【问题描述】：

我正在让用户编辑。 我想通过 Users.role_id = UsersRole.id 查看当前用户的选定角色 Users 表有四列（id、username、roleId、descriptions）UsersRole 表有两列 (id,name)

控制器：

public function editAction($id) 
    $user = $this->getDoctrine()
            ->getEntityManager()
            ->getRepository('TruckingMainBundle:Users')
            ->find($id);

    if (!$user) 
        throw $this->createNotFoundException('Unable to find user id.');
    
    $form = $this->createForm(new \Trucking\AdminBundle\Form\UserType(), $user);
    $request = $this->getRequest();

    //save data
    if ($request->getMethod() == 'POST') 
        $form->bindRequest($request);
        if ($form->isValid()) 
            $em = $this->getDoctrine()->getEntityManager();
            $em->persist($user);
            $em->flush();
            return $this->redirect($this->generateUrl('tracking_admin_users'));
        
    
    return $this->render('TruckingAdminBundle:user:edit.html.twig', array(
                'id' => $id,
                'form' => $form->createView()
                    )
    );

UserType.php

    public function buildForm(FormBuilderInterface  $builder, array $options) 

     $builder
        ->add('roleId', 'entity', array(
                'class' => 'TruckingMainBundle:UsersRole',
                'property' => 'name'
        ))
        ->...->..
    

我不知道如何在该列表中设置选定（默认）值，我已经尝试了 5 个小时，但仍然没有结果我使用过 preferred_choices , query_builder -> 我可以通过 critreia 选择（但我不需要）http://symfony.com/doc/current/reference/forms/types/entity.html

我可以打印我当前的用户 ID -> print_r($user->getRoleId()); 我已经有了。 我的“用户”实体与 UserRole 实体有关联用户实体

用户类型（用于表单）

<?php

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Validator\Constraints;

class UserType extends AbstractType 

    public function buildForm(FormBuilderInterface  $builder, array $options) 

     $builder
        ->add("username","text",array(
                   "label" => "Name",
                       'attr'   =>  array(
                           'class'   => 'input-xlarge',
                       ),
                    'constraints' => new Constraints\Length(array('min' => 3))
                   ))
        ->add('roleId', 'entity', array(
                'class' => 'TruckingMainBundle:UsersRole',
                "label" => "Roles",
                'property' => 'name'
        ))
        ->add("description","text",array(
           "label" => "Description",
               'attr'   =>  array(
                   'class'   => 'input-xlarge'
               ),
                'constraints' => new Constraints\NotBlank()
           ));
    

    public function getName()
    
        return 'trucing_adminbundle_usertype';
    

【问题讨论】：

我不完全确定也懒得去检查，但$builder->add('roleId', 'entity', array('data' => 'ROLE_ADMIN')) 应该可以。至少这是您在country 和choice 字段中设置默认值的方式？

***.com/questions/7913086/…

'data' => 'ROLE_USER' 不起作用，我尝试使用 'preferred_choices' => array('ROLE_USER') 并且出现错误：警告：spl_object_hash() 预期参数1为对象，给定字符串

是不是你必须指定 id 而不是 ROLE_USER，例如1？否则，您可以以某种方式操作查询，以便所需的默认值将成为结果集中的第一个条目。可能不是最好的解决方案，但应该可以...

【参考方案1】：

在呈现表单之前设置实体的属性：

if (!$user) 
    throw $this->createNotFoundException('Unable to find user id.');


//THIS IS NEW
$theRole = getRoleEntityFromSomewhereItMakesSense();
$user->setRole($theRole); //Pass the role object, not the role's ID

$form = $this->createForm(new \Trucking\AdminBundle\Form\UserType(), $user);
$request = $this->getRequest();

当您生成表单时，它会自动填充您正在使用的实体的属性。

编辑 改变

->add('roleId', 'entity', array(

到

->add('roles', 'entity', array(

我不明白你为什么同时拥有 roleId 和 roles。

还要更改以下内容，因为 roles 是单个元素，而不是数组（您有一个一对一的关系，并且应该是一对多的并且尽可能多地反转一对一，但我想它也会起作用）

public function getRoles() 
    return $this->roles;


public function setRoles($role) 
    $this->roles = $role;

【讨论】：

我没听懂，但是你应该把洞实体传递给$user->setRole($theRole);，我会编辑我的答案

只需将其添加到您的实体中，例如 setRole($r)$this->roles = array($r);，实际实现取决于您的要求，但不应该很复杂。

我创建了 $user->setRoles(new \Trucking\MainBundle\Entity\UsersRole()); + I public function setRoles($role) $this->roles = array($role); ，但仍然没有..我正在考虑依赖..

在创建此主题之前，我已经阅读了您的想法，但我不明白，我需要实现什么才能使这个简单的事情发生

您的实体应该包含一组属性以及 getter 和 setter。这就是信息被持久化并通过应用程序传递的方式。表单只是让用户在您的实体上设置值的一种简单方式，因此它们都是连接的。当您呈现表单时，它只会显示实体包含的数据，仅此而已。为什么不发布实体的完整代码？

【参考方案2】：

ORM JOINS 出现问题。 id 到 role_id 我已将映射从一对一 双向 到一对一，单向与连接表。
