我使用Symfony 2从数据库中获取所有用户时出现此错误:
Variable "name" does not exist in UsersListBundle:Default:index.html.twig at line 1
500 Internal Server Error - Twig_Error_Runtime
我的代码:index.html.twig

<p>All users in the users table using: <br />

{% else %}

<p>Get ID 1 in the example table using: <br />
<strong>$user = $this->getDoctrine()->getRepository('UsersListBundle:Users')->find(1);</strong></p>

</div>

这是我的控制器代码:
/**
* @Route("/users")
* @Template()
*/
public function indexAction()
{
$repository = $this->getDoctrine()
->getRepository('UsersListBundle:Users');
$users = $repository->findAll();
return array('users' => $users);
}
我读过一些关于这个错误的文章。他们说有个隐藏的角色。当你按下Alt + Gr + Space时，这个字符会出现。现在我不知道如何去掉那个字符。我试着重新输入相同的代码，但没有运气。
这是我的用户实体:
<?php
// src/Users/Bundle/ListBundle/Entity/Users.php
namespace Users'Bundle'ListBundle'Entity;
use Doctrine'ORM'Mapping as ORM;
/**
* @ORM'Entity
* @ORM'Table(name="users")
*/
class Users
{
/**
* @ORM'Column(type="integer")
* @ORM'Id
* @ORM'GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @ORM'Column(type="string", length=255)
*/
protected $name;
/**
* @ORM'Column(type="string", length=200)
*/
protected $email;
/**
* @ORM'Column(type="string", length=60)
*/
protected $phone;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* @param string $name
* @return Users
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* @return string
*/
public function getName()
{
return $this->name;
}
/**
* Set email
*
* @param string $email
* @return Users
*/
public function setEmail($email)
{
$this->email = $email;
return $this;
}
/**
* Get email
*
* @return string
*/
public function getEmail()
{
return $this->email;
}
/**
* Set phone
*
* @param string $phone
* @return Users
*/
public function setPhone($phone)
{
$this->phone = $phone;
return $this;
}
/**
* Get phone
*
* @return string
*/
public function getPhone()
{
return $this->phone;
}
}
这是我的UserController:
<?php
namespace Users'Bundle'ListBundle'Controller;
use Symfony'Bundle'FrameworkBundle'Controller'Controller;
use Sensio'Bundle'FrameworkExtraBundle'Configuration'Route;
use Sensio'Bundle'FrameworkExtraBundle'Configuration'Template;

use Symfony'Component'HttpFoundation'Request;
class UsersController extends Controller
{
/**
* @Route("/users")
* @Template()
*/
public function indexAction()
{
$repository = $this->getDoctrine()
->getRepository('UsersListBundle:Users');
$users = $repository->findAll();
return array('users' => $users);
}
/**
* @Route("/users/add")
* @Template()
*/
public function addAction(Request $request)
{
$user= new Users();
$user->setName('Name');
$user->setEmail('Email');
$user->setPhone('Phone');
$form=$this->createFormBuilder($user)
->add('name')
->add('email')
->add('phone')
->getForm();
if ($request->getMethod()=='POST'){
$form->bind($request);
if ($form->isValid()){
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
return $this->redirect($this->generateUrl('users_list_users_index'), 301);
}
} else {
return $this->render('UsersListBundle:Users:add.html.twig',array(
'form'=>$form->createView(),
));
}
}
/**
* @Route("/users/edit/{id}", requirements={"id" = "'d+"}, defaults={"id" = 0})
* @Template()
*/
public function editAction($id, Request $request)
{
if ($id == 0){ // no user id entered
return $this->redirect($this->generateUrl('users_list_users_index'), 301);
}
$user = $this->getDoctrine()
->getRepository('UsersListBundle:Users')
->find($id);
if (!$user) {// no user in the system
throw $this->createNotFoundException(
'No user found for id '.$id
);
}
$form=$this->createFormBuilder($user)
->add('name')
->add('email')
->add('phone')
->getForm();
if ($request->getMethod()=='POST'){
$form->bind($request);
if ($form->isValid()){
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush();
return $this->redirect($this->generateUrl('users_list_users_index'), 301);
}
} else {
return $this->render('UsersListBundle:Users:edit.html.twig',array(
'form'=>$form->createView(),
));
}
return array('name' => $id);
}
/**
* @Route("/users/delete/{id}", requirements={"id" = "'d+"}, defaults={"id" = 0})
* @Template()
*/
public function deleteAction($id)
{
if ($id == 0){ // no user id entered
return $this->redirect($this->generateUrl('users_list_users_index'), 301);
}
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository('UsersListBundle:Users')->find($id);
if (!$user) { // no user in the system
throw $this->createNotFoundException(
'No user found for id '.$id
);
} else {
$em->remove($user);
$em->flush();
return $this->redirect($this->generateUrl('users_list_users_index'), 301);
}
}
}
这一行有语法问题:
{% if users is not empty %)
替换 %) , %}
可能没有这样的字段名。这个错误是否出现在第1行:
<!DOCTYPE html>
或
<td>{{ user.name }}</td>
尝试删除第二个，并检查是否仍然有错误。
你能给我看一下用户或UsersListBundle的twig dump: users实体吗
.....
{% if users is not empty %)
{% dump(users) %}
.....
如果在数据库中添加或重命名'name'字段，则必须重新生成实体。将Users实体添加到问题中可以帮助您获得更快的响应。
