Question

我有一个数据库，需要有一个对象的多个图像。在列表视图中，我看到多个图像，但它出现在texte中，我需要有图像!!!

这是我的产品实体的列表映射器（一个带有许多图像的产品）

 /**
 * @param ShowMapper $showMapper
 */
protected function configureShowFields(ShowMapper $showMapper)

{

    $showMapper
        ->with('PRODUCT DESCRIPTION', array('class' => 'col-md-7'))
        ->add('name')
        ->add('country')
        ->add('descriptionshortnat', null, array('label' => 'Description short (national)'))
        ->add('descriptionlongnat', null, array('label' => 'Description long (national)'))
        ->add('descriptionshorten', null, array('label' => 'Description short (english)'))
        ->add('descriptionlongen', null, array('label' => 'Description long (english)'))
        ->add('created')
        ->add('updated')
        ->end()

        ->with('PICTURES', array('class' => 'col-md-5'))
        ->add('image', 'string' , array("template"=>"AdminBundle::Admin/list_types/image.html.twig"))
        ->end()

        ->with('CLASSIFICATION', array('class' => 'col-md-5'))
        ->add('category')
        ->add('preservation', null, array('label' => 'Preservation method'))
        ->add('population', null, array('label' => 'Population target'))
        ->add('innovation')
        ->add('timeframe', null, array('label' => 'Comsumer timeframe'))
        ->add('component')
        ->end()
        ->with('PARTNERS', array('class' => 'col-md-5'))
        ->end()             
        ->with('COMPETITION', array('class' => 'col-md-5'))
        ->add('contact', 'sonata_type_model', array('required' => false, 'multiple' => true,'label' => 'Student team'))
        ->add('organisation', 'sonata_type_model', array('required' => false))
        ->add('competition', 'sonata_type_model', array('required' => false, 'multiple' => true))
        ->end()



    ;
}

}

这是我的'形象'的枝条

{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %}

{% block field %}
    <a href="{{ asset('uploads/documents/') }}{{ value|nl2br }}"><img class="admin-list-preview" src="{{ asset('uploads/documents/') }}{{ value|nl2br }}"/></a>
{% endblock %}

    // sanitize it at least to avoid any security issues

}

protected function getUploadRootDir()
{
    // the absolute directory path where uploaded
    // documents should be saved
    return __DIR__.'/../../../web/'.$this->getUploadDir();

}

protected function getUploadDir()
{
    // get rid of the __DIR__ so it doesn't screw up
    // when displaying uploaded doc/image in the view.
    return 'uploads/documents';

  }

}

感谢帮助我，

我需要看到我的照片（图片）而不是文字!!!

SCREEN SHOT OF THE DUMP()

Answer 1

如果你不会看到你的形象 - 使用这种结构：

{{ asset('uploads/documents/' ~ object.image ) }}
uploads/documents/ - folder to you directory with images.
object.image - image name (twig variable)

SonataAdminBundle的示例

{% for image in object.image %} 
     <img class="admin-list-preview" src="{{ asset('uploads/documents/' ~ image) }}"/> 
{% end for %}
