Customizing Filament Export Action

Hello everyone, I would need some help with an issue I'm facing regarding the export action in Filament. Currently, I have a resource where I allow exporting using Filament's standard export action. After several attempts, I managed to get database notifications working as well, all very nice. Unfortunately, I can't figure out how to override/modify the link for downloading the file. I have a customized setup for the application's storage (it's not located internally but at a specific path on the Linux machine hosting my app). Using route:list, I noticed that there's a Filament route 'filament/exports/{id}/download' that is definitely used for returning the file to download, but I can't seem to access it or override it. Could you help me in some way? I could solve it in different ways; I just need to override the link with my custom one pointing to a route I created (already existing and working for other downloads). Thank you very much!

Solution:

actually linux permissions on the folder...

As you can see the notification is working perfectly fine!

You should use the storage disk: https://filamentphp.com/docs/3.x/actions/prebuilt-actions/export#customizing-the-storage-disk Once the disk is set, then you should be able to set the url method on the disk too.

Thanks for the fast reply. This is my code (i added now the disk method, but actually it is the default one).

ExportAction::make()
                    ->label('Export Report Scarico')
                    ->exporter(KiidMailReportExporter::class)
                    ->fileName(fn (): string => "kiid-report-" . Carbon::now()->toDateString())
                    ->maxRows(50000)
                    ->fileDisk('download')
                    ->formats([
                        ExportFormat::Xlsx,
                    ]),

ExportAction::make()
                    ->label('Export Report Scarico')
                    ->exporter(KiidMailReportExporter::class)
                    ->fileName(fn (): string => "kiid-report-" . Carbon::now()->toDateString())
                    ->maxRows(50000)
                    ->fileDisk('download')
                    ->formats([
                        ExportFormat::Xlsx,
                    ]),

I can't understand how and where should i override the url u mentioned? ty

toeknee•9mo ago

you set fileDisk = download. So download is the disk defined in filesystem.php

SirAlyonOP•9mo ago

Yes of course 🙂

'download' => [
            'driver' => 'local',
            'root' => '/dati',
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
            'throw' => false,
            'permissions' => [
                'file' => 0775,
                'dir' => 0775,
            ]

'download' => [
            'driver' => 'local',
            'root' => '/dati',
            'url' => env('APP_URL').'/storage',
            'visibility' => 'public',
            'throw' => false,
            'permissions' => [
                'file' => 0775,
                'dir' => 0775,
            ]

is this the url method i have to modify?

toeknee•9mo ago

I believe so

SirAlyonOP•9mo ago

mmm it doesn't change the notification link..

SirAlyonOP•9mo ago

toeknee•9mo ago

are you getting a 419 by any chance?

SirAlyonOP•9mo ago

'download' => [
            'driver' => 'local',
            'root' => '/dati',
            'url' => '/dati',
            'visibility' => 'public',
            'throw' => false,
            'permissions' => [
                'file' => 0775,
                'dir' => 0775,
            ]
        ],

'download' => [
            'driver' => 'local',
            'root' => '/dati',
            'url' => '/dati',
            'visibility' => 'public',
            'throw' => false,
            'permissions' => [
                'file' => 0775,
                'dir' => 0775,
            ]
        ],

If you mean an error code 419, nope.

toeknee•9mo ago

So what are you trying to change?

SirAlyonOP•9mo ago

This download link:

toeknee•9mo ago

But why? The download link is a route for filament to fetch the file and download it. It's not a direct link.

SirAlyonOP•9mo ago

I just want it working fine... and it isn't

toeknee•9mo ago

So the file isn't downloading?

SirAlyonOP•9mo ago

nop!

toeknee•9mo ago

What is the error?

SirAlyonOP•9mo ago

toeknee•9mo ago

inspect the network what's the error. I have a feeling it is 419

SirAlyonOP•9mo ago

toeknee•9mo ago

500, so inspect your logs to what is causing a 500

SirAlyonOP•9mo ago

Also, under my storage folder filament is saving the file under /filament_exports/{DINAMIC ID}/file.xlsx

toeknee•9mo ago

That's correct

SirAlyonOP•9mo ago

This route is trying to download from, filament/exports, no way its gona work(?)

toeknee•9mo ago

Read the route. It's a download function of a file. not a direct link.

Route::get('/filament/exports/{export}/download', DownloadExport::class)
    ->name('filament.exports.download')
    ->middleware(['web', 'auth']);

Route::get('/filament/exports/{export}/download', DownloadExport::class)
    ->name('filament.exports.download')
    ->middleware(['web', 'auth']);

which runs

    public function __invoke(Request $request, Export $export): StreamedResponse
    {
        if (filled(Gate::getPolicyFor($export::class))) {
            authorize('view', $export);
        } else {
            abort_unless($export->user()->is(auth()->user()), 403);
        }

        $format = ExportFormat::tryFrom($request->query('format'));

        abort_unless($format !== null, 404);

        return $format->getDownloader()($export);
    }

    public function __invoke(Request $request, Export $export): StreamedResponse
    {
        if (filled(Gate::getPolicyFor($export::class))) {
            authorize('view', $export);
        } else {
            abort_unless($export->user()->is(auth()->user()), 403);
        }

        $format = ExportFormat::tryFrom($request->query('format'));

        abort_unless($format !== null, 404);

        return $format->getDownloader()($export);
    }

Solution

SirAlyon•9mo ago

actually linux permissions on the folder...

toeknee•9mo ago

Well done

SirAlyonOP•9mo ago

to you! Thank you very much

khairulazmi_•7mo ago

how you change the permission ? I want to have when new folder created it should be use www-data

toeknee•7mo ago

You don't you should setup your server correctly since that's handled by php-fpm.

khairulazmi_•7mo ago

Yeah . Apparently I set my supervisor wrong .
