laravel seeder is giving an error and won’t seed

I’ve been trying to get my seeder to work but it keeps giving me the following error

 Call to undefined function DatabaseSeedersfactory()

    public function addresses()

My Address Model

<?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;

class Address extends Model
{
    use HasFactory;
    protected $fillable = [ 'id', 'number', 'street', 'city', 'state', 'zip', 'type', 'contact_id' ];

    public function contacts()
    {
        return $this->belongsTo('AppModelsContact');
    }
}

I have tried running composer dump-auto composer update

None of those normal fixes seem to work.

I really have no idea why its failing Thanks in advance for your help

Answer

In Laravel8, you need to update your factory files like below or add laravel/legacy-factories package to your project. Further info: https://laravel.com/docs/8.x/upgrade#model-factories

<?php

namespace DatabaseFactories;

use AppModelsContact;
use IlluminateDatabaseEloquentFactoriesFactory;

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

    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'firstName' => $this->faker->firstName,
            'lastName' => $this->faker->lastName,
            'email' => $this->faker->unique()->email,
            'phone' => $this->faker->phoneNumber,
            'birthday' => $this->faker->date($format = 'Y-m-d', $max = 'now')
        ];
    }
}

In seeders use factory like that:

<?php

namespace DatabaseSeeders;

use IlluminateDatabaseSeeder;

class ContactTableSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        AppModelsContact::factory()->create(100)
            ->each(function($contact) {
                $contact->addresses()->save(
                    AppAddress::factory()->make()
                );
        });
    }
}
