With doctrine ODM, can I embed many subdocuments in a main document? - php

Question

I try to save this JSON:
{
"vendorId": "vendor-fc162cdffd73",
"company": {
"companyId": "bcos1.company.1806cf97-a756-4fbf-9081-fc162cdffd73",
"companyVersion": 1,
"companyName": "Delivery Inc.",
"address": {
"streetAddress": "300 Boren Ave",
"city": "Seattle",
"region": "US-WA",
"country": "US",
"postalCode": "98109",
"storeName": "Seattle Store",
"coordinates": {
"latitude": "45.992820",
"longitude": "45.992820"
}
},
"emailAddress": "johndoe#amazon.com",
"phoneNumber": "1234567890",
"websiteUrl": "delivery.com",
"creationDate": "2022-03-06T21:00:52.222Z"
},
"creationDate": "2022-04-06T21:00:52.222Z"
}
Company is a subdocument this has address and address has coordinates subdocument.
When I try to save with Hydratation, see example:
https://www.doctrine-project.org/projects/doctrine-laminas-hydrator/en/3.0/basic-usage.html#example-4-embedded-entities
I got this error:
1) AppTest\Services\AccountsServiceTest::testNewAccount with data set #0 (array('{"companyId":"bcos1.com...222Z"}', '', ''))
array_flip(): Can only flip STRING and INTEGER values!

$identifiers = array_intersect_key(

Answer 1

What you're trying to do is perfectly fine from ODM's perspective - you can have as many embeddables deep as you want. Unless there is something fishy going on in your Address or Coordinates embedded documents I would expect a bug in the laminas-hydrator package. The fact that ORM does not allow nested embeddables makes this scenario more likely. Best would be to try creating a failing test case and send a pull request with it.
In the meantime you can leverage ODM's hydrator:
$hydrator = $this->dm->getHydratorFactory()->getHydratorFor(Account::class);
$hydrator->hydrate(new Account(), $data, [Query::HINT_READ_ONLY => true]);
Please note the Query::HINT_READ_ONLY passed as a 3rd argument to hydrate. With this hint ODM will not mark hydrated objects as managed which is what you need for later insertion. Hydrated EmbedOne objects should be good to go without the hint, but EmbedMany may not work correctly without it. Please see https://github.com/doctrine/mongodb-odm/issues/1377 and https://github.com/doctrine/mongodb-odm/pull/1403 for more details about said hint.

Thank you #malarzm. I do this:
$coordinates = new Coordinates();
$hydrator->hydrate($data['company']['address']['coordinates'], $coordinates);
unset($data['company']['address']['coordinates']);
$address = new Address();
$hydrator->hydrate($data['company']['address'], $address);
unset($data['company']['address']);
$company = new Company();
$hydrator->hydrate($data['company'], $company);
unset($data['company']);
$account = new Account();
$hydrator->hydrate($data, $account);
$address->setCoordinates($coordinates);
$company->setAddress($address);
$account->setCompany($company);
I realized unset() for each embed sud-document and finally I set each sub-document with set method of my entity.
It was the only way to do work fine.
