教义不是在拯救我的实体吗？

Question

我有以下模型，或者你称之为实体，我还有一个控制器，在这个动作中一切正常，但是当我检查数据库时没有用户。所以我很好奇我错过了什么。那么让我们从头开始，看看我有什么：

bootstrap.php 包含以下代码等。

...
/** ---------------------------------------------------------------- **/
// Lets Setup Doctrine.
/** ---------------------------------------------------------------- **/
require_once 'vendor/autoload.php';

$loader = require 'vendor/autoload.php';
\Doctrine\Common\Annotations\AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

use Doctrine\ORM\Tools\Setup;
use Doctrine\ORM\EntityManager;

/**
 * Set up Doctrine.
 */
class DoctrineSetup {

    /**
     * @var array $paths - where the entities live.
     */
    protected $paths = array(APP_MODELS);

    /**
     * @var bool $isDevMode - Are we considered "in development."
     */
    protected $isDevMode = false;

    /**
     * @var array $dbParams - The database paramters.
     */
    protected $dbParams = null;

    /**
     * Constructor to set some core values.
     */
    public function __construct(){
        if (!file_exists('db_config.ini')) {
            throw new \Exception(
                'Missing db_config.ini. You can create this from the db_config_sample.ini'
            );
        }

        $this->dbParams = array(
            'driver' => 'pdo_mysql',
            'user' => parse_ini_file('db_config.ini')['DB_USER'],
            'password' => parse_ini_file('db_config.ini')['DB_PASSWORD'],
            'dbname' => parse_ini_file('db_config.ini')['DB_NAME']
        );
    }

    /**
     * Get the entity manager for use through out the app.
     *
     * @return EntityManager
     */
    public function getEntityManager() {
        $config = Setup::createAnnotationMetadataConfiguration($this->paths, $this->isDevMode, null, null, false);
        return EntityManager::create($this->dbParams, $config);
    }
}

/**
 * Function that can be called through out the app.
 *
 * @return EntityManager
 */
function getEntityManager() {
    $ds = new DoctrineSetup();
    return $ds->getEntityManager();
}

/**
 * Function that returns the conection to the database.
 */
function getConnection() {
    $ds = new DoctrineSetup();
    return $ds->getEntityManager()->getConnection();
}
...

现在我们已经有了学说，可以创建模型（实体）并设置哪些字段可以为空，哪些字段不能为空等等。

注意在这一点上，你应该知道我不是在使用 Symfony，而是它在 Doctrine 之上的组件。我正在使用 Slim 框架。因此，如果有任何建议是使用 symfony 中的 x 或 y，请确保它是一个组件。

        }
    }
}

上面的模型是正确的，据我所知，我的意思是当我运行"vendor/bin/doctrine migrations:migrate"创建了一个数据库tableis .

现在，这些都用在什么地方了？它在名为 SignupController 的控制器中用于名为 createAction($params)

的操作

**createAction($params)**

public static function createAction($params){
  $postParams = $params->request()->post();
  $flash = new Flash();

  if ($postParams['password'] !== $postParams['repassword']) {
    $flash->createFlash('error', 'Your passwords do not match.');
    self::$createEncryptedPostParams($postParams);
    $params->redirect('/signup/error');
  }

  $user = new User();

  $user->setFirstName($postParams['firstname'])
       ->setLastName($postParams['lastname'])
       ->setUserName($postParams['username'])
       ->setEmail($postParams['email'])
       ->setPassword($postParams['password'])
       ->setCreatedAtTimeStamp();

  $validator = Validator::createValidatorBuilder();
  $validator->enableAnnotationMapping();

  $errors = $validator->getValidator()->validate($user);

  if (count($errors) > 0) {
      foreach($errors as $error) {
        $flash->createFlash(
            $error->getPropertyPath() . 'error',
            $error->getMessage()
        );
    }

    self::createEncryptedPostParams($postParams);
    $params->redirect('/signup/error');
  }

  $anyEncryptedErors = self::getEncryptedPostParams();
  if ($anyEncryptedErors !== null) {
    $anyEncryptedErors->destroy('error');
  }

  getEntityManager()->flush();
  getEntityManager()->persist($user);

  $flash->createFlash('success', ' You have signed up successfully! Please sign in!');
  $params->redirect('/signin');
}

现在你应该正确输入所有内容，我会显示成功并重定向你。 这有效 它重定向，它显示一条闪现消息。但它是：

  getEntityManager()->flush();
  getEntityManager()->persist($user);

我认为这行不通。为什么？因为对有问题的数据库执行 select * from users 返回时没有任何记录。

为什么？

Answer 1

Flush语句应该在persist之后执行。所以代码应该是：

getEntityManager()->persist($user);
getEntityManager()->flush();

Answer 2

如果您有对象 ID，然后数据库没有显示它，您可能有一个 "START TRANSACTION"，然后您有一个插入，在此插入之后您将有一个 "COMMIT"。如果在您的坚持和提交之间出现任何错误，对象将不会存储在您的数据库中。检查您的 Symfony 请求分析器信息。您可以使用开发者工具找到它并检查您的回复。

Answer 3

我有一个类似的问题，我想我会 post 在这里。我正在创建一个实体并且一切都正确响应，但是当我检查数据库时没有创建任何记录。

只需将冲洗包裹在 try-catch 中并记录错误。

$this->em->persist($insectLifeCycle);
try {
    $this->em->flush();
} catch (\Exception $error) {
    $this->logger->debug($error);    
}

事实证明，其中一个属性超出了其字符数限制，数据库引发了错误。还发现我需要改进我的错误处理....

Answer 4

正如 Samiul Amin Shanto 所说：

getEntityManager()->persist($user);
getEntityManager()->flush();

将是正确的方法，因为持久化操作准备要存储在数据库中的数据并刷新“将所有更改刷新到数据库中。”
