Symfony2的：收集驗證導致實體領域的錯誤

Question

與集合場，其中收集包含實體領域（會員類型EID）形式，將收集的確認將導致實體領域引發以下錯誤：

An exception has been thrown during the rendering of a template ("Notice: Object of class Mana\ClientBundle\Entity\Ethnicity could not be converted to int

未驗證，實體字段處理正確。並且將實體字段添加到驗證器不起作用。

收集：

->add('members', 'collection', array(
    'type' => new MemberType(), 
    'allow_add' => true, 
    'allow_delete' => true, 
    'by_reference' => false, 
    'prototype' => true, 
))   

會員類型：

->add('include', 'choice', array(
    'choices' => array('Yes' => 'Yes', 'No' => 'No'), 
    'empty_value' => false, 
    'required' => false)) 
->add('fname', null, array('required' => false)) 
->add('sname', null, array('required' => false)) 
->add('dob', 'dob_age') 
->add('gender', 'choice', array(
    'choices' => array('Male' => 'Male', 'Female' => 'Female'), 
    'empty_value' => false, 
    'required' => false)) 
->add('eid', 'entity', array(
    'property' => 'abbr', 
    'label' => '', 
    'class' => 'ManaClientBundle:Ethnicity', 
    'query_builder' => function(EntityRepository $er) { 
     return $er->createQueryBuilder('e') 
       ->orderBy('e.abbr', 'ASC'); 
    } 
)); 

驗證：

/** 
* @Assert\Collection(
* fields = { 
*  "fname" = @Assert\NotBlank(message = "Member first name may not be blank"), 
*  "dob" = @Assert\NotBlank(message = "Member DOB may not be blank"),

Answer 1

原來我的錯誤是假設收集字段需要收集驗證器。相反，驗證者只需要在包含該集合的實體上。在這種情況下，我真正需要做的是在成員實體中指定驗證（並刪除客戶端實體中的註釋斷言。）當我簡化種族實體時，字段被正確處理。所以我的錯誤還包括了Symfony更復雜的概念 - 並非總是如此，有時只是真的！

Answer 2

請問您的會員單位有你的種族實體的關係？從「eid」這個名字來看，它看起來像是在試圖將一個種族類強制爲一個整數字段（「eid」）。

如果沒有看到兩個實體都很難找到任何東西。
