Symfony 4 - FOSUserBundle - 在自定义路由上呈现用户信息

Question

我的自定义 ProfileController 中有一个构造函数和路由

private $userManager;

public function __construct(UserManagerInterface $userManager)
{
    $this->userManager = $userManager;
}

/**
 * @Route("/profile/bookings", name="profile_bookings")
 */
public function bookings()
{

    $user = $this->getUser();

    return $this->render('profile/bookings/bookings.html.twig', array('user'=>$user));
}

在我的模板中我引用了

{{ user.first_name }}

但我得到了错误：

HTTP 500 内部服务器错误 属性“first_name”和方法“first_name()”、“getfirst_name()”/“isfirst_name()”/“hasfirst_name()”或“__call()”都不存在，并且在类“App\”中具有公共访问权限实体\用户”。

我如何从数据库中获取用户信息并显示在个人资料的子页面中？

编辑：用户实体 ...

<?php

Answer 1

@Franck Gamess 是对的，但您也可以摆脱 get。 如果你写{{ user.firstName }}，twig 会自动将它关联到你的方法getFirstName()。

我不知道你为什么用snake_case 编写你的属性，但你可以将它更改为camelCase 并通过它们的“真实”名称访问你的属性。

Answer 2

只需在你的树枝模板中使用：

{{ user.getFirstName }}

它工作正常。通常 Twig 在 PHP 层所做的事情非常简单：

check if user is an array and first_name a valid element;
if not, and if user is an object, check that first_name is a valid property;
if not, and if user is an object, check that first_name is a valid method (even if first_name is the constructor - use __construct() instead);
if not, and if user is an object, check that getfirst_name is a valid method;
if not, and if user is an object, check that isfirst_name is a valid method;
if not, and if user is an object, check that hasfirst_name is a valid method;
if not, return a null value.

见Twig variables。

顺便说一句，您应该遵循Symfony Coding Standard 作为变量，因为twig 很难找到用snake_case 编写的属性的值。

Answer 3

我认为您不应该在控制器中构造UserManagerInterface。另外，就像 Franck 所说，如果可以，请使用编码标准，这将在未来节省大量时间和挫败感！

这是我在 Symfony 4 项目中使用的控制器：

namespace App\Controller;

use FOS\UserBundle\Model\UserInterface;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\Exception\AccessDeniedException;

/**
 * @Route("/profile/bookings", name="profile_bookings")
 */
public function bookings()
{
    $user = $this->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    return $this->render('profile/bookings/bookings.html.twig', array(
        'user' => $user,
    ));
    }
}
