我有2个关于验证的问题。我在我的实体中使用了很多属性方法(getter)(更好的代码imho)。这是一个这样的实体:
class Spec2Events implements ValueAssignable
{
private $values;
/**
* @return \Doctrine\Common\Collections\Collection
*/
public function getValues()
{
return $this->values;
}
/**
* @return \Doctrine\Common\Collections\Collection
*/
public function getCauseOfDeathValues()
{
$codPms=array();
array_push($codPms,'Cause of death::Natural');
array_push($codPms,'Cause of death::Bycatch');
array_push($codPms,'Cause of death::Ship strike');
array_push($codPms,'Cause of death::Predation');
array_push($codPms,'Cause of death::Other');
array_push($codPms,'Cause of death::Unknown');
return $this->getValues()->filter(
function($entry) use ($codPms) {
return in_array($entry->getPmdSeqno()->getName(), $codPms);
}
);
}
}
在这种情况下,$ values是SpecimenValues(实现EntityValues)的集合。 ValueAssignables有一个EntityValues集合。
EntityValuesType类是实现EntityValues的任何类的表单。这个表格有一些文字或选择孩子。
EntityValuesType表单的调用方式如下:
$builder->add('causeOfDeathValues', 'collection', array('type' => new EntityValuesType($this->doctrine),
'options' => array('data_class' => 'AppBundle\Entity\SpecimenValues'),
'allow_delete' => true,
'delete_empty' => true
)); //in order to check if using a class getter as a property works (fails)
$builder->add('values', 'collection', array('type' => new EntityValuesType($this->doctrine),
'options' => array('data_class' => 'AppBundle\Entity\SpecimenValues'),
'allow_delete' => true,
'delete_empty' => true
)); //in order to check if using a class member as a property works (works)
SpecimenValues的Validation.yml如下所示:
AppBundle\Entity\SpecimenValues:
properties:
pmdSeqno:
- NotBlank: ~
- NotNull: ~
s2eScnSeqno:
- NotBlank: ~
- NotNull: ~
description:
- Length:
min: 0
max: 250
value:
- NotBlank: ~
- NotNull: ~
- Length:
min: 1
max: 50
valueFlag:
- Length:
min: 0
max: 50
控制器如下所示:
public function newAction()
{
$observation = $this->prepareObservation();
$form = $this->createForm(new ObservationsType($this->getDoctrine()), $observation);
return $this->render('AppBundle:Page:add-observations-specimens.html.twig', array(
'form' => $form->createView()
));
}
private function prepareObservation(){
$observation = new Observations();
$event = new EventStates();
$observation->setEseSeqno($event);
$s2e = new Spec2Events();
$event->setSpec2Events($s2e);
$this->instantiateSpecimenValues('Cause of death::Natural', $s2e, false);
$this->instantiateSpecimenValues('Cause of death::Bycatch', $s2e, false);
$this->instantiateSpecimenValues('Cause of death::Ship strike', $s2e, false);
$this->instantiateSpecimenValues('Cause of death::Predation', $s2e, false);
$this->instantiateSpecimenValues('Cause of death::Other', $s2e, false);
$this->instantiateSpecimenValues('Cause of death::Unknown', $s2e, false);
//...
return $observation;
}
private function instantiateSpecimenValues($pmName, &$s2e, $mustBeFlagged)
{
$em = $this->getDoctrine()->getManager();
$pm = $em->getRepository("AppBundle:ParameterMethods")->getParameterMethodByName($pmName);
$sv = new SpecimenValues();
$sv->setPmdSeqno($pm);
$sv->setS2eScnSeqno($s2e);
$sv->setValueFlagRequired($mustBeFlagged);
return $sv;
}
现在,我的问题是验证程序不会阻止空值(不会出现表单错误消息)。
如果我在FormEvents :: PRE_SET_DATA中以编程方式添加验证约束,如下所示:
$options2['constraints'] = array(new \Symfony\Component\Validator\Constraints\NotNull());
它可以工作,但忽略了放在.yml文件中的约束。是否有可能将这种“以编程方式”AND与validation.yml结合起来?在任何情况下,我都会写一个回调来添加.yml,所以我更喜欢validation.yml。
使用名称为'values'的表单子对应于纯类成员变量,它应该按原样运行:所有必需的空字段都会收到消息。所有其他验证工作正常。
有什么可以解决这个问题?我也可以使用'values'并使用twig来分割集合,但我更喜欢使用方法作为属性访问器。
谢谢!
答案 0 :(得分:0)
我只是通过创建getter和properties属性来解决这个问题。属性本身在setter中设置。这是必要的,否则永远不会调用验证器。
所以:
/**
* @var \Doctrine\Common\Collections\Collection
* @ORM\OneToMany(targetEntity="AppBundle\Entity\SpecimenValues", mappedBy="s2eScnSeqno")
*/
private $values;
private $causeOfDeathValues;
/**
* @param \Doctrine\Common\Collections\Collection $values
* @return Spec2Events
*/
public function setCauseOfDeathValues(\Doctrine\Common\Collections\Collection $values)
{
$this->causeOfDeathValues=$values;
$this->values= new \Doctrine\Common\Collections\ArrayCollection(
array_merge($this->getValues()->toArray(), $values->toArray())
);
return $this;
}
