Persisting Updated Objects in Symfony - php

Question

I have a symfony application where I am attempting to update an entity in the database using a setter. However when I update the entity and call $this->em->flush() the entity is not persisted to the database.
Here is my service:
<?php
namespace AppBundle\Service;
use AppBundle\Exceptions\UserNotFoundException;
use Doctrine\ORM\EntityManager;
use AppBundle\Entity\User;
/**
* Class MyService
* #package AppBundle\Service
*/
class MyService extends BaseService {
/**
* #var EntityManager
*/
protected $em;
/**
* #var User
*/
protected $user;
/**
* MyService constructor.
* #param EntityManager $em
*/
public function __construct(EntityManager $em){
$this->em = $em;
}
/**
* See if a user email exists
* #param string $email
* #return bool
*/
public function checkEmailExists($email){
$this->user = $this->em
->getRepository('AppBundle:User')
->findOneBy(['email' => $email]);
return !(is_null($this->user));
}
/**
* add credit to a users account
* #param User $user
* #param integer $credit
*/
public function addCredit(User $user, $credit){
$user->addCredit($credit);
$this->em->flush();
}
/**
* add a credit to a users account
* #param $email
* #param $credit
*/
public function addCreditByEmail($email, $credit){
if(!($this->checkEmailExists($email))){
throw new UserNotFoundException(sprintf('User with email %s not found.', $email));
}
$this->addCredit($this->user, $credit);
}
}
Here is my test:
<?php
namespace AppBundle\Tests\Service;
use AppBundle\DataFixtures\ORM\PurchaseFixture;
use AppBundle\Entity\Vendor;
use AppBundle\Repository\OfferRepository;
use AppBundle\Tests\TestCase;
use AppBundle\Entity\Offer;
use AppBundle\DataFixtures\ORM\OfferFixture;
use AppBundle\DataFixtures\ORM\PaymentSystemFixture;
/**
* Class UserOfferServiceTest
* #package AppBundle\Tests\Service
*/
class MyServiceTest extends TestCase implements ServiceTestInterface
{
function __construct($name = null, array $data = [], $dataName = '')
{
$this->setFixtures([
'AppBundle\DataFixtures\ORM\CityFixture',
'AppBundle\DataFixtures\ORM\CountryFixture',
'AppBundle\DataFixtures\ORM\PaymentSystemFixture',
'AppBundle\DAtaFixtures\ORM\UserFixture',
]);
parent::__construct($name, $data, $dataName);
}
/**
* test the checkEmailExists() of app.vendor
*/
public function testCheckEmailExists(){
$myService = $this->getService();
$this->assertTrue($myService->checkEmailExists('user1#user1.com'));
$this->assertFalse($myService->checkEmailExists($this->fake()->safeEmail));
}
/**
* test the addCredit functionality
*/
public function testAddCredit(){
$myService = $this->getService();
$user = $this->getUser();
$this->assertEquals(0, $user->getCredit());
$toAdd = $this->fake()->numberBetween(1, 500);
$myService->addCredit($user, $toAdd);
$this->assertEquals($toAdd, $user->getCredit());
}
/**
* test the addCreditByEmail functionality
*/
public function testAddCreditByEmail(){
$myService = $this->getService();
$user = $this->getUser();
$email = $this->getUser()->getEmail();
$this->assertEquals(0, $user->getCredit());
$toAdd = $this->fake()->numberBetween(1, 500);
$myService->addCreditByEmail($email, $toAdd);
$updatedUser = $this->getEntityManager()
->getRepository('AppBundle:User')
->findOneBy(['email' => $email]);
$this->assertEquals($toAdd, $updatedUser->getCredit());
}
/**
* #return \AppBundle\Service\VendorService|object
*/
public function getService(){
$this->seedDatabase();
$this->client = $this->createClient();
return $this->client->getContainer()->get('app.admin_kiosk');
}
}
The testAddCredit() test passes (because I'm checking the same object), but the testAddCreditByEmail fails with the following error: 1) AppBundle\Tests\Service\MyServiceTest::testAddCreditByEmail
Failed asserting that null matches expected 149.
I've tried persisting the entity, flushing the entity (like: $this->em->flush($user)) all to no avail. Please let me know how I can fix this.

Answer 1

I found the issue.
In the test case I just had to refresh the entity by doing $this->getEntityManager()->refresh($user) (on the original $user entity). Thanks!
