Question

I've been trying to get my seeder to work but it keeps giving me the following error
Call to undefined function Database\Seeders\factory()

return $this->belongsTo('App\Models\Contact');
}
}
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 1

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 Database\Factories;
use App\Models\Contact;
use Illuminate\Database\Eloquent\Factories\Factory;
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', $max = 'now')
];
}
}
In seeders use factory like that:
<?php
namespace Database\Seeders;
use Illuminate\Database\Seeder;
class ContactTableSeeder extends Seeder
{
/**
* Run the database seeds.
*
* #return void
*/
public function run()
{
App\Models\Contact::factory()->create(100)
->each(function($contact) {
$contact->addresses()->save(
App\Address::factory()->make()
);
});
}
}

Answer 2

Replace your factory function factory('App\Models\Contact', 100)->create()
with this code:
\App\Models\Contact::factory()->count(100)
->create();
Why? Because In laravel 8 the default route namespace was removed

Answer 3

In laravel 8 the default route namespace was removed.
Try to change
factory(App\Models\Contact::class,100)->create();
To
\App\Models\Contact::factory()->create();
\App\Models\Contact::factory(100)->create(); \\If you want to create 100 number of record then
