Nette Models not mentioned in the documentation index

Sorry spectator, there might be some confusion. My question is about model files. Are they recommended by Nette or not? There is no mention of them in the documentation. All the database access in the documentation is done via the Presenter.

Yes i can, because i had the same Situation.

I've done this for a JSON Response like this:

A Model Class File in the Folder model named MandatorModel.php

<?php

namespace App\Model;

use Nette;
use App\Model;

class MandatorModel extends Nette\Object
{
	private $database;
	private $session;

	public function __construct(
			Nette\Database\Context $database,
			Nette\Http\Session $session)
	{
		$this->database = $database;
		$this->session = $session;
	}

	/**
	* You should use try and catch
	* @param int $id the ID will search the right Record
	* return obj the dataset for Mandator
	*/
	public function getMandator($id){
		$data = new \stdClass(); // This Class is the Return Object

		try{
			// If database is connected and no Failures throwing
			// Overwrite $data
			$data = $this->database->query("SELECT * FROM mandators WHERE mnd = $id")->fetch();

			if(!$data){ // $data = false because it's empty
				// This will throw a self named Exception (show down the Class MandatorEmptyException)
				// You can add a Number in this Exception for to Proceed further
				throw new MandatorEmptyException("Message",1);
			} else {
				return $data;
			}
		} catch (\PDOException $e) {
			// This Catch Exception will get when PDO-Driver fails
			$data = new \stdClass();
			$data->code = $e->getCode();
			$data->message = $e->getMessage();
			$data->error = true;
			return $data;
		}
	}
}

Class MandatorEmptyException extends \Exception
{}

The Presenter is Important for the Settings in Head-Content

I've used the BasePresenter and extend them. Like this in MandatorPresenter.php

<?php

namespace App\Presenters;

use Nette;
use App\Model;
use Nette\Security\User;


class MandatorPresenter extends BasePresenter
{

	public $httpRequest;
	public $post;
	private $mnd;

	public function __construct(Model\MandatorManager $mnd, Nette\Http\IRequest $httpRequest) {
		$this->httpRequest = $httpRequest;
		$this->post = $this->httpRequest->getPost();
		$this->mnd = $mnd; // MandatorModel
	}

	/* Set the Actions
	 * Important is Prefix action
	 * and the Parameter must named $id
	 * Actions mustn't have a latte File
	 * @param int $id
	*/
	public function actionGet($id){
		$data = new \stdClass(); // send Class $data as JSON Response

		// Call the MandatorModel Function
		$data->mandator = $this->mandator->getMandator($id);

		$this->sendJson($data);
	}
}

The URI will be like this:

yourhost.com/mandator/123456
This get the Mandator as JSON Response

Have a lot of Fun!

Thanks the Guys they teached me here!

@thundervoice btw HttpRequest is already in presenter, you can access it first in startup method.

private $post = [];

public function startup()
{
	$this->post = $this->getHttpRequest()->getPost();
}
