Question

当客户可以执行诸如查看地址列表以及添加/更新/删除地址之类的操作时，请尝试添加客户部分。一个

因此，我正在努力迈出第一步，使客户实体像这样

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Customer
 *
 * @ORM\Table(name="customer")
 * @ORM\Entity(repositoryClass="AppBundle\Repository\CustomerRepository")
 */
class Customer 
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="text")
     */
    private $name;

    /**
     * @var string
     *
     * @ORM\Column(name="address", type="text")
     */
    private $address;

    /**
     * @ORM\OneToOne(targetEntity="User", inversedBy="customer")
     */
    private $user;

    /**
    * @ORM\OneToOne(targetEntity="Cart", mappedBy="user", cascade={"persist"})
    */
    protected $cart;

    // public function __construct()
    // {
    //     parent::__construct();
    //     // your own logic
    // }

    // other properties and methods


    /**
     * Get id
     *
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set name
     *
     * @param string $name
     *
     * @return Customer
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Set address
     *
     * @param string $address
     *
     * @return Customer
     */
    public function setAddress($address)
    {
        $this->address = $address;

        return $this;
    }

    /**
     * Get address
     *
     * @return string
     */
    public function getAddress()
    {
        return $this->address;
    }

    /**
     * Set cart
     *
     * @param \AppBundle\Entity\Cart $cart
     * @return User
     */
    public function setCart(\AppBundle\Entity\Cart $cart = null)
    {
        $this->cart = $cart;
        return $this;
    }
    /**
     * Get cart
     *
     * @return \AppBundle\Entity\Cart 
     */
    public function getCart()
    {
        return $this->cart;
    }

    // public function __construct()
    // {
    //     parent::__construct();

    //     $this->addRole("ROLE_CUSTOMER");
    // }
}

当我访问本地主机/客户时，我收到了这样的错误消息

执行'SELECT t0.id AS id_1，t0.name时发生异常   AS名称_2，t0.address AS地址_3，t0.user_id AS user_id_4，t5.id AS   id_6，t5.total_price AS total_price_7，t5.quantity AS数量_8，   t5.user_id AS user_id_9来自客户t0左加入购物车t5开   t5.user_id = t10.id'：

我确实在stackoverflow中打开了一些线程，但是其中许多仍然使我困惑，无法找到解决此问题的明确答案，该主题主要讨论的是postgres而不是实体。

这是我的客户经理

        } else {
            return $this->render('customer/new.html.twig', array(
                'form' => $form->createView(),

    public function deleteAction($id) {
        $doct = $this->getDoctrine()->getManager();
        $user = $doct->getRepository('AppBundle:Customer')->find($id);

        if (!$user) {
            throw $this->createNotfoundException('No customer found for id ',$id);

        $doct->remove($user);
        $doct->flush();
        return $this->redirectToRoute('address_display');
    }
}

我希望输出结果可以再次访问客户显示操作路由器，并显示来自客户控制器的所有数据。

我不知道为什么这可以解决此问题，所以我尝试取消注释此行

public function __construct()
    {
        parent::__construct();

        $this->addRole("ROLE_CUSTOMER");
    }

它解决了我可以打开并访问localhost / customer的问题
