列出奏鸣曲管理包中的图像 [英] List Images in sonata admin bundle
问题描述
我是 Symfony 的新手 &试图在奏鸣曲管理包中列出图像.但是我有点困惑如何在树枝文件中获取对象,以便我可以获得图像源的确切路径.
I am new to Symfony & trying to list images in sonata admin bundle. But i am bit confuse how to get an object in twig file so that i can get my exact path for image source.
这是我的代码
protected function configureListFields(ListMapper $listMapper)
{
// $image = $this->getSubject();
$listMapper
->addIdentifier('caption')
->add('image','string', array('template' => 'swaamImageUploaderBundle:Admin:list_image.html.twig'))
;
}
这是我的 list_image.html.twig 文件
and here is my list_image.html.twig file
{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %}
{% block field%}
<img src="{{ 'uploads/images/822b23a922f43bb664cb58ca57de6cccccc962e5.jpeg'}}">
{#<img src="{{ asset(image.getthumbWebPath) }}">#}
{% endblock %}
在我的图像源标签中,我为我的测试提供了一个硬代码路径.但不知道如何从db获取路径.
in my image source tag i have given a hard code path for my testing. but don't know how to get path from db.
另外,当我只在控制器中写入 ->add('image') 时,我会从后端显示的 db 获取我的确切路径.
plus, when i write only ->add('image') in controller i get my exact path from db displayed in back end.
我有一个实体图片.
谁能帮帮我?
推荐答案
我想你正在使用 Sonata Media Bundle
I suppose you're using Sonata Media Bundle
您必须使用实体,您可以在此处找到所需的助手:http://sonata-project.org/bundles/media/2-2/doc/reference/helpers.html
you must use the entity and you can find needed helpers here: http://sonata-project.org/bundles/media/2-2/doc/reference/helpers.html
如果您需要获取控制器中的完整路径(可能发生,很少但可能发生),您必须使用媒体服务
If you need to get the full path in controller (can happen, very rarely but can happen) you have to use the media service
$mm = $this->container->get('sonata.media.manager.media');
$pr = $this->container->get('sonata.media.provider.image');
$media = $mm->findOneBy(array('id' => $idImage));
$format = $pr->getFormatName($media, 'default');
$path = $pr->generatePublicUrl($media, $format);
或使用控制器内的树枝助手
or use the twig helper inside the controller
$format = 'default'; //the format you want to show
$path=$this->get('sonata.media.twig.extension')->path($image, $format);
如果您想将图像添加到 Sonata Admin(您的情况)的列表字段中,您可以使用此代码
if you want to add the image to the list field of Sonata Admin (your case) you can use this code
{% block field %}
{% thumbnail object.image, 'thumb' %}
{% endblock %}
其中 image 是实体的图像 getter 方法(es getImage() )
where image is the image getter method of your entity (es getImage() )
