Doctrine persist entity with inverse relation not work - symfony

Question

I'm trying to save two entities linked. Product entity may have any or many entities ProviderRate. When I try to save the product entity, it tells me that ProviderRate related entity has not assigned one of their required fields. I need to save a product with no need to assign a ProviderRate.
The error message showing me is:
Entity of type AppBundle\Entity\ProviderRate is missing an assigned ID for field 'provider'.
The identifier generation strategy for this entity requires the ID field to be populated before EntityManager#persist() is called.
If you want automatically generated identifiers instead you need to adjust the metadata mapping accordingly.
My entitdades code is as follows:
Product Entity

The code to run on the controller is as follows:
public function ajaxNewProductAction() {
$request = $this->getRequest();
$product = new Products();
$form = $this->createForm(new ProductsType(), $product);
$form->handleRequest($request);
if ($request->getMethod() == 'POST') {
if ($form->isSubmitted() && $form->isValid()) { // Se procesa el formulario
$em = $this->getDoctrine()->getManager();
$providerId = $request->get('provider');
$productVals = $request->get('Products');
$currency = $em->getRepository('AppBundle:Currencies')->findOneByName("Euro");
$product->setCurrency($currency);
$product->setType($em->getRepository('AppBundle:ProductTypes')->findOneById(1));
$product->setIsactive(1);
$em->persist($product);
$em->flush();
$response['success'] = true;
$response['data'] = 0;
$response['providerId'] = $providerId;
}
else {
$response['success'] = false;
$response['cause'] = 'whatever';
}
return new JsonResponse($response);
}
return $this->render(':products/ajax:newProduct.html.twig', array("form" => $form->createView(), "edit" => false));
}

SOLVE:
I can solve it. The code of my entities thats ok. I change the controller function.
First I create the product object, set the providerRate to null and them persist it.
After I create the providerRate object and set the product object.
public function ajaxNewProductAction() {
$request = $this->getRequest();
$product = new Products();
$form = $this->createForm(new ProductsType(), $product);
$form->handleRequest($request);
if ($request->getMethod() == 'POST') {
if ($form->isSubmitted() && $form->isValid()) { // Se procesa el formulario
$em = $this->getDoctrine()->getManager();
$providerId = $request->get('provider');
$productVal = $request->get('Products');
$currency = $em->getRepository('AppBundle:Currencies')->findOneByName("Euro");
$product->setCurrency($currency);
$product->setType($em->getRepository('AppBundle:ProductTypes')->findOneById(1));
$product->setProviderRate(null);
$em->persist($product);
$em->flush();
$providerRate = new ProviderRate();
$providerRate->setProvider($em->getRepository('AppBundle:Providers')->findOneById($providerId));
$providerRate->setProduct($product);
$providerRate->setReference($productVal["providerRate"][1]["reference"]);
$providerRate->setName($productVal["name"]);
$providerRate->setDescription($productVal["description"]);
$providerRate->setAmountPerUnit(1);
$providerRate->setUnitPrice(0);
$providerRate->setDiscount(0);
$providerRate->setCurrency($currency);
$providerRate->setProduct($product);
$em->persist($providerRate);
$em->flush();
$response['success'] = true;
}
else {
$response['success'] = false;
$response['cause'] = 'Algo ocurrió';
}
return new JsonResponse($response);
}
return $this->render(':products/ajax:newProduct.html.twig', array("form" => $form->createView(), "edit" => false));
}
