Symfony2 && mongodb simple reference - mongodb

Question

he guys,
i want to make a simple reference on mongodb documents using symfony2.
i have this two documents and want to store picture references into the requests document. it works for me, if i have only the picture ids in the requests document.
so i need the follow:
can everyone change the document files and make and extends the custum call to get all pictures as object from the requests (picture array)?
my original files:
Document Pictures:
<?php
namespace TestBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
/**
* #MongoDB\Document(repositoryClass="TestBundle\Repository\RequestsRepository")
*/
class Requests
{
/**
* #MongoDB\Id
*/
protected $id;
/**
* #MongoDB\String
*/
protected $title;
public function setId($id)
{
$this->id = $id;
}
public function getId()
{
return $this->id;
}
public function setTitle($title)
{
$this->title = $title;
}
public function getTitle()
{
return $this->title;
}
}
Document Pictures:
<?php
namespace TestBundle\Document;
use Doctrine\ODM\MongoDB\Mapping\Annotations as MongoDB;
/**
* #MongoDB\Document(repositoryClass="TestBundle\Repository\PicturesRepository")
*/
class Pictures
{
/**
* #MongoDB\Id
*/
protected $id;
/**
* #MongoDB\String
*/
protected $filename;
public function setId($id)
{
$this->id = $id;
}
public function getId()
{
return $this->id;
}
public function setFilename($filename)
{
$this->filename = $filename;
}
public function getTitle()
{
return $this->filename;
}
}
My Basic Calls:
$dm = $this->get('doctrine.odm.mongodb.document_manager');
$request = $dm->getRepository('TestBundle:Requests')->find($requestId);
To my tests:
i added in the requests document the follow:
/**
* #MongoDB\ReferenceMany(targetDocument="Pictures",cascade={"persist"},simple="true")
*/
protected $pictures = array();
public function setPictures($pictures)
{
$this->pictures[] = $pictures;
}
public function getPictures()
{
return $this->pictures;
}
and added pictures like this:
$dm = $this->get('doctrine.odm.mongodb.document_manager');
$photo = $dm->getRepository('TestBundle:Pictures')->find($photoId);
$dm1 = $this->get('doctrine.odm.mongodb.document_manager');
$request = $dm1->getRepository('TestBundle:Requests')->find($requestId);
$request->setPictures($photo);
$dm1->flush();
this works - but i cannot get the pictures by loading the document.
my code to load:
$dm1 = $this->get('doctrine.odm.mongodb.document_manager');
$request = $dm1->getRepository('TestBundle:Requests')->find($requestId);
$pictures = $request->getPictures();
foreach($pictures as $picture)
{
print $picture->getId();
}
THIS WILL NOT WORK. i become the follow error:
Fatal error: Doctrine\ODM\MongoDB\Proxy\ProxyFactory::getProxy():
Failed opening required
'.../app/cache/dev/doctrine/odm/mongodb/Proxies/_CG_TestBundleDocumentPictures.php'
(include_path='.:.../library:/usr/local/zend/share/pear') in

on line 100
thanks, jan

Answer 1

First off you only need to call doctrine one time in $dm your overloading your resources and thats bad practice. One function, one Doctrine call. Secondly, you need a $dm->persist($request) and then $dm->flush(). Create a OnetoOne between your Documents and then make $pictures an Doctrine Array Collection. Then set a picture like you tried, then make a smiple query and call $request->getPicture()->getId().

Ok i found the error:
In the deps file i have the following lines:
[doctrine-common]
git=http://github.com/doctrine/common.git
version=2.1.4
[doctrine-dbal]
git=http://github.com/doctrine/dbal.git
version=2.1.7
[doctrine]
git=http://github.com/doctrine/doctrine2.git
version=2.1.7
After updating them to:
[doctrine-common]
git=http://github.com/doctrine/common.git
version=2.2.1
[doctrine-dbal]
git=http://github.com/doctrine/dbal.git
version=2.2.1
[doctrine]
git=http://github.com/doctrine/doctrine2.git
version=2.2.1
And doing php bin/vendors update the references will work again
