如何使用 SonataAdmin 创建一个隐藏在表单中的实体字段？

Question

我需要在我的表单中添加实体字段作为隐藏字段在带有奏鸣曲的管理表单中，我有：

protected function configureFormFields(FormMapper $formMapper)
    {    
        if ($this->getRoot()->getSubject()->getId()) {
            $formMapper
                ->add('driverNight', 'hidden', array(), array('admin_code' => 'cab.admin.driver'))
            ->add('monday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Monday', 'value' => '0'))
            ->add('tuesday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Tuesday', 'value' => '0'))
            ->add('wednesday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Wednesday', 'value' => '0'))
            ->add('thursday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Thursday', 'value' => '0'))
            ->add('friday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Friday', 'value' => '0'))
            ->add('saturday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Saturday', 'value' => '0'))
            ->add('sunday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Sunday', 'value' => '0'))

}

实际上，输入中没有值（参见检查图像）

如何隐藏 driverNight 字段，知道它是实体类型？

Answer 1

您可以使用此处详述的数据转换器：data transformer

我建议您创建一个转换器 class，它将视图层中的 entity 转换为 int，并从 int 反转为 entity在模型层中，并在配置表单中使用 addModelTransformer 方法。

创建模型 Transformer class，它实现 Symfony\Component\Form\DataTransformerInterface 并包含 2 个方法 transform 和 reverseTransform。这个 class 可以通过传递 2 个参数来构造：实体管理器和将转换为 int 的用户实体对象。

.

class DriverToIntTransformer implements DataTransformerInterface {
private $manager;
private $driver;

public function __construct(ObjectManager $manager, $oUser)
{
    $this->manager = $manager;
    $this->driver = $oUser;
}
public function transform($user)
{
    if (null === $user) {
        return $this->driver->getId();
    }
    return $user->getId();
}
public function reverseTransform($driverNumber)
{
    if (!$driverNumber) {
        return;
    }
    $oDriver = $this->manager
        ->getRepository('YourUserBundle:User')
        // query for the driver with this id
        ->find($driverNumber);
    if (null === $oDriver) {
        throw new TransformationFailedException(sprintf(
            'An user with number "%s" does not exist!',
            $driverNumber
        ));
    }
    return $oDriver;
}

2 调用转换方法：

if ($this->getRoot()->getSubject()->getId()) {
        $driver = $this->getRoot()->getSubject()->getId(); 
$em = $this->container->get('doctrine.orm.entity_manager');
        $oDriver = $em->getRepository('YourUserBundle:User')->find($driver);
        $formMapper
            ->add('driverNight', 'hidden', array(), array('admin_code' => 'cab.admin.driver'));
        $formBuilder = $formMapper->getFormBuilder();
        $formBuilder->get('driverNight')->addModelTransformer(new DriverToIntTransformer($em, $oDriver));



    $formMapper
        ->add('monday', 'checkbox', array('required' => false, "attr" => array('class' => 'checkbox-day'), 'label' => 'Monday', 'value' => '0'));//.....
}
