如何获取 Sonata 管理包后端列出的图像

我想在列表区域中列出我的图像缩略图，我不知道该怎么做，任何人都可以帮助我。我在后端得到了我的标题。我正在使用 Sonata adim 捆绑包并遵循其官方文档。

这是我的 imageAdmin.php

namespace swaam\ImageUploaderBundle\Admin;

use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Form\FormMapper;

class ImageAdmin extends Admin
{

// Fields to be shown on create/edit forms
    protected function configureFormFields(FormMapper $formMapper)
    {
        $formMapper
            ->add('caption', 'ckeditor', array('label' => 'Ca   ption'))
//            ->add('file', 'entity', array('class' => 'swaam\ImageUploaderBundle\Entity\image'))
            ->add('file', 'file', array('data_class' => 'Symfony\Component\HttpFoundation\File\File'
            ,'property_path' => 'file'
            ))

            ->end(); //if no type is specified, SonataAdminBundle tries to guess it
        ;
    }

// Fields to be shown on filter forms
    protected function configureDatagridFilters(DatagridMapper $datagridMapper)
    {
        $datagridMapper
            ->add('caption')
            ->add('thumbpath')
        ;
    }

// Fields to be shown on lists
    protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
            ->addIdentifier('caption')
//            ->add('thumbpath')
              ->add('thumbpath')
        ;
    }
}

这是更新后我的configureListFields方法

 protected function configureListFields(ListMapper $listMapper)
    {
        $listMapper
//            ->addIdentifier('caption')
//            ->add('thumbpath')
//              ->add('thumbpath')
            ->add('thumbpath', null, array('template' => 'swwamImageUploaderBundle:Admin:list_image.html.twig'))
//            ->add('thumbpath', null, array('template' => 'swwamImageUploaderBundle:Admin:list_image.html.twig'))

        ;
    }

这是我的树枝

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

{% block field%}

    <div>
        {#<img src="{{ image.webPath | imagine_filter('gallery_element_admin') }}" />#}

        //<img src="{{ app.request.scheme ~ '://' ~ app.request.host ~ '/' ~  image.getthumbWebPath }}" />
        {# or whatever to create src of image #}

    </div>
{% endblock %}

最简单的方法是创建自定义管理字段模板。 在配置列表字段方法添加：

->add('path', null, array('template' => 'AcmeBundle:Admin:list_image.html.twig'))

并创建文件AcmeBundle/Resources/views/Admin/list_image.html.twig内容：

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

{% block field%}
    <div>
        <img src="{{ object.webPath | imagine_filter('gallery_element_admin') }}" />
        {# or whatever to create src of image #}
    </div>
{% endblock %}
