Php Symfony 2嵌入式表单

我将一个表单类型嵌入到另一个表单类型中，如下所示

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

但是，当我尝试将请求绑定到表单时

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

我得到了错误

可捕获的致命错误：传递给Company\Bundle\Entity\UserObjects\User:：setParent（）的参数1必须是Company\Bundle\Entity\UserObjects\AParent的实例，数组给定，在第346行的/Volumes/Media/Symfony/vendor/Symfony/src/Symfony/Component/Form/Util/PropertyPath.php中调用，并在第771行的/Volumes/Media/Symfony/src/Company/Bundle/Entity/UserObjects/User.php中定义

表单似乎将“AParent”对象作为数组而不是实体传递。有什么想法吗

您尚未在AParentType表单中设置数据类。你是这样做的：

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

对于Symfony的更高版本，您需要使用以下选项：

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

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

替换此项：

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

为此：

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

因为您已经包含了名称空间

如果在表单模板中是一对一的，您可以：

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

希望这能奏效。您的实体定义看起来不错：-）
在您的第一个代码段中，类名后面的括号不是必须的吗？如果您能看到更多的代码，这也会很有帮助。这并不能告诉我们太多。@greg0ire我不这么认为，因为表单在页面上构建和显示得很好，但当表单发布并绑定到用户对象时，就是发生此错误的时候。@Jamie您还想看到什么，实际上没有那么多，我现在也不在计算机旁处理代码。您的实体定义和表单类。看起来关系有点问题，这很有效！非常感谢你！真不敢相信我竟然忘了那个方法，它现在有这么多意义！三年多后遇到这个问题哈!！最初的解决方案无效，但将
setDefaultOptions
与
选项resolvernterface
配合使用效果很好。我已将其添加到您的解决方案中。
->add('parent', new \Company\Bundle\Form\UserObjects\AParentType);

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

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