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!

Answer 1

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)

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; }
