如何使用SonataAdmin將隱藏為實體的字段制成表單？

Question

我需要將實體字段添加為隱藏在我的表單中在具有奏鳴曲的管理表單中，我具有：

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'))

}

實際上，輸入中沒有值（請參閱檢查圖像）

知道它是實體類型，如何使driverNight字段隱藏？

Answer 1

您可以使用此處詳細介紹的數據轉換器 ： 數據轉換器

我建議您創建一個轉換器類，將視圖層中的entity轉換為int並在模型層中將其從int為entity ，並在配置表單中使用addModelTransformer方法。

1. 創建模型Transformer類，該類實現Symfony\\Component\\Form\\DataTransformerInterface並包含2個方法transform和reverseTransform 。 可以通過傳遞2個參數來構造該類：實體管理器和將轉換為int的用戶實體對象。

。

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調用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'));//.....
}
