The document summarizes tips and tricks discussed at a meetup for PHP developers in Poznan, Poland. It covers accessing request parameters in Symfony controllers, naming strategies in Doctrine, using the app.user variable and Twig, configuring Swiftmailer for email delivery, automatically testing services, ParamConverters, DI/IoC bundles like JMSDiExtraBundle, JavaScript translation bundles, and AngularJS integration.

Symfony
tips & tricks

3. Accessing
request
parameters

4. /**
* @param Request $request
*
* @return JsonResponse
*/
public function getCandidateVisitAction(Request $request)
{
$candidateId = (int) $request->get('id');
$candidates = $this->getDoctrine()
->getRepository('EspeoCommonBundle:CandidateVisit')
->getVisitStatistics($candidateId);
return new JsonResponse($candidates);
}

5. /**
* @param Request $request
*
* @return JsonResponse
*/
public function getCandidateVisitAction(Request $request)
{
$candidateId = $request->query->getInt('id');
$candidates = $this->getDoctrine()
->getRepository('EspeoCommonBundle:CandidateVisit')
->getVisitStatistics($candidateId);
return new JsonResponse($candidates);
}

6. Naming
strategies

7. /**
* CandidateVisit.
*
* @ORMTable(name="candidate_visit")
* @ORMEntity(repositoryClass="EspeoCommonBundleEntity
RepositoryCandidateVisitRepository")
*/
class CandidateVisit
{
/**
* @var DateTime
*
* @ORMColumn(name="date_visit", type="datetime")
*/
private $dateVisit;
}

8. # app/config/config.yml
doctrine:
dbal:
(...)
orm:
naming_strategy: doctrine.orm.naming_strategy.underscore

9. <?php
namespace DoctrineORMMapping;
interface NamingStrategy
{
function classToTableName($className);
function propertyToColumnName($propertyName, $className = null);
function referenceColumnName();
function joinColumnName($propertyName);
function joinTableName($sourceEntity, $targetEntity, $propertyName);
function joinKeyColumnName($entityName, $referencedColumnName = null);
}

10. Twig &
app.user

11. {% if app.user and is_granted('ROLE_ADMIN') %}
...
{% endif %}

12. Email
delivery
whitelist

13. # Swiftmailer Configuration
swiftmailer:
transport: "%mailer_transport%"
host: "%mailer_host%"
username: "%mailer_user%"
password: "%mailer_password%"
spool:
type: file
path: "%kernel.root_dir%/spool"

14. # app/config/config_dev.yml
swiftmailer:
delivery_address: dev@example.com
delivery_whitelist:
# all email addresses matching these regexes will be delivered
# like normal, as well as being sent to dev@example.com
- '/@specialdomain.com$/'
- '/^admin@mydomain.com$/'

15. Automatic
"smoke testing"
for services

16. public function testContainerServices()
{
$client = static::createClient();
foreach ($client->getContainer()->getServiceIds() as $serviceId) {
$service = $client->getContainer()->get($serviceId);
$this->assertNotNull($service);
}
}

17. public function testContainerServices()
{
$client = static::createClient();
foreach ($client->getContainer()->getServiceIds() as $serviceId) {
try {
$startedAt = microtime(true);
$service = $client->getContainer()->get($serviceId);
$elapsed = (microtime(true) - $startedAt) * 1000;
$this->assertLessThan(50, $elapsed);
} catch(InactiveScopeException $e) {
}
}
}

18. symfony.com/doc/current/bundles/SensioFrameworkExtraBundle/annotations/converters.html
ParamConverter

19. use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SensioBundleFrameworkExtraBundleConfigurationParamConverter;
/**
* @Route("/blog/{id}")
* @ParamConverter("post", class="SensioBlogBundle:Post")
*/
public function showAction(Post $post)
{
}

20. use SensioBundleFrameworkExtraBundleConfigurationRoute;
use SensioBundleFrameworkExtraBundleConfigurationParamConverter;
/**
* @Route("/blog/{id}")
* @ParamConverter("post", class="SensioBlogBundle:Post", options=
{"entity_manager" = "foo"})
*/
public function showAction(Post $post)
{
}

21. Bundle

22. http://jmsyst.com/bundles/JMSDiExtraBundle
JMSDiExtraBundle

23. // composer.json
{
// ...
require: {
// ...
"jms/di-extra-bundle": "dev-master"
}
}

24. #app/AppKernel.php
$bundles = array(
// ...
new JMSDiExtraBundleJMSDiExtraBundle($this),
new JMSAopBundleJMSAopBundle(),
// ...
);

25. #app/config/config.yml
jms_di_extra:
locations:
all_bundles: false
bundles: [FooBundle, AcmeBlogBundle]
directories: ["%kernel.root_dir%/../src"]

26. <?php
namespace EspeoCandidateBundleController;
use EspeoCandidateBundleServiceCalendarEventProvider;
use EspeoCommonBundleControllerController;
use EspeoCommonBundleEntityRepositoryCitiesRepository;
use JMSDiExtraBundleAnnotation as DI;
use SymfonyComponentSecurityCoreAuthenticationTokenStorageTokenStorage;
use SymfonyComponentTranslationTranslatorInterface;
class CalendarApiController extends Controller
{
/**
* @var CalendarEventProvider
* @DIInject("espeo_candidate.calendar_event_provider")
*/
private $calendarEventProvider;
/**
* @var TokenStorage
* @DIInject("security.token_storage")
*/
private $tokenStorage;
/**
* @var CitiesRepository
* @DIInject("espeo_common.cities_repository")
*/
private $citiesRepository;
}

27. <?php
class CalendarApiController extends Controller
{
/**
* @var CalendarEventProvider
* @DIInject("espeo_candidate.calendar_event_provider")
*/
private $calendarEventProvider;
/**
* @var TokenStorage
* @DIInject("security.token_storage")
*/
private $tokenStorage;
/**
* @var CityRepository
* @DIInject("espeo_common.city_repository")
*/
private $cityRepository;
}

28. private function getCoolCities()
{
$cities = $this->cityRepository->getSosnowiecAndRadom();
return $cities;
}

29. use JMSDiExtraBundleAnnotation as DI;
class Controller
{
private $em;
private $session;
/**
* @DIInjectParams({
* "em" = @DIInject("doctrine.orm.entity_manager"),
* "session" = @DIInject("session")
* })
*/
public function __construct($em, $session)
{
$this->em = $em;
$this->session = $session;
}
}
