redrawControl() in component

Eijliaan

Hi,
I have this component

<?php
use Nette,
    App\Model;

class Rating extends Nette\Application\UI\Control {

    private $presenter;
    private $context;

    public function __construct($presenter, $context) {
        parent::__construct($presenter, $context);
        $this->presenter = $presenter;
        $this->context = $context;
    }

    public function renderAdd() {
        $this->template->rating = 'some rating...';
        $this->template->setFile(dirname(__FILE__) . "/default.latte");
        $this->template->render();
    }

    public function handleRate() {
        if ($this->isAjax()) {
            $this->template->rating = 'new rating...';
            $this->presenter->redrawControl('rating');
        }
    }

}
?>

with this template

<a href="{link rate!}" class="ajax">Rate</a>
{snippet rating}
   {$rating}
{/snippet}

called in main template like {control rating:add}.

The problem is when I click on the link, the {snippet rating} will not redraw itself (the response is {"state":[]}). When snippet is in component, it has ID like snippet-componentName-snippetName, instead of snippet--componentName-snippetName (this way is it in main templates, without componentName of course).

I have also tried to change handle to this

<?php
public function handleRate() {
    if ($this->isAjax()) {
        $this->template->rating = 'new rating...';
        $this->redrawControl('rating');
        $this->template->setFile(dirname(__FILE__) . "/default.latte");
        $this->template->render();
    }
}
?>

It returns a response at least (HTML code), but the snippet is still no redrawn.

Any ideas what am I doing wrong?

Hi, place snippets into component's template:

{snippet}
..

{/}

And in control's handle call:

$this->redrawControl();

That should be enough.

It Works! Thank you :) I
I had to add these lines too to make it work properly.

<?php
    public function render() {
        $this->template->setFile(dirname(__FILE__) . "/default.latte");
        $this->template->render();
    }
?>
