Inside this article we will see the concept i.e How To Use Laravel 10 Seeder for Database Seeding Tutorial. Article contains the classified information i.e Best practices for database seeding with Laravel 10.

In Laravel 10, seeders are a powerful tool that can be used to populate your database with test data. A seeder is essentially a class that defines the data to be inserted into the database, and Laravel provides an easy-to-use Seeder class that can be extended to create your own seeders.

This tutorial will guide you through the process of using Laravel 10 seeders to populate your database with test data.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

$ composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

$ php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

How To Create Migration in Laravel?

We will create a events table using migration and then we seed test data inside it.

Open project into terminal and run this command to create a migration file.

$ php artisan make:migration create_events_table

It will create 2023_03_17_031027_create_events_table.php file inside /database/migrations folder. Open migration file and write this following code into it.

The code is all about for the schema of events table.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('events', function (Blueprint $table) {
            $table->id();
            $table->string('title', 50);
            $table->date('start');
            $table->date('end');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('events');
    }
};

Run Migration

Back to terminal and run this command.

$ php artisan migrate

It will create events table inside database.

How To Create Data Seeder in Laravel?

Next,

Copy this command and run into terminal to create a data seeder for events table.

$ php artisan make:seeder FakeEventSeeder

It will create a file FakeEventSeeder.php inside /database/seeders folder.

Open file and write this following code into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\Event;

class FakeEventSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $data = [
            ['title' => 'Fake Event-1', 'start' => '2023-03-11', 'end' => '2023-03-12'],
            ['title' => 'Fake Event-2', 'start' => '2023-03-15', 'end' => '2023-03-17'],
            ['title' => 'Fake Event-3', 'start' => '2023-03-25', 'end' => '2023-03-27'],
            ['title' => 'Fake Event-4', 'start' => '2023-03-20', 'end' => '2023-03-23'],
        ];
        foreach ($data as $key => $value) {
          
            Event::create($value);
        }
    }
}

How To Run Laravel Data Seeder?

We have multiple options available to execute a seeder file to database.

We will discuss about these two –

Using DatabaseSeeder
Without Using DatabaseSeeder

Using DatabaseSeeder

We load seeder class into DatabaseSeeder.php which should be inside /database/seeders folder.

Open file and load FakeEventSeeder.php into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Database\Seeders\FakeEventSeeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call(FakeEventSeeder::class); // Run Seeder Class
    }
}

Run Seeder

Back to terminal and run this command.

$ php artisan db:seed

Without Using DatabaseSeeder

Here, we run FakeEventSeeder.php file directly instead of loading it to DatabaseSeeder.php file.

$ php artisan db:seed --class=FakeEventSeeder

We specify the class flag with seeder class name. It runs specified seeder class name.
