JMS serializer ignores doctrine entity id - php

Question

I tried map data from a given array to an object with the jms serializer (in a unit test) to test a doctrine entity:
Given is a simple entity class:
/**
* CashPosition
*/
class CashPosition
{
/**
* #var integer
*/
protected $cashPositionId;
/**
* #var \DateTime
*/
protected $date;
/**
* #var float
*/
protected $value;
/**
* Get cashPositionId
*
* #return integer
*/
public function getCashPositionId()
{
return $this->cashPositionId;
}
/**
* Set date
*
* #param \DateTime $date
*
* #return $this
*/
public function setDate($date)
{
$this->date = $date;
return $this;
}
/**
* Get date
*
* #return \DateTime
*/
public function getDate()
{
return $this->date;
}
/**
* Set value
*
* #param string $value
*
* #return $this
*/
public function setValue($value)
{
$this->value = $value;
return $this;
}
/**
* Get value
*
* #return float
*/
public function getValue()
{
return $this->value;
}
}
I defined the serialization under Resources\config\serializer\Entity.CashPosition.yml
MyBundle\Entity\CashPosition:
exclusion_policy: ALL
access_type: public_method
properties:
cashPositionId:
exclude: false
expose: true
type: integer
access_type: property
date:
exclude: false
expose: true
type: DateTime<'Y-m-d'>
value:
exclude: false
expose: true
type: float
And tried to cover this with a serialization test:
public function testSerialization()
{
$data = [
'cashPositionId' => 1,
'date' => date('Y-m-d'),
'value' => 1.0,
];
/* #var $serializer Serializer */
$serializer = $this->container->get('serializer');
$cashPosition = $serializer->fromArray($data, CashPosition::class);
$this->assertInstanceOf(CashPosition::class, $cashPosition);
$this->assertEquals($data, $serializer->toArray($cashPosition));
}
But the test fails since the fromArray method does not set the cashPositionId. I tried some different configurations with the access type but had no luck. I'm not sure what's the problem here.
I'm using the following version of jms serializer:
jms/metadata 1.6.0 Class/method/property metadata management in PHP
jms/parser-lib 1.0.0 A library for easily creating recursive-descent parsers.
jms/serializer 1.6.2 Library for (de-)serializing data of any complexity; supports XML, JSON, and YAML.
jms/serializer-bundle 1.4.0 Allows you to easily serialize, and deserialize data of any complexity

Hello i think you miss the serialized_name property for cashPositionId, by default jms will translate properties from camel case to snake case.
