如何用新方法扩展Laravel模型，集合？

namespace App\Traits;

trait CustomExtensions
{
    public function scopeFilterByStatus($query, $status)
    {
        return $query->where('status', $status);
    }
}

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\Traits\CustomExtensions;

class User extends Model
{
    use CustomExtensions;
}

$activeUsers = User::filterByStatus('active')->get();

namespace App\Collections;

use Illuminate\Database\Eloquent\Collection;
use App\Traits\CustomExtensions;

class UserCollection extends Collection
{
    use CustomExtensions;
}

namespace App;

use Illuminate\Database\Eloquent\Model;
use App\Collections\UserCollection;

class User extends Model
{
    protected function newCollection(array $models = [])
    {
        return new UserCollection($models);
    }
}
