LiipImagineBundle和'filter not defined'

Question

我安裝了LiipImagineBundle。

config.yml：

liip_imagine: 
    filter_sets: 
     my_thumb: 
      quality: 75 
      filters: 
       thumbnail: { size: [120, 90], mode: outbound } 

AppKernel.php：

$bundles = array(
     ... 
     new Liip\ImagineBundle\LiipImagineBundle(), 
    ); 

當我要使用過濾器：

<td><img src="{{ asset('images/zestawy/'~entity.zdjecie) | imagine_filter('my_thumb') }}" /></td> 

我得到這個錯誤：

An exception has been thrown during the rendering of a template ("Filter not defined: my_thumb") 

什麼錯了？

Answer 1

你在routing.yml中設置了路由嗎？

_imagine: 
    resource: . 
    type:  imagine 

還要確保您清除緩存

php app/console cache:clear --env="dev" 
php app/console cache:clear --env="prod"
