问题
I am using Sonata Media Bundle with Symfony2.3 in my project. When I override youtube provider sonata.media.provider.youtube. Everything working fine. No errors or anything but in
/Web/uploads/media
no thumbnails generated but in my admin dashboard show me :
/uploads/media/default/0001/01/thumb_9_default_small.jpg.
I don't know how but when I am not override sonata.media.provider.youtube then thumbnails generated in
/web/uploads/media/
Like :
/web/uploads/media/default/0001/01/thumb_9_default_small.jpg.
I don't know why ?
Here is my config file where I create custom service provider:
services:
sonata.media.provider.youtubecustom:

tags:
- { name: sonata.media.provider }

- @sonata.media.metadata.proxy
calls:
- [ setTemplates, [ { helper_thumbnail: SonataMediaBundle:Provider:thumbnail.html.twig,helper_view: SonataMediaBundle:Provider:view_youtube.html.twig } ] ]
parameters:

'rel' => 0,
// Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay
// when the player loads.
'autoplay' => 0,
// Values: 0 or 1. Default is 0. In the case of a single video player, a setting of 1
// will cause the player to play the initial video again and again. In the case of a
// playlist player (or custom player), the player will play the entire playlist and
// then start again at the first video.
'loop' => 0,

// For more information on the Javascript API and how to use it, see the JavaScript
// API documentation.

// Spacebar: Play / Pause
// Arrow Left: Jump back 10% in the current video
// Arrow Right: Jump ahead 10% in the current video
// Arrow Up: Volume up
// Arrow Down: Volume Down
'disablekb' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables the "Enhanced Genie Menu". This
// behavior causes the genie menu (if present) to appear when the user's mouse enters
// the video display area, as opposed to only appearing when the menu button is pressed.
'egm' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables a border around the entire video
// player. The border's primary color can be set via the color1 parameter, and a
// secondary color can be set by the color2 parameter.

// your embed code for this to work.
'fs' => 1,
// Values: A positive integer. This parameter causes the player to begin playing the video
// at the given number of seconds from the start of the video. Note that similar to the
// seekTo function, the player will look for the closest keyframe to the time you specify.
// This means sometimes the play head may seek to just before the requested time, usually
// no more than ~2 seconds
'start' => 0,
// Values: 0 or 1. Default is 0. Setting to 1 enables HD playback by default. This has no
// effect on the Chromeless Player. This also has no effect if an HD version of the video
// is not available. If you enable this option, keep in mind that users with a slower
// connection may have an sub-optimal experience unless they turn off HD. You should ensure
// your player is large enough to display the video in its native resolution.
'hd' => 1,
// Values: 0 or 1. Default is 1. Setting to 0 disables the search box from displaying when
// the video is minimized. Note that if the rel parameter is set to 0 then the search box
// will also be disabled, regardless of the value of showsearch.
'showsearch' => 0,
// Values: 0 or 1. Default is 1. Setting to 0 causes the player to not display information
// like the video title and rating before the video starts playing.
'showinfo' => 0,

// default, whereas setting to 3 will cause video annotation to not be shown by default.

// to be shown by default, even if the user has turned captions off.

And default youtube service created by Sonata Media Bundle which one I am override :
<service id="sonata.media.provider.youtube" class="%sonata.media.provider.youtube.class%">
<tag name="sonata.media.provider" />
<argument>sonata.media.provider.youtube</argument>
<argument />
<argument />
<argument />
<argument type="service" id="sonata.media.thumbnail.format" />
<argument type="service" id="sonata.media.buzz.browser" />
<argument type="service" id="sonata.media.metadata.proxy" />
<argument />
<call method="setTemplates">
<argument type="collection">
<argument key='helper_thumbnail'>SonataMediaBundle:Provider:thumbnail.html.twig</argument>
<argument key='helper_view'>SonataMediaBundle:Provider:view_youtube.html.twig</argument>
</argument>
</call>
</service>
My Service provider is the same as default youtube provider.
回答1:
Same service name and provider name write in our bundle then problem solved.
Like if you extend YoutubeProvider then same provider name write in your bundle.
See this:
My Config.yml
services:
sonata.media.provider.youtube:
class: %application_sonata_media.youtube_class%
tags:
- { name: sonata.media.provider }
arguments:
- sonata.media.provider.youtube
- @sonata.media.filesystem.local
- @sonata.media.cdn.server
- @sonata.media.generator.default
- @sonata.media.thumbnail.format
- @sonata.media.buzz.browser
- @sonata.media.metadata.proxy
calls:
- [ setTemplates, [ { helper_thumbnail: SonataMediaBundle:Provider:thumbnail.html.twig,helper_view: SonataMediaBundle:Provider:view_youtube.html.twig } ] ]
parameters:
application_sonata_media.youtube_class: Application\Sonata\MediaBundle\Provider\YoutubeProvider
My YoutubeProvider.php
<?php
namespace Application\Sonata\MediaBundle\Provider;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Gaufrette\Filesystem;
use Sonata\MediaBundle\CDN\CDNInterface;
use Sonata\MediaBundle\Generator\GeneratorInterface;
use Buzz\Browser;
use Sonata\MediaBundle\Thumbnail\ThumbnailInterface;
use Sonata\MediaBundle\Metadata\MetadataBuilderInterface;
use Sonata\MediaBundle\Provider\YouTubeProvider as MainYouTubeProvider;
use Sonata\AdminBundle\Form\FormMapper;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Validator\Constraints\NotBlank;
use Symfony\Component\Validator\Constraints\NotNull;
use Sonata\MediaBundle\Model\MediaInterface;
class YoutubeProvider extends MainYouTubeProvider
{
//write provider functions
}
回答2:
It is not the best way to redefine vendors services entirely - this may not work.
There are some common practices in this case (http://symfony.com/doc/current/cookbook/bundles/override.html#services-configuration).
If you want just to redefine the providers class and not change service definition, you only have to change value of parameter sonata.media.provider.youtube.class.
If you want to redefine some part of vendors service (calls, tags etc.) better use CompilerPass.
namespace Acme\DemoBundle\DependencyInjection\Compiler;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;
class OverrideServiceCompilerPass implements CompilerPassInterface
{
public function process(ContainerBuilder $container)
{
$definition = $container->getDefinition('sonata.media.provider.youtube');
$definition->addTag($name, $attributes);
}
}
