# Add Export ## When to use When a new entity must be exportable to CSV/XLSX. Exports run asynchronously through `App\Jobs\ProcessExport` on the `heavy` queue and are tracked with `App\Models\DataProcessingJob`. See `AGENTS.md` §7.14. **Exports read from the application database — never query external services from an exporter.** ## Steps 1. **Write the exporter** in `app/Exports/{Entity}Export.php` implementing `App\Exports\Contracts\Exportable` (and `WithMapping` when rows need shaping). It receives a `filters` array from the queued job. ```php use App\Exports\Contracts\Exportable; use Illuminate\Support\Collection; use Maatwebsite\Excel\Concerns\WithMapping; /** @implements WithMapping<Entry> */ class EntryExport implements Exportable, WithMapping { /** @param array<string, mixed> $filters */ public function __construct(private array $filters = []) {} /** @return Collection<int, Entry> */ public function collection(): Collection { // Query PostgreSQL only. } /** @param Entry $row */ public function map($row): array { return []; } /** @return array<int, string> */ public function headings(): array { return []; } } ``` 2. **Register the entity** on `App\Enums\DataEntity`: add a case and a `makeExporter()` arm returning the exporter instance. 3. **Expose it to the UI** — `ExportController` (`StoreExportRequest` validates with `Rule::enum(DataEntity::class)`) accepts `entity_type` plus `format` (`csv`/`xlsx`) as soon as the enum case exists. 4. **Test it** — run the job with `Storage::fake('local')` and assert the file and database state. `tests/Feature/Export/ProcessExportJobTest.php` is the template. ## Notes - Files are written to the disk in `config/exports.php` and downloaded through `ExportController@download`. - Completed jobs and their files are pruned by the scheduled `data-processing:cleanup-completed` command. - Use `tests/Mock/ExportMockData` for request payloads in tests. ## Completion checks - [ ] Exporter implements `Exportable` and reads only PostgreSQL. - [ ] `DataEntity` case + `makeExporter()` arm added. - [ ] Job test asserts the generated file and DB state. - [ ] `composer check` passes.
