在 Symfony 中持久化更新的对象

Question

我有一个 symfony 应用程序，我正在尝试使用 setter 更新数据库中的实体。但是，当我更新实体并调用 $this->em->flush() 时，实体不会持久化到数据库中。

这是我的服务：

<?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);
    }
}

这是我的测试：

<?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');
    }


}

testAddCredit() 测试通过（因为我检查的是同一个对象），但 testAddCreditByEmail 失败并出现以下错误：1) AppBundle\Tests\Service\MyServiceTest::testAddCreditByEmail Failed asserting that null matches expected 149.

我尝试过持久化实体，刷新实体（如：$this->em->flush($user)）都无济于事。请让我知道如何解决此问题。

Answer 1

我发现了问题。

在测试用例中，我只需要通过 $this->getEntityManager()->refresh($user)（在原始 $user 实体上）来刷新实体。谢谢！
