Laravel, Call to undefined function Database\Seeders\factory()

Question

I get the title error when I run command:

php artisan db:seed

My screenshot:

I have no idea where this problem comes from. I was searching for code examples and solution but I haven't found anything :(

ArticlesTableSeeder.php

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;
// use Laracasts\TestDummy\Factory as TestDummy;

class ArticlesTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        factory(App\Models\Article::class, 30)->create();
    }
}

ArticleFactory.php

<?php

namespace Database\Factories;

use App\Models\Model;
use Illuminate\Database\Eloquent\Factories\Factory;
use Illuminate\Support\Str;

class ModelFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = App\Models\Article::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'title' => $faker->text(50),
            'body' => $faker->text(200)
        ];
    }
}

DatabaseSeeder.php

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;

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

Thank you in advance for your help!

you don't use the `factory` helper function anymore it would seem ... you should check the documentation on how to call these factories https://laravel.com/docs/8.x/database-testing#using-factories — lagbox, Sep 09 '20 at 17:53

In laravel 8 the default route namespace was removed.

Try to change:

ArticlesTableSeeder.php:

 factory(App\Models\Article::class, 30)->create();

to:

\App\Models\Article::factory()->count(30)->create();

ArticleFactory.php:

protected $model = App\Models\Article::class;

to:

protected $model = \App\Models\Article::class;

and you will probably have to change:

 'title' => $faker->text(50),
            'body' => $faker->text(200)

to:

 'title' => $this->faker->text(50),
        'body' => $this->faker->text(200)

You should have mentioned that the helper method `factory()` was removed in Laravel 8 – Emeka Mbah May 04 '21 at 19:30
Thank you Krzysiek_Sadowski This works on Laravel 9 using thinker. \App\Models\Article::factory()->count(30)->create(); – Two Sep 19 '22 at 11:18
This is still working till now. – lothux1987 Mar 24 '23 at 01:51

All suggestions that were mentioned here are correct. Sometimes running composer require laravel/legacy-factories might fix your problem if you're using Laravel 8. Also, in case you get an error that says Class 'Database\Factories\ArticleFactory' not found then make sure you have class ArticleFactory extends Factory and not ModalFactory. And make sure you're using HasFactory in the Article Model like here.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    use HasFactory;
}

If you are using version 8 of laravel, look at the upgrade guide. "Laravel's model factories feature has been totally rewritten to support classes and is not compatible with Laravel 7.x style factories. However, to ease the upgrade process, a new laravel/legacy-factories package has been created to continue using your existing factories with Laravel 8.x. You may install this package via Composer:

composer require laravel/legacy-factories"

https://laravel.com/docs/8.x/upgrade#seeder-factory-namespaces

I'm facing the same issue when I realized my model was not using the HasFactory trait.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;
    
    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'categories';
   
}

So make sure this trait is being used by your model.

This was exactly my problem, thank you! It isn't as clear as it could be in the docs (for me, at least) because I normally look at the code snippets to see what I have to include, whereas in this case it was mentioned in the body of the docs. https://laravel.com/docs/8.x/database-testing#factory-and-model-discovery-conventions – Andrew Fox Jan 19 '22 at 19:43

If you are using version 8 of laravel you can directory use:

use App\Models\Article; Article::factory()->count(30)->create();
