Doctrine isn't saving my entities? - php

Question

I have the following model, or as you call them entity, and I also have a controller, everything works in this action, but when I check the database there is no user. So I am curious as what I am missing. So lets start at the beginning as to what I have:
bootstrap.php contains the following code, among other things.
...
/** ---------------------------------------------------------------- **/
// 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();
}
...
So now that we have doctrine set up its time to create a model (entity) and set which fields can and cannot be blank and so on and so forth.
Note At this point, you should know that I am not using Symfony other then its components on top of Doctrine. I am using Slim Framework. So if any suggestion is to use x or y from symfony, please make sure its a component.

The above model is correct, as far as I know, I mean when I run "vendor/bin/doctrine migrations:migrate" a database table is created.
Now, where is all this used? it's used in a controller called SignupController under an action called 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!');
$params->redirect('/signin');
}
Now should you enter everything in correctly I show a flash of success and redirect you. THIS WORKS it redirects, it shows a flash message. But its the:
getEntityManager()->flush();
getEntityManager()->persist($user);
That I don't think is working. Why? Because doing a select * from users on the database in question comes back with no records.
Why?

Answer 1

Flush statement should be execute after persist. So Code should be:
getEntityManager()->persist($user);
getEntityManager()->flush();

Answer 2

I had a similar issue and thought I would post it here. I was creating an entity and everything was responding correctly, but when I checked the database no record had been created.
Just wrapped the flush in a try-catch and logged the error.
$this->em->persist($insectLifeCycle);
try {
$this->em->flush();
} catch (\Exception $error) {
$this->logger->debug($error);
}
It turns out that one of properties was exceeding its character limit and the database was throwing an error. Also found out I need to improve my error handling....

Answer 3

As Samiul Amin Shanto said:
getEntityManager()->persist($user);
getEntityManager()->flush();
will be correct way, because persist action prepare the data to be stored in DB and flush "Flushes all changes to now to the database."

Answer 4

If you have the object id and then, the database is not showing it, you might have a "START TRANSACTION" and then you have your insert, after this insert you will have a "COMMIT". If any error appears between your persist and the COMMIT, object won't be stored in your database.
Check your Symfony request profiler information.
You can find it using the developer tool and checking your response for it.
