我有两个与实体规范具有多对多单向关系的实体（元产品和选项）。
Metaproduct和Option之间的关系是一对多的。
Metaproduct的Fieldsets和Forms的代码如下：
MetaproductFieldset.php
namespace Bundle\Fieldset;
class MetaproductFieldset extends EntityUsingFieldset implements InputFilterProviderInterface{
...
public function __construct(ObjectManager $objectManager)
{
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'options',
'options' => array(
'label' => 'Options',
'count' => 1,
'allow_add' => true,
'allow_remove' => true,
'should_create_template' => true,
'target_element' => new OptionFieldset($objectManager),
),
'attributes' => array(
'id' => 'options',
),
));
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'specifications',
'options' => array(
'label' => 'Specifications',
'count' => 1,
'allow_add' => true,
'allow_remove' => true,
'should_create_template' => true,
'target_element' => new SpecificationFieldset($objectManager),
),
'attributes' => array(
'id' => 'specifications',
),
));
OptionFieldset.php
namespace Bundle\Fieldset;
class OptionFieldset extends EntityUsingFieldset implements InputFilterProviderInterface{
public function __construct(ObjectManager $objectManager)
{
$this->setObjectManager($objectManager);
parent::__construct('option');
$this->setHydrator(new DoctrineHydrator($objectManager))->setObject(new \Bundle\Entity\Option());
$this->add(array(
'type' => 'Zend\Form\Element\Collection',
'name' => 'specifications',
'options' => array(
'label' => 'Specifications',
'count' => 1,
'allow_add' => true,
'allow_remove' => true,
'should_create_template' => true,
'target_element' => new SpecificationFieldset($objectManager),
),
'attributes' => array(
'id' => 'specifications',
),
));
SpecificationFieldset.php
namespace Bundle\Fieldset;
use Doctrine\Common\Persistence\ObjectManager;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use Zend\InputFilter\InputFilterProviderInterface;
class SpecificationFieldset extends EntityUsingFieldset implements InputFilterProviderInterface{
public function __construct(ObjectManager $objectManager)
{
$this->setObjectManager($objectManager);
parent::__construct('specification');
$this->setHydrator(new DoctrineHydrator($objectManager))->setObject(new \Bundle\Entity\Specification());
$this->add(array(
'type' => 'Zend\Form\Element\Hidden',
'name' => 'id'
));
$this->add(array(
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'name' => 'label',
'options' => array(
'label' => 'Label',
'object_manager' => $objectManager,
'target_class' => 'Bundle\Entity\Label',
'property' => 'value',
'empty_option' => '--- please choose ---'
),
));
$this->add(array(
'type' => 'Zend\Form\Element\Text',
'name' => 'value',
'options' => array(
'label' => 'Value'
)
));
}
Metaproduct.php
namespace Bundle\Form;
...
class Metaproduct extends Form {
public function __construct(ObjectManager $objectManager){
parent::__construct('metaproduct-form');
$this->setHydrator(new DoctrineHydrator($objectManager));
$mpFieldset = new MetaproductFieldset($objectManager);
$mpFieldset->setUseAsBaseFieldset(true);
...
但是当我尝试在该表单上打印绑定对象时，会抛出以下Expect：
