如何在Symfony2中设置字段值集合类型

Question

// - 形式timesheettype ---它不是实体类

class TimeSheetType extends AbstractType { 

     public function buildForm(FormBuilder $builder, array $options) { 
      $builder-> 
        add('dailyTimeSheet', 'collection', array('type' => new DailyType(), 'allow_add' => true, 'allow_delete' => true, 'prototype' => true,)) 
        ->add('comment','textarea'); 
     } 

     public function getName() { 
      return 'TimeSheetDaily'; 
     } 

    } 

// --- DailyType - 没有实体对于这种类型的

class DailyType extends AbstractType { 


    public function buildForm(FormBuilder $builder, array $options) { 


     $builder->add('project','entity',array('class'=> 'Parabola\EntityBundle\Entity\Project','property'=>'name')) 
       ->add('projectTask', 'entity', array('class'=> 'Parabola\EntityBundle\Entity\ProjectTask','property'=>'name')) 
       ->add('hours', 'text'); 

    } 
    public function getDefaultOptions(array $options) 
    { 
     return array('data_class' => 'Parabola\EntityBundle\Entity\TimeSheetDaily'); 
    } 

public function getName() { 
    return 'DailySheet'; 
} 

// - controller--

$repository = $this->getDoctrine() 
       ->getRepository('ParabolaEntityBundle:TimeSheetDaily')->findAll(); 
     $form = $this->createForm(new \Parabola\TimeSheetBundle\Form\TimeSheetType(),$repository); 

我有实体类TimeSheetDaily。在构建TimeSheetType的表单时，我传递TimeSheetDaily类对象的数组以形成类型。并且TimeSheetType具有DailyType的集合。它不是收集字段的设置值，它只是一个TimeSheetDaily实体。

您是否定义了TimeSheetDaily类的__constructor？ 你有这样的事吗？

public function __construct(){ 
//.... 

$this->dailyTimeSheet = new ArrayCollection(); 

//.... 
}; 

，以便正确初始化该集合Symfony能够将数据插入到这一点很重要....
