Get auto generated ID right after flush() Symfony3 - php

Question

I have a Project entity and when creating a new project I need to be able to upload files. For this reason I have created Files entity which saves the path and projectID. My problem is that I don't know how to retrieve it after creating it. Here is what I am trying to do
$projectService->createProject($project,$user,$isWithoutTerm,self::NO_TERM_DEFAULT_VALUE);
$filesService = $this->get('app.service.files_service');
foreach ($managerFiles as $managerFile){
$fileName = $filesService->uploadFileAndReturnName($managerFile);
$filesService->createFile($fileName,$project->getId(),$user);
}
Currently my $project doesn't have ID which means that I cant create a new file. I heard that I could use $em->retrieve(object), but the actual flushing is not done in the controller. If i try to use it in my createProject function and return it for some reason I can't. PHPStorm says that it is a void function. Here is the code in createProject
$project->setFromUser($user->getFullName());
$project->setDepartment($user->getDepartment());
$project->setIsOver(false);
$project->setDate(new \DateTime());
if($isWithoutTerm){
$project->setTerm(\DateTime::createFromFormat('Y-m-d', $noTermDefaultValue));
}
$this->entityManager->persist($project);
$this->entityManager->flush();
Is there a way to retrieve the projectID after flushing and being able to use it in my controller?

Answer 1

It could be a race condition where the $project is not available yet and so the service cannot load it and thus getId() fails.
First, create your project entity:
//build your $project
$this->entityManager->flush();
Second, send this $project to your "service"
$projectService->createProject($project,$user,$isWithoutTerm,self::NO_TERM_DEFAULT_VALUE);
$filesService = $this->get('app.service.files_service');
foreach ($managerFiles as $managerFile){
$fileName = $filesService->uploadFileAndReturnName($managerFile);
$filesService->createFile($fileName,$project->getId(),$user);
}
More specifically if you wrap this in a try/catch you can identify exactly what is happening:
try {
$project = new Project();
//build project
$this->entityManager->flush();
//load $projectService..
$projectService->createProject($project,$user,$isWithoutTerm,self::NO_TERM_DEFAULT_VALUE);
$filesService = $this->get('app.service.files_service');
foreach ($managerFiles as $managerFile){
$fileName = $filesService->uploadFileAndReturnName($managerFile);
$filesService->createFile($fileName,$project->getId(),$user);
}
}
catch(\Exception $e) {
//$e->getMessage() will tell you if you're good to go, or if there
//is actually an issue
}
However, it could also be as simple as PHPStorm not being able to introspect your getId() method and thus doesn't understand it. OR getId() is not actually returning the id.

Upgrading the Symfony from 3.2 and 3.3 fixed the issue. I don't think it was due to the version itself, but rather removing depricated stuff and changing a lot of things and something fixed it.
