In this post, I will share an example of how to create a Laravel 8 seeder. Seeder is important to initialize our default data to our database.

Here is the 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
Enter fullscreen mode Exit fullscreen mode

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:

<?php namespace Database\Seeders; use App\Models\Post; use Illuminate\Database\Seeder; class CreatePostsSeeder extends Seeder { /** * Run the database seeds. * * @return void */ public function run() { Post::create([ 'title' => 'Post 1', 'description' => 'Description for post 1', 'body' => 'Body for post 1' ]); Post::create([ 'title' => 'Post 2', 'description' => 'Description for post 2', 'body' => 'Body for post 2' ]); Post::create([ 'title' => 'Post 3', 'description' => 'Description for post 3', 'body' => 'Body for post 3' ]); Post::create([ 'title' => 'Post 4', 'description' => 'Description for post 4', 'body' => 'Body for post 4' ]); Post::create([ 'title' => 'Post 5', 'description' => 'Description for post 5', 'body' => 'Body for post 5' ]); } }
Enter fullscreen mode Exit fullscreen mode

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

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

php artisan db:seed
Enter fullscreen mode Exit fullscreen mode

or in a specific command for a seeder class:

php artisan db:seed --class=CreatePostsSeeder
Enter fullscreen mode Exit fullscreen mode

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
Enter fullscreen mode Exit fullscreen mode

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
Enter fullscreen mode Exit fullscreen mode

I hope this tutorial can help you. Kindly visit here https://codeanddeploy.com/blog/laravel/creating-a-seeder-in-laravel-8 if you want to download this code.
