laravel-dompdf - Download PDF On Click

Hey,

I have an event resource and a page which lists all the attendees. I have a requirement where the admin would like to print to pdf of all the attendees.

Controller:

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use App\EventModel;
use App\User;
use App\Mailers\AppMailer;
use Barryvdh\DomPDF\PDF;

    public function index($id)
    {

        $event = EventModel::findOrFail($id);
        $ids = $event->rsvps()->pluck('user_id');
        $attendees = User::whereIn('id', $ids)->get();

        return view('admin.events.attendees.index')->with('attendees', $attendees)
            ->with('event', $event);
    }


    public function printToPDF($eventId)
    {
        $event = EventModel::findOrFail($eventId);
        $ids = $event->rsvps()->pluck('user_id');
        $attendees = User::whereIn('id', $ids)->get();

        $pdf = PDF::loadView('admin.events.attendees.index')->with('attendees', $attendees)->with('event', $event);
        return $pdf->download('event-attendees.pdf');
    }

View:

@extends('admin.layouts.app')

@section('content')
    <div class="container">
        <div class="row">
            <div class="col-md-10 col-md-offset-1">

                        <h4>Attendee List</h4>

                <div class="row">
                    <div class="col-sm-2 pull-right">

                    <div class="col-sm-2 pull-right">

                        @foreach($attendees as $index => $attendee)
                            <tr class="text-center">

                            </tr>
                        @endforeach

                        </tbody>
                    </table>
                </div>

            </div>
        </div>
    </div>
@endsection

Route

    Route::get('/events/{id}/attendees', ['as' => 'admin-event-attendees', 'uses' => 'Admin\EventAttendeesController@index']);
    Route::get('/events/{id}/attendees/print', ['as' => 'admin-event-attendees-print', 'uses' => 'Admin\EventAttendeesController@printToPDF']);

Im having trouble getting to work. First im getting an error

Non-static method Barryvdh\DomPDF\PDF::loadView() should not be called statically, assuming $this from incompatible context

Secondly how do i properly pass in variables when loading the pdf view.

thanks
