我有以下模型，或者當你把它們稱爲實體時，我也有一個控制器，一切工作在這個動作中，但是當我檢查數據庫時沒有用戶。所以我很好奇，因爲我失蹤了。因此，讓我們從一開始就瞭解我有什麼：學說不保存我的實體？
bootstrap.php包含以下代碼等等。
...
/** ---------------------------------------------------------------- **/
// 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();
}
...
所以現在我們有教義建立它的時間來創建一個模型（實體）並設置哪些字段，不能爲空等等等等。
注意在這一點上，你應該知道我沒有使用Symfony以及它的組件在Doctrine之上。我正在使用Slim Framework。因此，如果有任何建議是使用symfony中的x或y，請確保它是一個組件。

return true;

上述模型是正確的，因爲據我所知，我的意思是，當我運行"vendor/bin/doctrine migrations:migrate"數據庫表是創建。
現在，這裏用到了什麼？它的一個作用下稱爲SignupController控制器使用稱爲createAction($params)
**createAction($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!');
$params->redirect('/signin');
}
現在你應該在正確的我展現成功的閃光燈和重定向你輸入的一切。 這個作品它重定向，它顯示一個flash消息。但它的：
getEntityManager()->flush();
getEntityManager()->persist($user);
我不認爲是工作。爲什麼？因爲在有問題的數據庫上執行select * from users時沒有記錄。
爲什麼？
實體框架是一個.NET特定的框架，而不是一個通用術語。 –
