README

Laravel Seeder Generator is a powerful package that allows you to generate seeders from existing database tables with hardcoded data. This is extremely useful for creating backups or replicating database states across different environments.

🚀 Features

✅ Automatically generates seeders from database tables
✅ Handles large datasets with chunking
✅ Option to overwrite existing seeders
✅ Efficient memory handling using Laravel's cursor
✅ Easy installation and simple usage
✅ Supports Laravel 9+

📦 Installation

You can install the package via Composer:

composer require zainularfeen/laravel-seeder-generator --dev

The package will be auto-discovered in Laravel. If not, you can manually register the Service Provider:

// config/app.php
'providers' => [
    Zainularfeen\SeederGenerator\SeederGeneratorServiceProvider::class,
];

⚡ Usage

Generate Seeders for All Tables

Run the following command to generate seeders for all database tables:

php -d memory_limit=-1 artisan generate:seeders

Custom Chunk Size

If your database has a large number of records, you can control how many rows are processed at a time using the --chunk option:

php -d memory_limit=-1 artisan generate:seeders --chunk=500

Force Overwrite Existing Seeders

By default, if a seeder file already exists, it will not be overwritten. Use --force to regenerate all seeders:

php -d memory_limit=-1 artisan generate:seeders --force

Combine Options

You can combine options like this:

php -d memory_limit=-1 artisan generate:seeders --chunk=1000 --force

🛠️ How It Works

The command fetches all tables from the database.
It skips system tables like migrations and telescope_entries.
It reads all records using Laravel's cursor() to avoid memory issues.
Data is hardcoded into Laravel seeder files inside the database/seeders directory.
You can run php artisan db:seed --class=YourTableSeeder to seed your database.

📌 Example Output

After running the command, it generates seeder files inside database/seeders:

<?php
namespace Database\Seeders;

use Illuminate\Database\Seeder;
use Illuminate\Support\Facades\DB;

class UsersSeeder extends Seeder
{
    public function run()
    {
        DB::table('users')->insert([
            ['id' => 1, 'name' => 'John Doe', 'email' => 'john@example.com', 'created_at' => now(), 'updated_at' => now()],
            ['id' => 2, 'name' => 'Jane Smith', 'email' => 'jane@example.com', 'created_at' => now(), 'updated_at' => now()],
        ]);
    }
}

🔄 Running the Generated Seeders

Once the seeders are generated, you can use Laravel's built-in seeding commands:

php artisan db:seed --class=UsersSeeder

To seed all generated seeders at once:

php artisan db:seed

🔧 Troubleshooting

Seeder File Already Exists

❌ "Seeder already exists for users. Use --force to overwrite."

Solution: Use the --force flag:

php artisan generate:seeders --force

Out of Memory Issues

❌ "PHP Fatal error: Allowed memory size exhausted"

Solution: Run the command with unlimited memory:

php -d memory_limit=-1 artisan generate:seeders
