Symfony的2嵌入表單

Question

我嵌入表單類型到另一種形式的類型，像這樣

$builder->add('parent', new \Company\Bundle\Form\UserObjects\AParentType); 

然而，當我嘗試和要求綁定到窗體

if($request->getMethod() == 'POST') { 
     $form->bindRequest($request); 
} 

我得到的錯誤

Catchable Fatal Error: Argument 1 passed to Company\Bundle\Entity\UserObjects\User::setParent() must be an instance of Company\Bundle\Entity\UserObjects\AParent, array given, called in /Volumes/Media/Symfony/vendor/symfony/src/Symfony/Component/Form/Util/PropertyPath.php on line 346 and defined in /Volumes/Media/Symfony/src/Company/Bundle/Entity/UserObjects/User.php line 771

好像形式使「AParent」對象作爲陣列而不是作爲一個實體。有任何想法嗎？

Answer 1

您尚未在您的AParentType表單中設置數據類。你是這樣做的：

public function getDefaultOptions(array $options) 
{ 
    return array(
     'data_class' => 'Project\MyBundle\Entity\AParent', 
    ); 
} 

爲symfony1.2的後續版本，你需要使用它代替：

use Symfony\Component\OptionsResolver\OptionsResolverInterface; 
//... 

public function setDefaultOptions(OptionsResolverInterface $resolver) 
{ 
    $resolver->setDefaults(array(
     'data_class' => 'Project\MyBundle\Entity\AParent', 
    )); 
} 

替換此：

->add('parent', new \Company\Bundle\Form\UserObjects\AParentType); 

有了這個：

->add('parent', new AParentType()); 

，因爲你已經包括贈送T他命名空間。

如果這是一個對一個，它是在你的表單模板，你這樣做：

{{ form_row(form.parent.zipCode) }} 

希望這應該工作。你的實體定義看起來不錯:-)
