I am unable Model Factory in Laravel Tinker.

//ItemFactory.php

class ItemFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = Item::class;

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'slug' => $this->faker->slug(5, true),
            'code' => $this->faker->words(5, true),
            'description' => $this->faker->sentence,
            'price' => $this->faker->randomNumber(1000, 10000),
            'size' => $this->faker->randomElement(['Small', 'Medium', 'Large',]),
        ];
    }
}

Inside Tinker

>>> factory(App\Item::class)->create();

It throws me an error:

PHP Fatal error: Call to undefined function factory() in Psy Shell code on line 1

In Laravel 8.x release notes:

Eloquent model factories have been entirely re-written as class based factories and improved to have first-class relationship support.

Global factory() function is removed as of Laravel 8. Instead, you should now use model factory classes.

  1. Create a factory:
php artisan make:factory ItemFactory --model=Item
  1. Make sure that Illuminate\Database\Eloquent\Factories\HasFactory trait is imported in your model:
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Item extends Model
{
    use HasFactory;

    // ...
}
  1. Use it like this:
$item = Item::factory()->make(); // Create a single App\Models\Item instance

// or

$items = Item::factory()->count(3)->make(); // Create three App\Models\Item instances

Use create method to persist them to the database:

$item = Item::factory()->create(); // Create a single App\Models\Item instance and persist to the database

// or

$items = Item::factory()->count(3)->create(); // Create three App\Models\Item instances and persist to the database

Being said that, if you still want to provide support for the previous generation of model factories within Laravel 8.x, you can use laravel/legacy-factories package.

After going through the documentation of Model Factory, there were major changes in Laravel 8 version.

For using Model Factory anywhere inside Laravel 8:

  1. Inside Model, we need to import the Illuminate\Database\Eloquent\Factories\HasFactory trait

  2. New command to implement the factory

App\Item::factory()->create();

In laravel 8 the default route namespace was removed.

Try to change command

factory(App\Item::class)->create();

To

\App\Models\Item::factory()->create(); 
\App\Models\Item::factory(10)->create(); \\If you want to create specify number of record then

In Laravel 8 I couldn't get the factory method to work just calling it straight out but I was able to get it to work by calling it like a static method on the Item class:

Terminal:

Item::factory()->create();
