Hi, I am following this guide: https://doc.nette.org/…ase-explorer
section “Filtering by another table value”

This is my presenter with DI context

<?php
declare(strict_types = 1);

namespace App\Presenters;

use Nette;
use Nette\Application\UI\Form;

final class SeatPresenter extends Nette\Application\UI\Presenter {

    /** @var Nette\Database\Context */
    private $database;

   public function __construct(Nette\Database\Context $database) {
        $this->database = $database;
    }
    public function createToday(){
        $today = date("Y/m/d");
        return $today;
    }

    public function renderDefault() {
        $today = $this->createToday();
        $seat = $this->database->table('bookevent');
        $seat->where('bookdate.date',$today);
        $this->template->seat = $seat;

    }


}

These are my tables, which follow the naming convention:

MariaDB [dashboard]> show tables;

Does your bookevent table have foreign key to tables bookdate and bookdesk? If not, add them, clear cache and try again.

Nightfish, youre great! Thanks! That worked!

For anyone who comes here to check, this was the command:

MariaDB [dashboard]> alter table bookevent
    -> add constraint FK_BookdateBookevent
    -> foreign key (bookdate_id) references bookdate(id);
Query OK, 8 rows affected (0.019 sec)
Records: 8  Duplicates: 0  Warnings: 0
