Seeders are required in Laravel 10 to populate the database with initial or test data. While executing all seeders to populate the whole database is a usual strategy, there may be times when you want to execute a certain seeder separately, targeting only specific tables or data.

This article will walk you through the process of running a specific seeder in Laravel 10. We’ll look at the commands and parameters in Laravel’s Artisan CLI for running a single seeder and seeding specific data into your database.

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

Methods To Run Seeder File

When we create seeders, it will be stored inside /database/seeders folder.

DatabaseSeeder.php is the file from where we can run all seeders for application.

There are two ways by the help of which we can run a specific seeder file when we need.

By using DatabaseSeeder.php file
By using –class flag in artisan command

Using ‘DatabaseSeeder.php’ File To Seed Data

Whenever we execute the artisan command like db:seed, it runs all application’s Seeders.

$ php artisan db:seed

The above command will always call DatabaseSeeder.php to seed data or it finds the linked seeder classes from there.

<?php

namespace Database\Seeders;

// use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use Database\Seeders\ProductSeeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     */
    public function run(): void
    {
        // \App\Models\User::factory(10)->create();

        $this->call(ProductSeeder::class);

        // \App\Models\User::factory()->create([
        //     'name' => 'Test User',
        //     'email' => 'test@example.com',
        // ]);
    }
}

Linked Seeder Class

$this->call(ProductSeeder::class);

Whenever you want to run only one seeder class file, specify the linking of that class here.

Run Migration with Seeder

The given command helps to run migrations with seeder (test data) in laravel application. It calls DatabaseSeeder.php file.

$ php artisan migrate:fresh --seed

Run Seeders Forcefully

It calls DatabaseSeeder.php file while data seeding.

$ php artisan db:seed --force

Using –class flag in Artisan Command

While using db:seed command also we have a available flag by which we can run only a specific seeder class file.

The given command runs only a specified seeder class –

# Run ProductSeeder File
$ php artisan db:seed --class=ProductSeeder

# Run UserSeeder File
$ php artisan db:seed --class=UserSeeder

Run Specific Seeder Forefully

$ php artisan db:seed --class=UserSeeder --force
