php - Symfony SonataMediaBundle add Gallery only of ImageProvider Media -

i'm using sonatamediabundle , want add gallery of images entity, let's ad. each ad has gallery can have multiple media. i've been following this other answer, , has been pretty useful.

i did already, can add galleries entity , add sort of media gallery, want in backend skip provider selection when media added gallery, , automatically select imageprovider, can create image-only gallery.

class ad {     /**      * @var int      *      * @orm\column(name="id", type="integer")      * @orm\id      * @orm\generatedvalue(strategy="auto")      */     private $id;      /**      * @var string      *      * @orm\column(name="title", type="string", length=255,nullable=true)      */     private $adtitle;      /**      * @galleryhasmorethanninemedia      * @orm\onetoone(targetentity="application\sonata\mediabundle\entity\gallery",mappedby="ad",cascade={"persist"})      * @orm\joincolumn(name="gallery", referencedcolumnname="id",nullable=true)      */     private $gallery; } 

and in ad sonata admin class:

 protected function configureformfields(formmapper $formmapper)     {         $formmapper             ->add('adtitle')                ->add('gallery', 'sonata_type_model_list', array(                 'cascade_validation' => true,                 'required' => false,             ), array(                     'edit' => 'inline',                     'inline' => 'table',                     'sortable' => 'position',                     'link_parameters' => array('provider' => 'sonata.media.provider.image'),                     'admin_code' => 'sonata.media.admin.gallery',                 )             );     } 

somehow need pass link_parameters not gallery form, each galleryhasmedia being created, each of new media image of imageprovider , gets validation of provider(the extensions,mime type, thumbnail etc.)

so how form looks like

which opens modal window can add galleryhasmedia gallery.

what want upon adding media, modal choose provider not appear, instead select imageprovider automatically. possible pass link_parameters' => array('provider' => 'sonata.media.provider.youtube') inside nested form value in admin class?

is possible? have modify in admin class or overwrite other form/class?

added sonatamedia configuration:

sonata_media:     # if don't use default namespace configuration     #class:     #    media: myvendor\mediabundle\entity\media     #    gallery: myvendor\mediabundle\entity\gallery     #    gallery_has_media: myvendor\mediabundle\entity\galleryhasmedia     db_driver: doctrine_orm # or doctrine_mongodb, doctrine_phpcr mandatory choose 1 here     default_context: default # need set context     contexts:         default:  # default context mandatory             providers:                 - sonata.media.provider.dailymotion                 - sonata.media.provider.youtube                 - sonata.media.provider.image                 - sonata.media.provider.file                 - sonata.media.provider.vimeo             formats:                 small: { width: 100 , quality: 70}                 big:   { width: 500 , quality: 70}         profile_pics:  # default context mandatory             providers:                 - sonata.media.provider.image             formats:                 small: { width: 100 , quality: 70}                 big:   { width: 500 , quality: 70}         personal_albums:             download:                 strategy: sonata.media.security.private_strategy                 mode: http             providers:                 - sonata.media.provider.image                 - sonata.media.provider.file                 - sonata.media.provider.private             formats:                 default:  { width: 100 , quality: 70}     cdn:         server:             path: %cdn_server_path% # http://media.sonata-project.org/      filesystem:         local:             directory:  %kernel.root_dir%/../web/uploads/media             create:     true     providers:         #image:         #    resizer: false         file:             service:    sonata.media.provider.file             resizer:    false             filesystem: sonata.media.filesystem.local             cdn:        sonata.media.cdn.server             generator:  sonata.media.generator.default             thumbnail:  sonata.media.thumbnail.format             allowed_extensions: ['mp4','pdf', 'txt', 'rtf', 'doc', 'docx', 'xls', 'xlsx', 'ppt', 'pttx', 'odt', 'odg', 'odp', 'ods', 'odc', 'odf', 'odb', 'csv', 'xml']             allowed_mime_types: ['video/mp4','application/pdf', 'application/x-pdf', 'application/rtf', 'text/html', 'text/rtf', 'text/plain']     buzz:         connector:  sonata.media.buzz.connector.file_get_contents  doctrine:     orm:         entity_managers:             default:                 mappings:                     applicationsonatamediabundle: ~                     sonatamediabundle: ~ 

try this.

config.yml here define allowed providers:

sonata_media:      #...      contexts:          #...          your_context:             providers:                 - sonata.media.provider.image              formats:                 admin: { width: 55 , height: 55 , quality: 80}                 small: { width: 75 , quality: 80}                 medium: { width: 125 , quality: 80}                 big: { width: 265 , quality: 80}

entityadmin.php here define custom context allowed providers:
