如何使用 SonataAdmin 将实体字段隐藏在表单中？

Question

我需要将实体字段添加为隐藏在我的表单中 在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（请参阅检查图像）

知道 driverNight 字段是实体类型，如何将其隐藏？

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类，将视图层中的entity 转换为int，并在模型层中从int 反转为entity，并在您的配置表单。

1. 创建实现Symfony\Component\Form\DataTransformerInterface并包含transform和reverseTransform两个方法的模型Transformer类。可以通过传递 2 个参数来构造此类：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transform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'));//.....
}
