Laravel 9 Generate Dummy Data Using Factory Tutorial

In this tutorial, you will learn how to generate dummy data into the database tables using factory in laravel 9 application. Please follow the instruction give below:

Install Laravel 9

Setup Database Credential
Create a Model & Migration File
Create New Factory File

Generate Fake Data Using Tinker

Install Laravel 9

First of all we need to create a fresh laravel project, download and install Laravel 9 using the below command

composer create-project --prefer-dist laravel/laravel lara9blog

1	composer create-project --prefer-dist laravel/laravel lara9blog

Configure Database

Now, lets create a MySQL database and connect it with laravel application. After creating database we need to set database credential in application’s .env file.

.env

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=lara9blog
DB_USERNAME=root
DB_PASSWORD=

DB_CONNECTION=mysql

DB_HOST=127.0.0.1

DB_PORT=3306

DB_DATABASE=lara9blog

DB_USERNAME=root

DB_PASSWORD=

Create Model & Migration

Now, we have to define table schema for posts table. Open terminal and let’s run the following command to generate a migration along with model file to create posts table in our database.

php artisan make:model Post -m

1	php artisan make:model Post -m

Once this command is executed you will find a migration file created under “database/migrations”. lets open migration file and put following code in it –

<?php
 
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
 
class CreatePostsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->text('description');
            $table->timestamps();
        });
    }
 
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('posts');
    }
}

<?php

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

class CreatePostsTable extends Migration

{

/**

* Run the migrations.

* @return void

public function up()

{

Schema::create('posts', function (Blueprint $table) {

$table->id();

$table->string('title');

$table->text('description');

$table->timestamps();

});

}

/**

* Reverse the migrations.

* @return void

public function down()

{

Schema::dropIfExists('posts');

}

Next, go to app/Models/Post.php file and add the $fillable property in the Post model as following.

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
 
class Post extends Model
{
    use HasFactory;
 
    protected $fillable = [
        'title', 'description'
    ];
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;

use Illuminate\Database\Eloquent\Model;

class Post extends Model

{

use HasFactory;

protected $fillable = [

'title', 'description'

];

}

Now, run following command to migrate database schema.

php artisan migrate

1	php artisan migrate

After, the migration executed successfully the posts table will be created in database.

Create New Factory File

In this step, we will create a factory file. Run the following command to create factory class named PostFactory by using the following command:

php artisan make:factory PostFactory --model=Post

1	php artisan make:factory PostFactory --model=Post

Go to app/database/factories and open PostFactory.php and put the below code into your file.

<?php
 
namespace Database\Factories;
 
use App\Models\Post;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;
 
class PostFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Post::class;
 
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'title' => $this->faker->title,
            'description' => $this->faker->text,
        ];
    }
}

<?php

namespace Database\Factories;

use App\Models\Post;

use Illuminate\Database\Eloquent\Factories\Factory;

use Illuminate\Support\Str;

class PostFactory extends Factory

{

/**

* The name of the factory's corresponding model.

* @var string

protected $model = Post::class;

/**

* Define the model's default state.

* @return array

public function definition()

{

return [

'title' => $this->faker->title,

'description' => $this->faker->text,

];

}

Run the following command to auto load dependencies.

Generate Fake Data Using Tinker

Please use the following command to generate fake data using tinker:

php artisan tinker

1	php artisan tinker

Now, run following command to generate 100 rows of random Notes.

Post::factory()->count(100)->create()

1	Post::factory()->count(100)->create()
