最后是表格：
<?php

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class NeedsType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('firstname')
->add('lastname')
->add('trainingneedstart')
->add('readytowork')
->add('relatedproject')
->add('relatedactivity')
->add('relatedjob')
->add('relatedexperience')
->add('maintrainingplant')
// Ajout du formulaire imbriqué des trainings en collection
->add('trainings', 'collection', array('type' => new TrainingsType(),
'allow_add' => true,
'allow_delete' => true,
'by_reference' => false,
))
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Chris\BabelBundle\Entity\Needs'
));
}
public function getName()
{
return 'chris_babelbundle_needstype';
}
}
<?php
namespace Chris\BabelBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class TrainingsType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('trainingstart')
->add('trainingend')
->add('trainingplant')
->add('training')
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Chris\BabelBundle\Entity\Trainings'
));
}
public function getName()
{
return 'chris_babelbundle_trainingstype';
}
}
除了保存的培训不包含数据库中的需求ID之外，其中大部分都有效，因此，在编辑需求时，我无法检索到多次培训。
答案 0 :(得分：4)
最后，我在法国IRC的帮助下找到了解决方案：）
我只需像这样修改Needs实体：
/**
* Add trainings
*
* @param \Chris\BabelBundle\Entity\Trainings $trainings
* @return Needs
*/
public function addTraining(\Chris\BabelBundle\Entity\Trainings $trainings)
{
$this->trainings[] = $trainings;
$trainings->setTraining($this);
return $this;
}
