Backend Template Anpassung

[derRenner]

Hallo,

in einer Erweiterung möchte ich das Backendtemplate anpassen - leider wird mir die Anpassung nicht angezeigt.

<?php

// src/Controller/ContentElement/DividerController.php

declare(strict_types=1);

namespace Berecont\ContaoDividerBundle\Controller\ContentElement;

use Contao\BackendTemplate;
use Contao\ContentModel;
use Contao\CoreBundle\Controller\ContentElement\AbstractContentElementController;
use Contao\CoreBundle\ServiceAnnotation\ContentElement;
use Contao\Template;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

/**
 * Class DividerController
 *
 * @ContentElement(DividerController::TYPE, category="werbepanorama", template="ce_divider")
 */
class DividerController extends AbstractContentElementController
{
    public const TYPE = 'divider';

    protected function getResponse(Template $template, ContentModel $model, Request $request): ?Response
    {
        
    $template->dividerWidth = $model->dividerWidth;
     ....

    }

    public function generate()
    {
        if (TL_MODE === 'BE') {
            $template = new \BackendTemplate('be_wildcard');
            $template->wildcard = '### Trennlinie ' . $template->dividerWidth . ' ###';

            return $template->parse();
        }

        return parent::generate();
    }
}

Muss ich an anderer Stelle noch eine Einstellung vornehmen?
Wo liegt mein Fehler?
Vielen Dank für die Hilfestellung

Statt TL_MODE solltest du den ScopeMatcher verwenden:

namespace App\Controller\ContentElement;

use Contao\BackendTemplate;
use Contao\ContentModel;
use Contao\CoreBundle\Controller\ContentElement\AbstractContentElementController;
use Contao\CoreBundle\Routing\ScopeMatcher;
use Contao\CoreBundle\ServiceAnnotation\ContentElement;
use Contao\Template;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

/**
 * @ContentElement(category="texts")
 */
class MyContentElementController extends AbstractContentElementController
{
    private $scopeMatcher;

    public function __construct(ScopeMatcher $scopeMatcher)
    {
        $this->scopeMatcher = $scopeMatcher;
    }

    protected function getResponse(Template $template, ContentModel $model, Request $request): ?Response
    {
        if ($this->scopeMatcher->isBackendRequest($request)) {
            $template = new BackendTemplate('be_wildcard');
            $template->wildcard = '### FOOBAR ###';

            return new Response($template->parse());
        }

        // …
        
        return new Response($template->parse());
    }
}

will bei mir nicht
angemeckert wird public function __construct(ScopeMatcher $scopeMatcher)

Fehler im Backend - DebugMode:

Too few arguments to function Berecont\ContaoDividerBundle\Controller\ContentElement\DividerController::__construct(), 0 passed in C:\laragon\www\dev411\var\cache\dev\ContainerMAgjD5U\getContao_Fragment_Contao_ContentElement_DividerService.php on line 28 and exactly 1 expected 

Der Beispielcode von mir ist für eine Applikationsanpassung, wo du dich nicht selbst um Dependency Injection kümmern musst. In deinem Bundle musst du das schon - oder zumindest dediziert Autowiring aktivieren. Wie sieht deine Service Definition aus?

[derRenner]

Wie sieht deine Service Definition aus?

meinest du Resources/config/services.yml?

services:

    # Contao content element Berecont\ContaoDividerBundle\Controller\ContentElement\DividerController
    # We used annotations for tagging the frontend element category, the frontend element type and the frontend element template
    Berecont\ContaoDividerBundle\Controller\ContentElement\DividerController:
        tags:
            - { name: container.service_subscriber }
        public: true
        # Since Symfony 5 the container has to be set manually
        calls:
            - [ setContainer, [ '@Psr\Container\ContainerInterface' ] ] 

Ich möchte an dieser Stelle vermerken, dass ich über die Erweiterung [markocupic/contao-bundle-creator-bundle] arbeite und hier wiederum mit den dabei entstandenen Dateien.

[Spooky]

Ein paar Anmerkungen dazu:

• Du hast deinen Service mit container.service_subscriber getagged, hast aber gar keine Services subscribed. Das kannst du entfernen.
• Du lässt den Container setzen, das brauchst du aber auch nicht, weil du diesen nicht (direkt) benutzt.
• Dein Konstruktor verlangt momentan nach dem ScopeMatcher Service, das hast du in deiner Service Definition noch nicht eingefügt. Alternativ kannst du auch autowiring für den Service aktivieren, dann musst du das nicht manuell machen.

[derRenner]

meine service.yml sieht nun so aus - Error bleibt

services:

    # Contao content element Berecont\ContaoDividerBundle\Controller\ContentElement\DividerController
    # We used annotations for tagging the frontend element category, the frontend element type and the frontend element template
    Berecont\ContaoDividerBundle\Controller\ContentElement\DividerController:
        public: true
        autowire: true 

Ich hätte auch versucht ein use Contao\CoreBundle\Routing\ScopeMatcher; in der DividerController.php einzufügen - auch erfolglos.


Wenn mein Fehler einfach zu eruieren ist, dann würde ich hier weiter machen - ansonsten ignoriere ich hier mal die Möglichkeit das Backend angepasst angezeigt zu bekommen

[Spooky]

Statt public: true nimm autoconfigure: true. Hast du danach composer install ausgeführt?

[derRenner]

Auch dieses Problem konnte gelöst werden.

Ich musste auch zusätzlich noch use Contao\CoreBundle\Routing\ScopeMatcher; mit in die Datei DividerController.php einfügen.
