How to create database seeder in Laravel 5.8 ?

I think you’re looking for something like the below. Laravel makes it pretty easy to perform seeding , a seeder class contains a run method by default. You can insert data by using a query builder or Eloquent model factories

In this tutorial i will show you how to store your data into database using seeder for testing, we have a super admin table where we can store the super admin credentials.

Step 1: Create table super admin for inserting credentials:

Run this command : php artisan:make migration create_superadmin_table

<?php

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

class CreateSuperadminTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('superadmin', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('email');
            $table->string('password');
            $table->timestamps();
        });
    }

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

After making migration run this command:

Run this command : php artisan migrate

laravel seeder — here you can see we have no data in our superadmin table

Step 2: After this we make a seeder name superadmin seeder for inserting record and save into database:

Run this command : php artisan make:seeder SuperadminSeeder

Now you can see the file database/seeds/SuperadminSeeder.php:

Now define your table name and insert testing data into the SuperadminSeeder

<?php

use Illuminate\Database\Seeder;

class SuperadminSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        DB::table('superadmin')->insert([
            'name' => "superadmin",
            'email' => 'superadmin@yopmail.com',
            'password' => bcrypt('12345678'),
            ]);
    }
}

Step 3: After following these steps call your Seeder into databaseseeder.php file , here you can see:

<?php

use Illuminate\Database\Seeder;

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

Step 3: Now finally your seeder is ready for testing now:
