Question

我正在进行用户编辑。
我想通过Users.role_id = UsersRole.id查看当前用户的所选角色

表用户有四列（id，username，roleId，description）
表 UsersRole 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'
        ))
        ->...->..
    }

我不知道如何设置该列表中的选定（默认）值，我一直试图做5个小时，但仍然没有结果

我用过 preferred_choices ， query_builder - ＆gt;我可以通过critreia选择（但我不需要） http://symfony.com/doc/current/reference/forms/types/entity.html enter image description here

我可以打印我当前的用户ID - ＆gt; print_r（$ user-＆gt; getRoleId（））;我已经拥有它了。我的“用户”实体与UserRole实体有连接

Answer 1

在呈现表单之前在实体上设置属性：

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();

生成表单时，会自动填充您正在使用的实体的属性。

修改改变

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

到

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

我不明白为什么你同时拥有 roleId 和角色。

同样更改以下内容，因为角色是一个单独的元素，而不是一个数组（你有一对一的关系，并且应该是一对多并且反转尽可能多到一个，但我想它也会起作用）

public function getRoles() { return $this->roles; } public function setRoles($role) { $this->roles = $role; }

Answer 2

ORM JOINS存在问题。 id to role_id

我已经从一对一双向更改了映射使用连接表进行一对一，单向。
