Subformularios Symfony2

Question

Por lo tanto, estoy tratando de insertar un formulario en otro sin crear una clase para los formularios. Esto es lo que he conseguido

$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(); 

sin embargo, en la función getForm(), diciendo su

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

Alguien tiene alguna idea de cómo supone im a conseguir que esto funcione utilizando la materia quickloading?

heres 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")); 
}

Answer 1

terminó creando una interfaz para el subformulario y agregándolo como esto

$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(); 

si alguien puede encontrar una manera más fácil y sin la creación de interfaces, que me haga saber

Answer 2

Trate

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

Si pasa un objeto FormBuilder al método add sin especificar el nombre de la propiedad, se utiliza el nombre del objeto FormBuilder (que es 'form') como el nombre de la propiedad. No hay una propiedad llamada form en la entidad UserAlert.
