    ];
});

added the solution of

"user factory seems to be missing /* @var $factory \Illuminate\Database\Eloquent\Factory */ at the top. Maybe that is the culprit. – user3532758"

and got this error

tried to do the same thing as in the course, and did not worked my code:

course code:

user factory seems to be missing `/* @var $factory \Illuminate\Database\Eloquent\Factory */` at the top. Maybe that is the culprit. — user3532758, Jul 25 '21 at 02:17
it is weird because in the last image (course) the instructor does not include anything as seen there in the screenshot, however i will try whatever suggestion you bring here — swm, Jul 25 '21 at 03:04
Does [this](https://stackoverflow.com/questions/65720055/undefined-variable-factory-laravel-8-livewire) answer your question? — Doğuş, Jul 25 '21 at 03:29
Does this answer your question? ["Notice: Undefined variable", "Notice: Undefined index", and "Notice: Undefined offset" using PHP](https://stackoverflow.com/questions/4261133/notice-undefined-variable-notice-undefined-index-and-notice-undefined) — Martin Zeitler, Jul 25 '21 at 03:40
Just revert file `UserFactory.php` to it's original content ... this isn't a valid PHP class. — Martin Zeitler, Jul 25 '21 at 03:47
1. `@var..` should be between `/*` and `*/`. 2. If it is Larvel 8, factory definitions will be completely different; UserFactory would have a separate class where definitions would go inside a definitions() function. https://laravel.com/docs/8.x/database-testing#concept-overview (the previous versions might work but I have never tried and no promises) — user3532758, Jul 25 '21 at 04:16
https://laravel.com/docs/8.x/upgrade#model-factories use `composer require laravel/legacy-factories` to use legacy style factories — apokryfos, Jul 25 '21 at 10:19
tried : use composer require laravel/legacy-factories , ran php artisan db:seed still getting the: ErrorException Undefined variable: factory at D:\Repositorio\ApiRestful\database\factories\UserFactory.php:11 7▕ use App\Seller; 8▕ 9▕ /*@var \Illuminate\Database\Eloquent\Factory $factory*/ 10▕ ➜ 11▕ $factory->define(User::class, function (Faker\Generator $faker) — swm, Jul 25 '21 at 15:50
Ok saw this video, https://www.youtube.com/watch?v=Qrff3Qiy2yk , so basically do i have to create a factoryClassFile.php for every class? for example, i have this code: https://jsfiddle.net/p2h6otcr/ do i have to create a factoryfile for every model CLASS? for example, USER.php and CATEGORY.php ? thank in foward — swm, Jul 25 '21 at 16:33
