Doctrine trying to persist Owner - php

Question

I've setup Doctrine and Symfony-forms independent of the Symfony Framework (as I don't need most of it).
The issue I'm having is, when trying to persist a new "Audit" which has an "Type" doctrine seems to want to persist the owning side of the relationship (Type).
For example as Audit may have a type of Vehicle Service.
// -- Model/Audit.php --
/**
* #var \Model\Type
*
* #ORM\ManyToOne(targetEntity="Model\Audit\Type", inversedBy="audits")
* #ORM\JoinColumn(name="type_id", referencedColumnName="id", nullable=true)
*/
private $type;
/**
* Set type
*
* #param \Model\Type $type
* #return Audit
*/
public function setType(\Model\Type $type)
{
$this->type = $type;
return $this;
}
And then in the inverse side:
/**
* #ORM\OneToMany(targetEntity="Model\Audit", mappedBy="type")
* #var type */
private $audits;
public function __construct() {
$this->audits = new \Doctrine\Common\Collections\ArrayCollection();
}
Persistance code looks as follows:
$data = $form->getData();
$entityManager->persist($data);
$entityManager->flush();
And finally the form class is:
class AuditType extends AbstractType {
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('name')
->add('type', 'entity', array(
'class' => "Model\Type"
));
}
All looks (to me at least) exactly the same as in all the documentations both Doctrine and Symfony sides but I'm getting this error:
A new entity was found through the relationship 'Model\Audit#type'
that was not configured to cascade persist operations for entity:
Vehicle Service. To solve this issue: Either explicitly call
EntityManager#persist() on this unknown entity or configure cascade
persist this association in the mapping for example
#ManyToOne(..,cascade={"persist"})."
Which is really frustrating as I don't want to persist the Type side, I just want to put (in most basic terms) the id of 3 into the type_id column. Yet Doctrine seems to think I want to create a new "Type" which I certainly do not. They already exist.
Using $entityManager->merge($audit); works in part, it allows the inital Audit and its FK's to be saved. However it caused any embedded forms to become ignored.

I think you need set
/**
* #ORM\OneToMany(targetEntity="Model\Audit", mappedBy="type")
* #var type
*/
private $audits;
public function __construct() {
$this->audits = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* #return ArrayCollection
*/
public function getAudits()
{
return $this->audits;
}
/**
* #param Audit $audit
*/
public function addAudits(Audit $audit)
{
$this->audits->add($audit);
$audit->setTyoe($this);
}
and in Type Audit.model
// -- Model/Audit.php --
/**
* #var \Model\Type
*
* #ORM\ManyToOne(targetEntity="Model\Audit\Type", inversedBy="audits")
* #ORM\JoinColumn(name="type_id", referencedColumnName="id", nullable=true)
*/
private $type;
/**
* Set type
*
* #param \Model\Type $type
* #return Audit
*/
public function setType(\Model\Type $type)
{
$this->type = $type;
}
