Symfony2子表格

Question

所以，即时尝试嵌入一个窗体在另一个没有创建一个窗体的类。下面有什么Ive得到

$form = $this 
     ->buildForm('UserAlert', $alert) 
     ->add('Alert', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Alert', 'property' => 'name', 'required' => true)) 
     ->add('Site', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Site', 'property' => 'name', 'required' => false)) 
     ->add('Keyword', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Keyword', 'property' => 'name', 'required' => false)) 
     ->add('Variant', 'entity', array('class' => 'Blah\MgmtBundle\Entity\Variant', 'property' => 'name', 'required' => false)) 
     ->add('Name', 'text'); 


    $uac = $alert->getUserAlertConfig(); 
    $subform = $this 
     ->buildForm('UserAlertConfig', $uac) 
     ->add('EmailAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Email Alerts')) 
     ->add('EmailHours', 'text', array('required' => false, 'label' => 'Email Alert Hours')) 
     ->add('TextAlert', 'choice', array('choices' => array('1' => 'Yes', '0' => 'No'), 'required' => true, 'label' => 'Text Alerts')) 
     ->add('TextHours', 'text', array('required' => false, 'label' => 'Text Alert Hours')); 

    $form->add($subform); 
    $form = $form->getForm(); 

然而，在getForm()功能，它说

Neither property "form" nor method "getForm()" nor method "isForm()" exists in class "Blah\MgmtBundle\Entity\UserAlert" 

人有任何想法IM应该如何得到这个使用quickloading东西工作？

继承人buildForm

public function buildForm($model = '', $data) 
{ 
    if (empty($model)) { 
     throw new \Exception("Must define a model"); 
    } 
    return $this->get('form.factory')->createBuilder('form', $data, array('data_class' => "\\Blah\\MgmtBundle\\Entity\\$model")); 
}

结束了创建的子窗体的接口，并加入像这样

$form = $this 
     ->buildForm('UserAlert', $alert) 
     ->add('Alert', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Alert', 'property' => 'name', 'required' => true)) 
     ->add('Site', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Site', 'property' => 'name', 'required' => false)) 
     ->add('Keyword', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Keyword', 'property' => 'name', 'required' => false)) 
     ->add('Variant', 'entity', array('class' => 'Neokeo\MgmtBundle\Entity\Variant', 'property' => 'name', 'required' => false)) 
     ->add('Name', 'text'); 

    $uac = $alert->getUserAlertConfig(); 



    $subform = $this->buildForm('UserAlertConfig', $uac, new \Neokeo\MgmtBundle\Form\UserAlertConfig) 
     ->add('EmailAlert', 'choice', array('choices' => array('0' => 'No', '1' => 'Yes'), 'required' => true, 'label' => 'Email Alerts')) 
     ->add('TextAlert', 'choice', array('choices' => array('0' => 'No', '1' => 'Yes'), 'required' => true, 'label' => 'Text Alerts')); 

    $form->add($subform, '', array('label' => '')); 
    $form = $form->getForm(); 

如果任何人都可以找到一个更简单的方法，而无需创建界面，让我知道

尝试

$form->add('The name of the UserAlertConfig property in the UserAlert entity', $subform); 

如果传递一个FormBuilder对象add方法没有指定属性的名称时，它使用FormBuilder对象的名称（这是'form'）作为属性名称。 UserAlert实体中没有名为form的属性。
