SonataMediaBundle - 如何上传图片？

Question

Probably should be titled: "SonataMediaBundle - where's the missing howto?".

I've made some admin backend with sonataAdminBundle and sonataDoctrineORMAdminBundle (and some other), most of the things worked as expected, but I left file upload and handling for later, because I thought "how hard that possibly can be?".

To make long story short - is there ANY documentation about simplest of things - ie having images attached to a post or entry, how to configure sonata admin class, how to display image thumbs in edit form, etc.?

First page of documentation ends with "you can visit your admin dashboard" as if I could expect some relevant changes there, maybe media manager up and running, or something. But this is not the case.

Next page deals with heplers briefly, and then another page with fairly complicated vimeo provider case study.

I've searched all over the web and best I could come up with, was upload field with ajax popup, and list of uploaded files.

In my admin class I've got:

protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
    ->with('general')
        ->add('title')
        ->add('body')
        ->add('categories')
        ->end()
    ->with('media')
        ->add('images', 'sonata_type_model')

in my News class:

/**
 * @ORM\ManyToMany(targetEntity="Application\Sonata\MediaBundle\Entity\Media")
 */
public $images; 

and all the yaml configs and routings are implemented.

The result is: Fatal error: Call to a member function add() on a non-object in [some-entity].php when trying to upload an image, and selectable list of image id's with "plus" sign (sonata_type_model field I guess).

I'm stuck. I was able to create media "manager" just in plain sf2 in an hour or two, but it was another project and rewriting current one to this pattern means starting "from scratch". So - what to do in order to make sonataMediaBundle together with sonataAdminBundle work as expected?

EDIT: here's what I did instead:

My news class (or any other which needs image upload):

<?php

namespace Some\SiteBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
use Symfony\Component\Validator\Constraints as Assert;


/**

 *

 */
class News
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;      


    //some stuff...

  /**
    * @var Document documents
     * @ORM\ManyToMany(targetEntity="Document", cascade={"persist", "remove", "delete"} )
     **/
    protected $documents;


    public function __construct()
  {
    $this->documents = new ArrayCollection();

  }

[...]

    /**
     * Add documents
     *
     * @param Festus\SiteBundle\Entity\Document $documents
     */
    public function addDocument(\Festus\SiteBundle\Entity\Document $document)
    {
        $this->documents[] = $document;
    }

    /**
     * set document
     *
     * @param Festus\SiteBundle\Entity\Document $documents
     */
    public function setDocument(\Festus\SiteBundle\Entity\Document $document)
    {
        foreach ($this->documents as $doc) {
            $this->documents->removeElement($doc);
        }
        $this->documents[] = $document;
    }

    /**

    public function getDocuments()
    {

    // setters, getters...

As You can see, most of it is copied from symfony2 tutorial.

Now, for the controller:

<?php

use Symfony\Component\HttpFoundation\Request;

My base bundle class extends admin bundle class, co I could overwrite templates:

<?php

namespace Some\SiteBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class SomeSiteBundle extends Bundle
{

    public function getParent()
    {
        return 'SonataAdminBundle';
    }

}

And in SomeSiteBundle/resources/views/CRUD/base_edit.html.twig I've changed template a little bit to let user see currently set picture:

<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>

Right now I'm using only one picture per news ("featured picture") and it's a bit overkill anyway, because I'm using tinyMCE with jbimages plugin, so I can put images into news body anyway. To make jbimages plugin work right You've got to set some tinyMCE options though:

------ this part deals with tinymce and tinymce bundle and tinymce plugin: ---------

$config['img_path'] = '/web/uploads/documents'; (or any other path that suits You) in web/bundles/stfalcontinymce/vendor/tiny_mce/plugins/jbimages/config.php . (You need to install stfalcon tinymce bundle first, of course). Then I edited a bit web/bundles/stfalcontinymce/js/init.jquery.js to allow more options from config.yml to be read:

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;

And finally in config.yml :

[...]
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:
[...]

And that's all, AFAIR. Hope this helps ;-)

Answer 1

Maybe you can find the answer to your question in the: /admin/sonata/media/media/create?provider=sonata.media.provider.image&context=default

I am interested to your other solution, please post code. Thanks

Answer 2

Considered the best practice of the imposition of file storage on a separate server. What would it send a file or a link to a file, you can use Symfony byundle https://packagist.org/packages/avtonom/media-storage-client-bundle

if($file instanceof UploadedFile){
    $this->get('avtonom.media_storage_client.manager')->sendFile($file, $clientName, $context);
}
