In this post, I am going to explain about creating dummy data in the database by using Laravel Eloquent Factory and Seed The Database by using Database Seeder.

Eloquent Factory

Eloquent Factory is nothing but an image of a Model with fake data.

To create a model factory you have to run the command below.

php artisan make:factory UserFactory --model=User

This will generate the file in database/factory/UserFactory.php

Now let's add fake data for each column.

<?php

namespace Database\Factories;

use Illuminate\Support\Str;
use Illuminate\Support\Facades\Hash;
use Illuminate\Database\Eloquent\Factories\Factory;

/**
 * @extends \Illuminate\Database\Eloquent\Factories\Factory<\App\Models\User>
 */
class UserFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition()
    {
        return [
            "name" => $this->faker->name(),
            "email" => $this->faker->unique()->safeEmail(),
            "username" => $this->faker->unique()->userName(),
            "mobile_no" => $this->faker->phoneNumber(),
            "password" => Hash::make("Password"),
            "email_verified_at" => now(),
            "remember_token" => Str::random(10)
        ];
    }
}

Now to run the factory you can use Laravel Tinker.

In the terminal, you can run the command below to enable Laravel Tinker.

php artisan tinker

Now run the factory using the model to generate a single record with fake data.

App\Models\User::factory()->create();

To generate more than one record you have to specify the count for records.

App\Models\User::factory()->count(10)->create();

DB Seeder

To make a seeder For UserTableSeeder by running the command below.

php artisan make:seed UserTableSeeder

This command generate a file in database/seeders/UserTableSeeder.php

Next Update the run function of the seeder file.

<?php

namespace Database\Seeders;

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

class UserTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        User::factory()->count(1000)->create();
    }
}

Now Run the command below to seed the data,

php artisan db:seed --class=UserTableSeeder
