I followed this tutorial:
https://github.com/KnpLabs/KnpMenuBundle/blob/master/Resources/doc/index.md#installation
And have come across the following error:
An exception has been thrown during the rendering of a template ("Unable to generate a URL for the named route "page_show" as such route does not exist.") in /var/www/bundles/src/Acme/DemoBundle/Resources/views/Default/index.html.twig at line 4.
Is there a step I am missing here to pass something to a controller?
From link:
use Knp\Menu\FactoryInterface;
use Symfony\Component\DependencyInjection\ContainerAware;
class Builder extends ContainerAware
{
public function mainMenu(FactoryInterface $factory, array $options)
{
$menu = $factory->createItem('root');
$menu->addChild('Home', array('route' => 'homepage'));
$menu->addChild('About Me', array(
'route' => 'page_show',
'routeParameters' => array('id' => 42)
));
// ... add more children
return $menu;
}
}
To actually render the menu, just do the following from anywhere in any Twig template:
{{ knp_menu_render('AcmeDemoBundle:Builder:mainMenu') }}
Following the tutorial exactly, this error is caused by line 25 in the file
2 // src/Acme/MainBundle/Menu/MenuBuilder.php
...
25 $menu->addChild('Home', array('route' => 'homepage'));
The tutorial code assumes that you have a route called 'homepage'. Assuming you set this up inside a custom Bundle, then a quick way to solve this problem so you can get the tutorial up and running is to go to...
// src/Acme/MainBundle/Resources/config/routing.yml
...and copy the homepage route from there (will look something like acme_main_bundle_homepage)
