可能应该被命名为：“SonataMediaBundle-缺失的howto在哪里？”。
我使用了sonataAdminBundle和sonataDoctrineORMAdminBundle（以及其他一些）来创建一些管理后台，大部分事情都按预期工作，但我把文件上传和处理留到了后面，因为我认为“这有多难呢？”。
长话短说-是否有任何关于最简单的事情的文档-i.e.如何将图片附加到帖子或条目，如何配置sonata admin类，如何在编辑表单中显示图像缩略图等？
文档的第一页以“您可以访问您的管理仪表板”结束，好像我可以在那里期望一些相关的更改，也许是媒体管理器正在运行，或者其他什么。但实际上并不是这样。
下一页简要介绍了助手，然后是另一页，涉及相当复杂的vimeo提供商案例研究。
我在网上搜索了所有内容，最好的结果是使用ajax弹出窗口的上传字段和已上传文件列表。
在我的管理类中，我有：
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->with('general')
->add('title')
->add('body')
->add('categories')
->end()
->with('media')
->add('images', 'sonata_type_model')
在我的News类中：
/**
* @ORM\ManyToMany(targetEntity="Application\Sonata\MediaBundle\Entity\Media")
*/
public $images;
所有的yaml配置和路由都已经实现。
结果是：在尝试上传图片时，选择图片id列表并带有“加号”标志（我猜这是sonata_type_model字段）会显示错误消息：Fatal error: Call to a member function add() on a non-object in [some-entity].php。
我被卡住了。我用sf2只花了一两个小时就创建了一个媒体“管理器”，但那是另一个项目，将当前项目重写为这种模式意味着从头开始。所以 - 为了使sonataMediaBundle与sonataAdminBundle正常工作，该怎么办？
编辑：这是我所做的：

正如您所见，大部分内容都是从Symfony2教程中复制的。
现在，让我们来看控制器：
<?php
namespace Some\SiteBundle;
use Some\SiteBundle\Form\Type\ImageShowType;
use Some\SiteBundle\Entity\Document;
use Sonata\AdminBundle\Admin\Admin;
use Sonata\AdminBundle\Datagrid\ListMapper;
use Sonata\AdminBundle\Datagrid\DatagridMapper;
use Sonata\AdminBundle\Validator\ErrorElement;
use Sonata\AdminBundle\Form\FormMapper;
use Sonata\AdminBundle\Show\ShowMapper;
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\Request;
class NewsAdmin extends Admin
{
public function __construct($code, $class, $baseControllerName) {
parent::__construct($code, $class, $baseControllerName);
$this->setFormTheme(array_merge($this->getFormTheme(),
array('FestusSiteBundle:Form:image_form.html.twig')
));
}
protected function configureFormFields(FormMapper $formMapper)
{
$formMapper
->with('ogólne')
->add('title', NULL, array('label' => 'tytuł:'))
->add('body', NULL, array('label' => 'treść:', 'attr' => array(
'class' => 'tinymce', 'data-theme' => 'simple')))
->add('categories', NULL, array('label' => 'kategorie:'))
->end()
->with('media')
->add('fileName', 'text', array(
"label" => 'tytuł obrazka:',
'property_path' => false,
'required' => false
))
->add('theFile', 'file', array(
"label" => 'wybierz plik',
'property_path' => false,
'required' => false
))
->end()
;
}
protected function configureDatagridFilters(DatagridMapper $datagridMapper)
{
$datagridMapper
->add('title')
->add('body')
;
}
protected function configureListFields(ListMapper $listMapper)
{
$listMapper
->addIdentifier('title')
->add('categories')
->add('_action', 'actions', array(
'actions' => array(
'view' => array(),
'edit' => array(),
)
))
;
}
protected function configureShowFields(ShowMapper $showMapper)
{
$showMapper->add('title')
->add('body');
}
public function validate(ErrorElement $errorElement, $object)
{
$errorElement
->with('title')
->assertMinLength(array('limit' => 2))
->end()
;
}
public function prePersist($news) {
$this->saveFile($news);
}
public function preUpdate($news) {
$this->saveFile($news);
}
public function saveFile($news) {
$request = Request::createFromGlobals();
$requestData = current($request->request->all());
$filesData = current($request->files->all());
$document = new Document();
$theFile = $filesData['theFile'];
$name = $requestData['fileName'];
if($theFile != NULL){
$document->setName($name);
$document->setTheFile($theFile);
$news->setDocument($document);
}
}
}
我的基础包类继承自管理包类，所以我可以覆盖模板：
<?php
namespace Some\SiteBundle;
use Symfony\Component\HttpKernel\Bundle\Bundle;
class SomeSiteBundle extends Bundle
{
public function getParent()
{
return 'SonataAdminBundle';
}
}
在SomeSiteBundle/resources/views/CRUD/base_edit.html.twig中，我稍微修改了模板，以便让用户看到当前设置的图片：
<div class="sonata-ba-collapsed-fields">
{% for field_name in form_group.fields %}
{% if admin.formfielddescriptions[field_name] is defined %}
{% if field_name == 'fileName' %}
<h5 style="margin-left: 40px">Obecny obrazek:</h5>
{% if object.documents[0] is defined %}
<img style="margin: 0 0 0 40px; border: 1px dotted #ccc" src="{{ asset(object.documents[0].webPath) }}" />
{% else %}
<div style="margin-left: 40px">brak</div>
{% endif %}
<hr><h5 style="margin-left: 40px">Wczytaj nowy:</h5>
{% endif %}
{{ form_row(form[field_name])}}
{% endif %}
{% endfor %}
</div>
目前我在每篇新闻中只使用一张图片（“特色图片”），但这也有点过度，因为我正在使用带有jbimages插件的tinyMCE，所以我可以将图片放入新闻正文中。要使jbimages插件正常工作，您必须设置一些tinyMCE选项：
------ 这部分涉及tinymce、tinymce捆绑包和tinymce插件： ---------
$config['img_path'] = '/web/uploads/documents'; （或适合您的任何其他路径）在web/bundles/stfalcontinymce/vendor/tiny_mce/plugins/jbimages/config.php中。（当然，您需要首先安装stfalcon tinymce bundle）。然后，我编辑了一下web/bundles/stfalcontinymce/js/init.jquery.js，以允许从config.yml读取更多选项：
themeOptions.script_url = options.jquery_script_url;
//mine:
themeOptions.convert_urls = options.convert_urls;
themeOptions.relative_urls = options.relative_urls;
themeOptions.remove_script_host = options.remove_script_host;
themeOptions.document_base_url = options.document_base_url;
最后，在config.yml文件中：
[...]
stfalcon_tinymce:
include_jquery: true
tinymce_jquery: true
textarea_class: "tinymce"
relative_urls : false
convert_urls : false
remove_script_host : false
document_base_url : "http://somesite.home.pl/web/"
theme:
[...]
这就是所有的内容了，尽我所知是这样的。希望这会有所帮助；-)
