使用自定义参数导出数据 Laravel Excel

Question

我目前使用的是https://laravel-excel.com/的3.1版我想查询数据并将它们下载到excel文件中，但它总是返回一个空白表。

我的路线：

Route::get('/reports/excel', 'ReportController@excel');

我的 ReportsExport 控制器：

use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;


class ReportsExport implements FromView, WithEvents, ShouldAutoSize
{
    use Exportable;

    private $from, $to;

    public function __construct(String $from, String $to) {

        $this->from = $from;
        $this->to = $to;
    }

    public function view(): View
    {
        return view('reports.sample', [
            'reports' => Report::whereBetween('created_at', [$this->from, $this->to])->get()
        ]);
    }

下载控制器

    public function excel(Request $request) {
    $from = Carbon::parse($request->get('from'));
    $to = Carbon::parse($request->get('to'));

    return Excel::download(new ReportsExport($from, $to), 'reports.xlsx');
}

你能告诉我我在这里缺少什么吗？任何帮助，将不胜感激。谢谢！

我已经成功了。这是我所做的：

Exports.php

    class ReportsExport implements FromView, WithEvents, ShouldAutoSize
{
    use Exportable;

    protected $from, $to;

    public function __construct(String $from, String $to) {

        $this->from = $from;
        $this->to = $to;
    }

    public function view(): View
    {
        return view('reports.sample', [
            'reports' => User::find(Auth::user()->id)->reports()
                   ->whereDate('created_at', '>=', $this->from)
                   ->whereDate('created_at', '<=', $this->to)
                   ->get(),


        ]);
    }

我的控制器

    public function excel(Request $request) {
    $from = Carbon::parse($request->get('from'));
    $to = Carbon::parse($request->get('to'));

    return Excel::download(new ReportsExport($from, $to), 'reports.xlsx');
}
