问题描述
我正在尝试返回一个表单以更新用户实体中的某些属性
I'm trying to return a form to update some attributes in my user entity
我想拥有一个单页应用程序，因此我正在创建表单，尝试在单个控制器中设置其Update函数，并将表单加载到单独的树枝模板中，这些模板都已加载到主个人资料"页面.
I'm tying to have a single page app, so I'm creating forms, trying to setup their Update functions in a single controller, and to load the forms in separate twig templates that are all loaded in the main "profile" page.
我的整个用户控制器:
<?php
namespace App\Controller;
use App\Entity\User;
use App\Form\ModifyUserType;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use App\Repository\UserRepository;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\Security\Core\User\UserInterface;
class UserController extends AbstractController
{
/**
* @Route("/profile", name="profile", methods={"GET"})
*/
public function index(): Response
{
$this->denyAccessUnlessGranted('IS_AUTHENTICATED_FULLY');
return $this->render('profile.html.twig', [
'controller_name' => 'UserController',
]);
}
/**
* @Route("/profile", name="update", methods={"PUT"})
* @param UserInterface $user
* @param Request $request
* @param EntityManagerInterface $em
* @return Response
*/
public function updateUser(UserInterface $user, Request $request, EntityManagerInterface $em) : Response
{
$userId = $this->getUser()->getId();
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository(User::class)->find($userId);
$form = $this->createForm(ModifyUserType::class, $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$user = $form->getData();
$em->persist($user);
$em->flush();
$this->addFlash('success', 'Saved');
return $this->redirectToRoute('profile');
}
return $this->render('modifyUser.html.twig', [
'updateUser' => $form->createView()
]);
}
}
我的表单类型:
<?php
namespace App\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\LanguageType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class ModifyUserType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('description', TextareaType::class)
->add('MotherLanguage', LanguageType::class)
->add('addLanguage', LanguageType::class)
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
// Configure your form options here
]);
}
}
我试图调用表单的模式:
The modal where I'm trying to call the form:
<!-- Modify User Modal -->
<div class="modal fade" role="dialog" id="editUserModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title">Modify profile</h3>
<button class="close" type="button" data-dismiss="modal">×</button>
</div>
{{ form_start(updateUser) }}
<input type="hidden" name="_method" value="PUT">
<div class="modal-body">
<div class="form-group">
<label for="description">Description</label>
{{ form_row(updateUser.description, { 'id': 'description','attr': { 'class' : 'form-control'}}) }}
<label for="addNativeLanguage">Add your native language</label>
{{ form_row(updateUser.MotherLanguage, { 'id': 'addNativeLanguage','attr': { 'class' : 'form-control'}}) }}
</select>
<label for="addLanguage">Add other languages you speak</label>
{{ form_row(updateUser.addLanguage, { 'id': 'addLanguage','attr': { 'class' : 'form-control'}}) }}
</select>
</div>
</div>
<div class="modal-footer">
<button class="btn btn-light">Update</button>
</div>
{{ form_end(updateUser) }}
</div>
</div>
</div>
<!-- /Modify User Modal -->
更新:将控制器修改为以下内容之后:
Update: After Modifying the Controller to the following:
<?php
namespace App\Controller;
use App\Entity\User;
use App\Form\ModifyUserType;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use App\Repository\UserRepository;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\Security\Core\User\UserInterface;
class UserController extends AbstractController
{
/**
* @Route("/profile", name="profile", methods={"GET","PUT"})
*/
public function index(UserInterface $user, Request $request, EntityManagerInterface $em) : Response
{
$this->denyAccessUnlessGranted('IS_AUTHENTICATED_FULLY');
/*return $this->render('profile.html.twig', [
'controller_name' => 'UserController',
]);*/
$userId = $this->getUser()->getId();
$em = $this->getDoctrine()->getManager();
$user = $em->getRepository(User::class)->find($userId);
$form = $this->createForm(ModifyUserType::class, $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$user = $form->getData();
$em->persist($user);
$em->flush();
$this->addFlash('success', 'Article Created! Knowledge is power!');
return $this->redirectToRoute('profile');
}
return $this->render('profile.html.twig', [
'user' => $user,
'updateUser' => $form->createView()
]);
}
}
我遇到了一个新错误:函数App \ Entity \ User :: addLanguage()的参数太少，在第422行的/home/majd/Projects/Symfony/Back/vendor/symfony/property-access/PropertyAccessor.php中传递了0预期.
I'm getting a new error :
Too few arguments to function App\Entity\User::addLanguage(), 0 passed in /home/majd/Projects/Symfony/Back/vendor/symfony/property-access/PropertyAccessor.php on line 422 and exactly 1 expected.
推荐答案
按照@dutycorpse的评论，而不是去寻找该属性，我直接去寻找负责添加语言的函数.
As per @dutycorpse 's comment instead of going for the property, I was going directly for the function responsible for adding languages.
