我有以下模型，或者你称之为实体，我也有一个控制器，一切都在这个动作中，但是当我检查数据库时没有用户。所以我很好奇我所缺少的。因此，让我们从头开始，了解我所拥有的：
bootstrap.php 包含以下代码。
...
/** ---------------------------------------------------------------- **/
// 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();
}
...
现在我们已经将学说设置为创建模型（实体）的时间，并设置哪些字段可以是空白等等，等等。
注意此时，您应该知道我没有使用Symfony，而不是在Doctrine之上使用它的组件。我正在使用Slim Framework。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。

上述模型是正确的，据我所知，我的意思是当我运行"vendor/bin/doctrine migrations:migrate"数据库表 时创建。
现在，所有这些都用在了哪里？它在名为SignupController
createAction($params)的控制器中使用
**createAction($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!');
$params->redirect('/signin');
}
现在你应该正确输入所有内容我会显示成功并重定向你。 此工作重定向，显示一条Flash消息。但它的：
getEntityManager()->flush();
getEntityManager()->persist($user);
我认为这不起作用。为什么？因为在有问题的数据库上执行select * from users会返回没有记录。
为什么吗
答案 0 :(得分：4)
Flush语句应该在持久化后执行。所以代码应该是：
getEntityManager()->persist($user);
getEntityManager()->flush();
答案 1 :(得分：-1)
如果您有对象ID，然后数据库没有显示它，则可能有一个“ START TRANSACTION”，然后有您的插入，在此插入之后，您将有一个“ COMMIT”。如果在持久化和COMMIT之间出现任何错误，则对象将不会存储在数据库中。 检查您的Symfony请求分析器信息。 您可以使用开发人员工具找到它，然后检查您的响应。
答案 2 :(得分：-1)
我有一个类似的问题，以为我会在这里发布。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，尚未创建任何记录。
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，其中一个属性超出其字符数限制，并且数据库引发错误。还发现我需要改进我的错误处理。...
