Api platform add or update - api-platform.com

Question

Good afternoon I am adding data in via POST method in PLATFORM API can I make this method work like adding or updating data.
So that when the data is already there for the object, it will simply update the pinOrder field.
My input:
{
"chat": "/api/chats/01FVKRYXMMTHKJ2EZB02F4FZ3Z",
"pinOrder": 3
}

Answer 1

Insert or update (upsert) is not available in Api Platform. However, you can achieve this behavior with a custom (or decorated) Data Persister.
https://api-platform.com/docs/core/data-persisters/
In the persist method of the data persister you could manually check if an item matching your criteria does already exist and, if yes, update this one instead of persisting a new one.

Answer 2

You can use PRE_WRITE event. For exemple, an order item quantity.
public static function getSubscribedEvents(): array
{
return [
KernelEvents::VIEW => [
'updateExistingItemQuantity', EventPriorities::PRE_WRITE,
],
];
}
public function updateExistingItemQuantity(
ViewEvent $event
): void {
$item = $event->getControllerResult();
$method = $event->getRequest()->getMethod();
if (!$item instanceof MyItemObject || Request::METHOD_POST !== $method) {
return;
}
// find duplicateItem
if ($duplicateItem) {
$duplicateItem->setQuantity("UPDATED QUANTITY");
// save $duplicateItem
$event->setControllerResult($duplicateItem);
}
}
