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
表用户有四列（id、用户名、roleId、描述）表用户角色
有两列（id、名称）
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()
)
);
}
用户类型.php
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('roleId', 'entity', array(
'class' => 'TruckingMainBundle:UsersRole',
'property' => 'name'
))
->...->..
}
我不知道如何在该列表中设置选定的（默认）值，我已经尝试了 5 个小时，但仍然没有结果
我使用了preferred_choices，query_builder -> 我可以通过 critreia 选择的地方（但是我不需要那个）
http://symfony.com/doc/current/reference/forms/types/entity.html
我可以打印我当前的用户 ID -> print_r($user->getRoleId())；
这东西我已经有了。我的“用户”实体与 UserRole 实体
