在我的子类中显示对象时出现问题。创建对象后，它被正确插入到数据库中，但在显示时会导致错误。
以下是继承链接：
- 用户
- 抽象客户端扩展用户
- Mairie 扩展客户
以下是涉及问题的页面代码：
- 用户：
<?php
namespace App\Entity;
use App\Repository\UserRepository;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
/**
* @ORM\Entity(repositoryClass=UserRepository::class)
* @ORM\Table(name="`user`")
*/
class User implements UserInterface
{
/**
* @ORM\Id
* @ORM\GeneratedValue
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=180, unique=true)
*/
private $email;
/**
* @ORM\Column(type="json")
*/
private $roles = [];
/**
* @var string The hashed password
* @ORM\Column(type="string")
*/
private $password;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $firstname;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $lastname;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $Entit;
（加上 getter 和 setter）
- 客户 ：
<?php
namespace App\Entity;
use App\Repository\ClientRepository;
use Doctrine\ORM\Mapping as ORM;
use App\Entity\User;
/**
* @ORM\Entity(repositoryClass=ClientRepository::class)
*/
Abstract class Client extends User
{
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $adresse;
/**
* @ORM\Column(type="integer", nullable=true)
*/
private $cp;
/**
* @ORM\Column(type="string", length=255, nullable=true)
*/
private $ville;
/**
* @ORM\Column(type="string", length=15, nullable=true)
*/
private $telephone;
（加上 getter 和 setter）
- 麦莉：
<?php
namespace App\Entity;
use App\Entity\Client;
use Doctrine\ORM\Mapping as ORM;
use App\Repository\MairieRepository;
/**
* @ORM\Entity(repositoryClass=MairieRepository::class)
*/
class Mairie extends Client
{
}
- 仪表板控制器：
<?php
namespace App\Controller\Admin;
use App\Entity\Elu;
use App\Entity\Client;
use App\Entity\Mairie;
use App\Entity\User;
use App\Entity\CdcColl;
use App\Entity\DashboardKibana;
use App\Repository\UserRepository;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use EasyCorp\Bundle\EasyAdminBundle\Config\MenuItem;
use EasyCorp\Bundle\EasyAdminBundle\Config\Dashboard;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Security;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractDashboardController;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\IsGranted;
class DashboardController extends AbstractDashboardController
{
protected $userRepository;
public function __construct(
UserRepository $userRepository
)
{
$this->userRepository = $userRepository;
}
/**
* @Route("/admin", name="admin")
* @Security("is_granted('ROLE_ADMIN')")
*/
public function index(): Response
{
return $this->render('admin/welcome.html.twig',
[
'countUser' => $this->userRepository->countAllUser()
]
);
}
public function configureDashboard(): Dashboard
{
return Dashboard::new()
->setTitle('SrciToZeendoc');
}
public function configureMenuItems(): iterable
{
yield MenuItem::linktoDashboard('Accueil', 'fa fa-home');
yield MenuItem::linkToCrud('Dashboard', 'fas fa-chart-line', DashboardKibana::class);
yield MenuItem::linkToCrud('Mairie', 'fas fa-landmark', Mairie::class);
yield MenuItem::linkToCrud('Utilisateurs', 'fas fa-users', User::class);
yield MenuItem::linkToCrud('Elu', 'fas fa-user', Elu::class);
yield MenuItem::linkToCrud('Collectivité', 'fas fa-landmark', CdcColl::class);
yield MenuItem::linkToUrl('Retour Site', 'fas fa-undo', '/');
}
}
- MairieCrudController ：
<?php
namespace App\Controller\Admin;
use App\Entity\Mairie;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextField;
use EasyCorp\Bundle\EasyAdminBundle\Field\ChoiceField;
use EasyCorp\Bundle\EasyAdminBundle\Controller\AbstractCrudController;
class MairieCrudController extends AbstractCrudController
{
public static function getEntityFqcn(): string
{
return Mairie::class;
}
public function configureFields(string $pageName): iterable
{
return [
TextField::new('email'),
ChoiceField::new('roles', 'Roles')
->allowMultipleChoices()
->autocomplete()
->setChoices([ 'User' => 'ROLE_USER',
'Mairie' => 'ROLE_MAIRIE',
'Admin' => 'ROLE_ADMIN',
'SuperAdmin' => 'ROLE_SUPER_ADMIN',
'Dashboard' => 'ROLE_DASHBOARD',
'Opendata' => 'ROLE_OPENDATA',
'IOT' => 'ROLE_IOT',
'Coffre Fort' => 'ROLE_COFFRE',
'Certificat SSL' => 'ROLE_SSL',
'GED' => 'ROLE_GED',
'Archivage' => 'ROLE_ARCHIVAGE',
'Statistiques' => 'ROLE_STATISTIQUES',
'Reporting' => 'ROLE_REPORTING',
'Cartographie' => 'ROLE_CARTOGRAPHIE'
]
)
->setPermission("ROLE_SUPER_ADMIN"),
TextField::new('Password')->hideOnIndex(),
TextField::new('Firstname'),
TextField::new('Lastname'),
TextField::new('adresse'),
TextField::new('cp'),
TextField::new('ville'),
TextField::new('telephone')
];
}
}
这是获得的错误：
An exception occurred while executing 'SELECT u0_.id AS id_0, u0_.email AS email_1, u0_.roles AS roles_2, u0_.password AS password_3, u0_.firstname AS firstname_4, u0_.lastname AS lastname_5, u0_.entit AS entit_6, c1_.adresse AS adresse_7, c1_.cp AS cp_8, c1_.ville AS ville_9, c1_.telephone AS telephone_10 FROM mairie m2_ WHERE m2_.id IN (?)' with params [4]:
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'u0_.id' in 'field list'
据我了解，数据库中的插入很好，但是当涉及到显示时，它会在 Mairie 表中查找 id 列（仅存在于 User 类中）。
