Sonata Media Bundle : acces media url

问题

I am using sonata media bundle.

and I was wondering how can I access the media url in twig.
I just want the url, I do not need to show the media.

Any suggestions?

回答1:

You have to use the path media helper:

{% path media, 'small' %}

In the above code, media is an instance of the media entity, and small is the chosen format.

But if you do not want to render the media right there and just store the url in a variable, you need to ask the media provider for the public url. This was my case, that I needed to pass the url to another template. I did it creating a custom function in my Twig Extension (see here: http://symfony.com/doc/current/cookbook/templating/twig_extension.html).

Provided that you have the container available in your extension service with $this->container, you can do like this:

public function getMediaPublicUrl($media, $format)
{
    $provider = $this->container->get($media->getProviderName());

    return $provider->generatePublicUrl($media, $format);
}

public function getFunctions() {
     ....
    'media_public_url' => new \Twig_Function_Method($this, 'getMediaPublicUrl'),
     ....
    );
}

And call your new helper form your template:

{% set img_url = media_public_url(media, 'small') %}

for instance

@javigzz's is perfect in case of default context. I used custom context, so had to handle $format first taking into account context name:

$provider = $this->container->get($media->getProviderName());
$format = $provider->getFormatName($media, $format);
$url = $provider->generatePublicUrl($media, $format);

Since @javigzz's answer did not work for me, here is a twig extension that works with the latest version of sonata_media:

namespace Socialbit\SonataMediaTwigExtensionBundle\Twig;

use Sonata\CoreBundle\Model\ManagerInterface;
use Symfony\Component\DependencyInjection\Container;

Class:
/**
 * Description of MediaPathExtension
 *
 * @author thomas.kekeisen
 */
class MediaPathExtension extends \Twig_Extension
{
    /**
     *
     * @var type Container
     */
    protected $container;

    /**
     *
     * @var type ManagerInterface
     */
    protected $mediaManager;

    public function __construct(Container $container, $mediaManager)
    {
        $this->container = $container;
        $this->mediaManager = $mediaManager;
    }

    public function getFunctions()
    {
        return array
        (
            'media_public_url' => new \Twig_Function_Method($this, 'getMediaPublicUrl')
        );
    }

    /**
     * @param mixed $media
     *
     * @return null|\Sonata\MediaBundle\Model\MediaInterface
     */
    private function getMedia($media)
    {
        $media = $this->mediaManager->findOneBy(array(
            'id' => $media
        ));

        return $media;
    }

    public function getMediaPublicUrl($media, $format)
    {
        $media = $this->getMedia($media);

        $provider = $this->container->get($media->getProviderName());

        return $provider->generatePublicUrl($media, $format);
    }

    public function getName()
    {
        return 'SocialbitSonataMediaTwigExtensionBundleMediaPathExtension';
    }
}

services.yml:

services:
    socialbit.sonatamediatwigextensionbundle.mediapathextension:
        class: Socialbit\SonataMediaTwigExtensionBundle\Twig\MediaPathExtension
        public: false
        arguments:
            - @service_container
            - @sonata.media.manager.media
        tags:
            - { name: twig.extension }

The usage will be the same:

{% set img_url = media_public_url(media, 'reference') %}
{{ dump(img_url) }}

回答5:

You can use: {% path media, 'reference' %}

@Blauesocke - tried your solution and had exactly the same result for file provider with using both

{% set img_url = media_public_url(media, 'reference') %}
{{ dump(img_url) }}

and

{%  path sonata_admin.value, 'reference' %}
