Symfony2 форма проверки исчерпана память

Question

У меня есть сложная форма со множеством полей выбора объектов. Когда я не использую проверку, добавьте/отредактируйте в порядке. Но когда я включаю проверку формы в /config/validation.yml, я больше не могу добавлять/редактировать. Я проверил файлы журналов PHP и увидеть некоторые ошибки:

Как исправить эту ошибку? Спасибо за помощь.

У меня сложная форма

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
$builder 
->add('beds', 'choice', [ 
    'choices' => [ 
     '1' => '1',

    ], 
    'placeholder' => '', 
])

    'required' => false, 
])

->add('body') 
->add('password', 'repeated', [ 
    'type' => 'password', 
    'invalid_message' => 'The password fields must match.', 
    'options' => array('attr' => array('class' => 'password-field')),

    'expanded' => true, 
    'multiple' => true,

     return $repository->createQueryBuilder('a') 
      ->from('AppBundle:Amenity', 'amenity') 
      ->where('a.type = 1'); 
    } 
]); 

И я использую EventSubscriber, чтобы добавить поле динамически

$builder->addEventSubscriber(new AddDistrictFieldSubscriber()) 
    ->addEventSubscriber(new AddStreetFieldSubscriber()) 
    ->addEventSubscriber(new AddWardFieldSubscriber()) 
    ->addEventSubscriber(new AddProjectFieldSubscriber()); 

class AddDistrictFieldSubscriber implements EventSubscriberInterface 
{ 

    /**

    * 
    * The array keys are event names and the value can be:

    * * An array composed of the method name to call and the priority

    } 

    public function preSetData(FormEvent $event)

     ]); 
    } 
}

Базы данных таблицы: - Область: идентификатор - имя (70 записей) - район: id - province_id - prefix - name (700 записей) - улица: id - district_id - prefix - name (17000 записей) - ward: id - district_id - prefix - name (11000 записей) ... и еще несколько таблиц

Answer 1

После отладки каждого поля в форме, в конце концов я нашел проблему в построитель запросов в preSubmit()

$form->add('district', 'entity', [ 
    'class' => 'AppBundle:District', 
    'property' => 'name', 
    'placeholder' => '', 
    'query_builder' => function (EntityRepository $repository) use ($province) { 
     return $repository->createQueryBuilder('d') 
      ->from('AppBundle:District', 'district') 
      ->where('district.province = :province') 
      ->setParameter('province', $province); 
    } 
]); 

$form->add('street', 'entity', [ 
    'class' => 'AppBundle:Street', 
    'property' => 'name', 
    'placeholder' => '', 
    'query_builder' => function (EntityRepository $repository) use ($district) { 
     return $repository->createQueryBuilder('s') 
      ->from('AppBundle:Street', 'street') 
      ->where('street.district = :district') 
      ->setParameter('district', $district); 
    } 
]); 

Я использую разностный псевдоним, так учение получит все записи в каждой таблице -> исчерпана память. Так просто использовать один и тот же псевдоним или удалить из() в построитель запросов;)

$form->add('district', 'entity', [ 
    'class' => 'AppBundle:District', 
    'property' => 'name', 
    'placeholder' => '', 
    'query_builder' => function (EntityRepository $repository) use ($province) { 
     return $repository->createQueryBuilder('district') 
      ->where('district.province = :province') 
      ->setParameter('province', $province); 
    } 
]);
