Iseed Laravel Package
orangehill/iseed
Generate Laravel database seeders from existing table data. iSeed adds an artisan command to export one or many tables (or all tables) into seeder classes, with optional class name prefix/suffix to avoid overwriting. Supports Laravel 8–13 (PHP 8+).

Frequently asked questions about Iseed
- How do I generate seeders for all tables in my Laravel database?
- Run `php artisan iseed` without arguments. The package automatically detects all tables and generates a seeder class for each. For Laravel 8+, no additional configuration is needed due to auto-discovery.
- Can I use iseed to create seeders for specific tables only?
- Yes. Use CSV notation to specify tables: `php artisan iseed users,products`. This generates separate seeders for each table while skipping others. Combine with `--classnameprefix` to avoid conflicts.
- Does orangehill/iseed support Laravel 13 and PHP 8.1+?
- Yes, the package officially supports Laravel 8–13 and PHP 8.0+. For Laravel 13, use the latest stable version (no extra steps required). Check the [GitHub repo](https://github.com/orangehill/iseed) for version-specific notes.
- How do I handle sensitive data (e.g., passwords, emails) in generated seeders?
- Avoid seeding sensitive data directly. Use `--where` to filter production data (e.g., `php artisan iseed users --where='id < 10'`) or pre-process seeders with scripts (e.g., `str_replace` for emails). Never commit real PII to version control.
- Will iseed work with PostgreSQL or MySQL foreign keys?
- Yes, but with caveats. For PostgreSQL, use `--reset-sequences` to handle auto-increment fields. MySQL foreign keys are preserved, but test seeders thoroughly. Large tables may require `--chunksize` to avoid constraint violations during bulk inserts.
- Can I integrate iseed into a CI/CD pipeline for automated seeder generation?
- Absolutely. Trigger `php artisan iseed` in your pipeline (e.g., post-migration) to generate seeders from a staging DB. Use `--database=staging` to target a specific connection. Pair with Laravel’s `php artisan migrate:fresh --seed` for full workflows.
- How do I customize the generated seeder class names or file structure?
- Use `--classnameprefix` or `--classnamesuffix` to modify names (e.g., `php artisan iseed users --classnameprefix=Test_`). For deeper customization, override the default stub templates in `resources/views/vendor/iseed` or publish them with `php artisan vendor:publish --tag=iseed.stubs`.
- What’s the best way to test seeders generated by iseed?
- Use PestPHP or PHPUnit to verify seeders. Generate seeders from a controlled DB (e.g., `php artisan iseed --database=test`), then assert data integrity with `DatabaseMigrations` or snapshot testing. For large datasets, test with `--max=100` first.
- Does iseed support non-default database connections (e.g., MySQL replica)?
- Yes. Specify the connection with `--database=connection_name` (e.g., `php artisan iseed --database=mysql_replica`). This works for read replicas, PostgreSQL, or any connection defined in `config/database.php`. Test connection-specific quirks (e.g., timezones) manually.
- Are there alternatives to orangehill/iseed for Laravel seeder generation?
- For Laravel, alternatives include `laravel-shift/database-seeder-generator` (similar CLI tool) or manual `DB::table()->get()` in custom seeders. For non-Laravel PHP, consider `doctrine/dbal` or custom scripts. However, iseed is the most Laravel-native option with built-in Artisan integration and stub templating.
