Automatic installation of the variable in all templates

How to load a variable in all the templates?

abstract class BasePresenter extends Nette\Application\UI\Presenter
{
    public function __construct() {
        $this->template->u = $this->session->getSection('user')->user;
    }
}

Throws:

Call to a member function getByType() on a non-object.
File: ...\libs\Nette\Application\UI\Presenter.php   Line: 1433

and

abstract class BasePresenter extends Nette\Application\UI\Presenter
{
    public function __construct() {
        parent::__construct();
        $this->template->u = $this->session->getSection('user')->user;
    }
}

Throws:

Argument 1 passed to Nette\Application\UI\Presenter::__construct() must implement interface Nette\DI\IContainer,
none given, called in \path\to\app\presenters\BasePresenter.php on line 13 and defined

~~You forgot to call parent::__construct(); first. But that's not the ideal solution.~~ Move your code to beforeRender() method.

protected function beforeRender()
{
	parent::beforeRender();
	$this->template->u = $this->session->getSection('user')->user;
}

Presenters will be refactored in close future, but now it's better to avoid using presenter's constructor.

It helped. Thank you very much.

Btw, the $user variable is passed to presenter templates and presenter components' templates automatically (it is filled with instance of Nette\Security\User).

Even better approach to this is to rewrite the createTemplate() method…

protected function createTemplate($class = NULL)
{
	$template = parent::createTemplate($class);
	$template->u = $this->getSession('user')->user;
	return $template;
}
