Upgrading Laravel 7 to 8, seeder issue-CodePudding

I am seeing a lot of issues with the upgrade path from Laravel 7 to 8, but I encounter a different problem for which I cannot find an answer.

It is this one

Seeding: Database\Seeders\UsersTableSeeder

   Error 

  Call to undefined method Database\Factories\UserFactory::new()

  at vendor/laravel/framework/src/Illuminate/Database/Eloquent/Factories/Factory.php:737

CodePudding user response：

You have probably read in the Upgrade Guide from 7 to 8 that Factories and Seeders are changed in Laravel 8.

If you don't have many Factories and Seeders you can write them from scratch.

CodePudding user response：

I extended the wrong Factory class.

The one I was using was Faker\Factory but instead I must use Illuminate\Database\Eloquent\Factories\Factory.

It was probably because I used the 'import class' function of PHPStorm too quickly.
