How do I instantiate and use a $session variable? I cant get through the documentation

Timon

Hi, I am really novice in php and nette though I am learning and liking it.
I wish to know how to set a session and set values. The following is a copy paste from the documentation and it is just giving errors!!

namespace App\Presenters;

use Nette;
use App\Model;
use Nette\Application\UI\Form;
use Nette\Http\SessionSection;


class HomepagePresenter extends BasePresenter
{
    private $database;
    private $session;
    private $sessionSection;

    public function __construct(Nette\Database\Context $database, Nette\Http\Session $session)
    {
        $this->database = $database;
		$session = $this->getSession(); // I dont understand this
        $mySection = $this->getSession('mySection'); //I dont understand this
    }

	// function that calls loginFormSucceeded

	public function loginFormSucceeded($form, $values)
    {
		//login
		//if login set sessions

		// variable writing
		$section->userName = 'franta'; //Why use $section yet we used $session above??!!
	}
}

It may seem very easy to most of you but I just cant get my head round it.
A sample presenter class with database and session will really help.
Please help. Thanks

Presenter already has session. So you dont need to inject it via constructor.
In the action method you can use session.

public function actionDefault ()
{
    $this->getSession()->myVar = 'myValue';
}
