Creating a Seeder in Laravel 8

In this post, I will share an example of how to create a Laravel 9 seeder. Seeder is important to initialize our default data to our database.


Here is an example:


Step 1: Create Laravel Seeder

Let's create a Laravel seeder for our posts table. Run the following command:

php artisan make:seeder CreatePostsSeeder


Step 2: Insert Data

Once our Laravel seeder is generated kindly to the database/seeders directory. Open the CreatePostsSeeder.php and you will see the following code:


namespace Database\Seeders;

use App\Models\Post;
use Illuminate\Database\Seeder;

class CreatePostsSeeder extends Seeder
     * Run the database seeds.
     * @return void
    public function run()
            'title' => 'Post 1',
            'description' => 'Description for post 1',
            'body' => 'Body for post 1'

            'title' => 'Post 2',
            'description' => 'Description for post 2',
            'body' => 'Body for post 2'

            'title' => 'Post 3',
            'description' => 'Description for post 3',
            'body' => 'Body for post 3'

            'title' => 'Post 4',
            'description' => 'Description for post 4',
            'body' => 'Body for post 4'

            'title' => 'Post 5',
            'description' => 'Description for post 5',
            'body' => 'Body for post 5'


As you can see in the run() method we added inserting post data.


Now let's save the data by running the following commands below:

php artisan db:seed


or in a specific command for a seeder class:

php artisan db:seed --class=CreatePostsSeeder


Once done it will save the seeder data.


You can also rollback the rerun the migrations with the command below:

php artisan migrate:refresh --seed


The migrate:refresh --seed is a shortcut of the following commands below:

php artisan migrate:reset     # rollback all migrations
php artisan migrate           # run migrations
php artisan db:seed           # run seeders


I hope it helps. Thanks for reading :)
