如何在sonata admin listmapper中添加图像的缩略图

Question

我不知道如何在实体的admin类中的listmapper中预览小图像。我只看到图片编辑表单的链接，但我想看到图片的缩略图。

这是我的实体：

}?>

如果它说“Imagen Es”，我想要图像的缩略图。

Answer 1

$listMapper
->add('thumb', null, array(
    'template' => "ExampleBundle:Pibe:list_thumb.html.twig")
)

在list_thumb.html.twig

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

{% block field %}
    {# {{ dump() }} you can dump all variables here #}
    {# {{ value }} will return the value of getImagenEs() #}
    <img class="img-responsive" alt="{{ object.name }}" src="{{ asset('path/to/uploadfolder/' ~ object.filepath) }}" /> {# or you can use a twig filter with your own logic #}
{% endblock field %}

Answer 2

我相信这是一个更为明确的2日期答案：

protected function configureListFields(ListMapper $listMapper)
{
    $listMapper
        ->addIdentifier('title')
        ->add('image', 'string', ['template' => 'SonataMediaBundle:MediaAdmin:list_image.html.twig'])
        ->add('updatedAt')
        ->add('_action', null, ['actions' =>
            [
                'edit' => [],
                'delete' => []
            ], 'label' => 'Actions']);
}
