Use Database Seeding

[KenHuangisGood]

When I use php artisan db:seed to add RolesAndPermissionsSeeder, I got this

 Illuminate\Contracts\Container\BindingResolutionException 

  Target class [Database\Seeders\RolesAndPermissionsSeeder] does not exist.

• My Step
  1. start new Laravel project
  2. install nova and create new nova user
  3. Your Installation step
  4. php artisan vendor:publish --provider="Sereny\NovaPermissions\ToolServiceProvider" --tag="seeds"
  5. copy your example seeder code
  6. add $this->call(RolesAndPermissionsSeeder::class) to DatabaseSeeder.php
  7. run php artisan db:seed

I'm not sure if I gave the wrong instructions, but in any case, I have managed to solve this problem.

• My Solve
  1. move RolesAndPermissionsSeeder.php from database/seeds to database/seeders
  2. add namespace Database\Seeders; in RolesAndPermissionsSeeder.php
  3. run php artisan db:seed
