name: CI
on: [push]
jobs:

  dusk-php:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

use Facades\App\Contracts\Publisher;
use Illuminate\Database\Eloquent\Model;

class Podcast extends Model
{
    /**
     * Publish the podcast.
     *
     * @return void
     */
    public function publish()
    {
        $this->update(['publishing' => now()]);

        Publisher::publish($this);
    }
}
