Symfony2.7在樹枝中顯示combox項目

Question

我有一個名爲公司和部門的表。公司與部門有一對多的關係。我創建了兩個實體並在兩者中指定了關係。請在兩個實體

看看Department.php

<?php 

namespace Benerite\CompanyBundle\Entity; 

use Doctrine\ORM\Mapping as ORM; 
use Doctrine\Common\Collections\ArrayCollection;

    public function __toString() 
    { 
     return (string)$this->getId(); 
    } 
} 

我一直在使用這兩者和其正確的創建模式。我已經爲兩個實體生成了crud表單，並且也給了我正確的表單。問題是，在我的部門創建和編輯頁面，它給了我這樣一個組合框渲染

<select id="benerite_companybundle_department_company" name="benerite_companybundle_department[company]"> 
    <option value=""></option>    
    <option value="1">1</option>    
    <option value="2">2</option> 
</select> 

時，這是不是真的，我希望它應該MBE像

<select id="benerite_companybundle_department_company" name="benerite_companybundle_department[company]"> 
     <option value="">please select</option>    
     <option value="1">comapny 1</option>    
     <option value="2">comapny 2</option> 
    </select> 

這裏是我的new.twig.html文件

{% extends '::base.html.twig' %} 

{% block body -%} 
    <h1>Department creation</h1> 
    {{ form_start(form) }} 

     <div> 
      {{ form_label(form.company) }} 
      {{ form_widget(form.company) }} 

     </div> 
     <div> 
      {{ form_label(form.departmentStatus) }} 
      {{ form_widget(form.departmentStatus) }} 
     </div> 

     <div> 
      {{ form_label(form.departmentName) }} 
      {{ form_widget(form.departmentName) }} 

     </div> 

    {{ form_end(form) }} 

    <ul class="record_actions"> 
     <li> 
      <a href="{{ path('department') }}"> 
       Back to the list 
      </a> 
     </li> 
    </ul> 
{% endblock %} 

我使用symfony2.7和mysql作爲數據庫。

Answer 1

你可以象下面這樣：

public function buildForm(FormBuilderInterface $builder, array $options) 
{ 
     $builder 
      ->add('company', 'entity', array(
       'class' => 'BeneriteCompanyBundle:Company', 
       'choice_label' => 'companyName' 
     ) 
      ->add('departmentName') 
      ->add('departmentStatus') 
     ; 
} 

我希望這將工作，只要你想。

或者，如果你要編寫自定義查詢經過下面的網址： http://symfony.com/doc/current/reference/forms/types/entity.html#using-a-custom-query-for-the-entities
