symfony - Adding properties to/extending Sonata Media entity -

i want add properties sonata media entity, can't work. i'm using sonata media bundle 2.3, , have installed according manual. extended sonata easy extends bundle.

when add property application\sonata\mediabundle\entity\media, doesn't picked when run doctrine:generate:diff ('no changes detected in mapping information.').

overriding media class in config.yml won't make difference well.

this code in application\sonata\mediabundle\entity\media.php:

<?php  namespace application\sonata\mediabundle\entity;  use doctrine\orm\mapping orm; use sonata\mediabundle\entity\basemedia basemedia;  /**  * @orm\entity  */ class media extends basemedia {     /**      * @var integer $id      */     protected $id;      /**      * @orm\column(type="string", nullable=true)      */     protected $test;      /**      * @return mixed      */     public function gettest()     {         return $this->test;     }      /**      * @param mixed $test      */     public function settest($test)     {         $this->test = $test;     }      /**      * id      *      * @return integer $id      */     public function getid()     {         return $this->id;     } } 

and in config.yml:

sonata_media:     class:         media: application\sonata\mediabundle\entity\media         gallery: application\sonata\mediabundle\entity\gallery         gallery_has_media: application\sonata\mediabundle\entity\galleryhasmedia 

again, same result if leave section commented out.

update: when create custom migration adds property, when extend mediaadmin, test field won't show when go image edit page:

// application\sonata\mediabundle\admin\mediaadmin.php <?php namespace sonata\mediabundle\admin;  use sonata\adminbundle\admin\admin; use sonata\adminbundle\form\formmapper; use sonata\adminbundle\datagrid\datagridmapper; use sonata\adminbundle\datagrid\listmapper; use sonata\adminbundle\show\showmapper;  class mediaadmin extends admin {     protected function configureformfields(formmapper $formmapper)     {         $formmapper             ->add('name', null, ['required' => false])             ->add('enabled', null, ['required' => false])             ->add('authorname', null, ['required' => false])             ->add('cdnisflushable', null, ['required' => false])             ->add('description', null, ['required' => false])             ->add('copyright', null, ['required' => false])             ->add('test', null, ['required' => false])             ->add('binarycontent', 'file', ['required' => false]);     } } 

so seems sonata ignoring extended media bundle (which isn't case, because when remove application\sonata\mediabundle\entity\media.php, error).

well, seems had remove application/sonata/mediabundle/resources/config/doctrine folder , annotate media entities following:

<?php  namespace application\sonata\mediabundle\entity;  use doctrine\orm\mapping orm; use sonata\mediabundle\entity\basemedia basemedia;  /**  * @orm\table(name="media__media")  * @orm\entity  */ class media extends basemedia 

a simple php app/console doctrine:schema:update --force in end did trick. hope helps encounter same problem.
