
            'building'  => $row['building'],
            'floor' => $row['floor'],
            'area'    => $row['area'],
            'room'    => $row['room'],
            'luminaire'    => $row['luminaire'],
            'actual_qty'    => $row['actual_qty'],
            'installed_qty'    => $row['installed_qty'],
        ]);
    }
}

控制器

public function import() 
{
    Excel::import(new ProposalsImport, 'proposals.xlsx');
}

覆盖导入控制器的构造方法，发送你需要的所有参数，像这样：

class ProposalsImport implements ToModel, WithHeadingRow
{
    protected $project_id;
    protected $site_id;

    public function __construct($project_id, $site_id)
    {
        $this->project_id = $project_id;
        $this->site_id = $site_id;
    }

    public function model(array $row)
    {
        return new Proposal([
            'building'   => $row['building'],
            'project_id' => $this->project_id,
            'site_id'    => $this->site_id
        ]);
    }
}

然后，像这样从您的控制器中调用它：

public function import(Request $request) 
{
    Excel::import(new ProposalsImport($request->project_id, $request->site_id), 'proposals.xlsx');
}
