Doctrine. Cache. Entity relations - symfony

Question

I have two Entities Company and Storage with One-To-Many Bidirectional relationship. Entities and their relations are cached (doctrine second level cache). The issue is that, when i create a new Storage entity, Company storages collection doesn't have this new entity until I clear the cache manually.
AppBundle\Entity\Main\Company:
type: entity
table: main.company
cache:
usage: NONSTRICT_READ_WRITE
id:
id:
type: integer
nullable: false
id: true
generator:
strategy: IDENTITY
fields:
legalName:
type: string
nullable: false
length: 255
options:
fixed: false
column: legal_name
oneToMany:
storages:
targetEntity: AppBundle\Entity\Main\Storage
mappedBy: company
cascade: ["all"]
orphanRemoval: true
cache:
usage: NONSTRICT_READ_WRITE
AppBundle\Entity\Main\Storage:
type: entity
table: main.storage
cache:
usage: NONSTRICT_READ_WRITE
id:
id:
type: integer
nullable: false
options:
unsigned: false
id: true
generator:
strategy: IDENTITY
fields:
storageName:
type: string
nullable: true
length: 255
options:
fixed: false
column: storage_name
manyToOne:
company:
targetEntity: AppBundle\Entity\Main\Company
cascade: ["all"]
fetch: LAZY
mappedBy: null
inversedBy: storages
joinColumns:
company_id:
referencedColumnName: id
orphanRemoval: false
cache:
usage: NONSTRICT_READ_WRITE
This is action where Storage is created. There is nothing unusual.
public function addAction(Request $request)
{
$form = $this->createForm(StorageAddType::class, null);
$form->handleRequest($request);
if (!$form->isSubmitted()) {
throw new \RuntimeException('Некорректный запрос');
}
if (!$form->isValid()) {
throw new \Symfony\Component\Validator\Exception\ValidatorException((string)$form->getErrors(true));
}
$doctrine = $this->getDoctrine();
/**
* #var Storage $storage
*/
$storage = $form->getData();
$manager = $doctrine->getManager();
$manager->persist($storage);
$manager->flush();
return $this->createAjaxDataResponse($this->createSuccessMessage('Storage successfully added'));
}
Such behavior is watched only when i try to create new Entity (Storage). Then on update/delete actions - Storages collection of Company are updated.

You are clearly wrong with persisting data. You try to persist unserialized object from form into uknown repository via manager.
Try this:
public function addAction(Request $request)
{
$form = $this->createForm(StorageAddType::class, null);
$form->handleRequest($request);
$em = $this->getDoctrine()->getManager();
if($form->isSubmitted() && $form->isValid())
{
$storage = new Storage();
$storage->setVal1($form->get('Val1'));
$storage->setVal2($form->get('Val2'));
$em->persist($storage);
$em->flush();
return $this->createAjaxDataResponse($this->createSuccessMessage('Storage successfully added'));
}
return $this->render('YOUR_TWIG_LAYOUT', [
'form' => $form->createView()
]);
}
You can also try to persist whole object, if form is seriaized properly by serializing data into entity. Write method like setValsFromForm($data) and serialize vars from $data form.
Then change these lines:
$storage->setVal1($form->get('Val1'));
$storage->setVal2($form->get('Val2'));
into
$storage->setValsFromForm($form->getData());
Also:
Exceptions and form validations should be handled by Form Validator in form class, not in controller. Exception is when you create form via formbuilderinterface in the controller, but you add logic there, not outside $form class.
