Question

我在Symfony（Doctrine）中创建两个表之间的关系时遇到问题。我正在创建地址簿，我有Person Entity，我想要有关系机智地址实体与关系OneToMany（一个人有很多地址）。我跑的时候：

php app/console doctrine:generate:entities AdressBookBundle/Entiti/Address

我收到了错误：

[RuntimeException]                                                                 
  Namespace "AdressBookBundle\Entiti\Address" does not contain any mapped entities.

下面我将代码放在两个实体中：

人：

<?php

namespace AdressBookBundle\Entity;

use AdressBookBundle\Entity\Address;
use Doctrine\ORM\Mapping as ORM;

/**
 * Person
 *
 * @ORM\Table(name="person")
 * @ORM\Entity(repositoryClass="AdressBookBundle\Repository\PersonRepository")
 */
class Person
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="name", type="string", length=255)
     */
    private $name;

    /**
     * @var string
     *
     * @ORM\Column(name="surname", type="string", length=255)
     */
    private $surname;

    /**
     * @var string
     *
     * @ORM\Column(name="description", type="string", length=500)
     */
    private $description;

    /**
     * @ORM\OneToMany(targetEntity="Address", mappedBy="person")
     */
    private $address;


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

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

        return $this;
    }

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

    /**
     * Set surname
     *
     * @param string $surname
     * @return Person
     */
    public function setSurname($surname)
    {
        $this->surname = $surname;

        return $this;
    }

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

    /**
     * Set description
     *
     * @param string $description
     * @return Person
     */
    public function setDescription($description)
    {
        $this->description = $description;

        return $this;
    }

    /**
     * Get description
     *
     * @return string 
     */
    public function getDescription()
    {
        return $this->description;
    }
    /**
     * Constructor
     */
    public function __construct()
    {
        $this->address = new \Doctrine\Common\Collections\ArrayCollection();
    }

    /**
     * Add address
     *
     * @param \AdressBookBundle\Entity\Address $address
     * @return Person
     */
    public function addAddress(\AdressBookBundle\Entity\Address $address)
    {
        $this->address[] = $address;

        return $this;
    }

    /**
     * Remove address
     *
     * @param \AdressBookBundle\Entity\Address $address
     */
    public function removeAddress(\AdressBookBundle\Entity\Address $address)
    {
        $this->address->removeElement($address);
    }

    /**
     * Get address
     *
     * @return \Doctrine\Common\Collections\Collection 
     */
    public function getAddress()
    {
        return $this->address;
    }
}

地址：

<?php

namespace AdressBookBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use AdressBookBundle\Entity\Person;

/**
 * Address
 *
 * @ORM\Table(name="address")
 * @ORM\Entity(repositoryClass="AdressBookBundle\Repository\AddressRepository")
 */
class Address
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

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

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

    /**
     * @var int
     *
     * @ORM\Column(name="house_number", type="integer")
     */
    private $houseNumber;

    /**
     * @var int
     *
     * @ORM\Column(name="house_unit_number", type="integer")
     */
    private $houseUnitNumber;

    /**
     * $@ORM\ManyToOne(targetEntity="Person", inversedBy="address")
     * @ORM\JoinColumn(name="person_id", referencedColumnName="id")
     */
    private $person;

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

    /**
     * Set city
     *
     * @param string $city
     * @return Address
     */
    public function setCity($city)
    {
        $this->city = $city;

        return $this;
    }

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

    /**
     * Set street
     *
     * @param string $street
     * @return Address
     */
    public function setStreet($street)
    {
        $this->street = $street;

        return $this;
    }

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

    /**
     * Set houseNumber
     *
     * @param integer $houseNumber
     * @return Address
     */
    public function setHouseNumber($houseNumber)
    {
        $this->houseNumber = $houseNumber;

        return $this;
    }

    /**
     * Get houseNumber
     *
     * @return integer 
     */
    public function getHouseNumber()
    {
        return $this->houseNumber;
    }

    /**
     * Set houseUnitNumber
     *
     * @param integer $houseUnitNumber
     * @return Address
     */
    public function setHouseUnitNumber($houseUnitNumber)
    {
        $this->houseUnitNumber = $houseUnitNumber;

        return $this;
    }

    /**
     * Get houseUnitNumber
     *
     * @return integer 
     */
    public function getHouseUnitNumber()
    {
        return $this->houseUnitNumber;
    }
}

你能解释一下它是如何起作用的吗？据我所知，我通过以下方式建立关系：

/**
     * $@ORM\ManyToOne(targetEntity="Person", inversedBy="address")
     * @ORM\JoinColumn(name="person_id", referencedColumnName="id")
*/

并且neew列person_id正在地址表中创建。我是对的吗？

Answer 1

注释中有错误：

$@ORM\ManyToOne(targetEntity="Person", inversedBy="address")

应该是

@ORM\ManyToOne(targetEntity="Person", inversedBy="address")

删除 $ 以使其正常工作。

Answer 2

从@ORM \ ManyToOne（targetEntity =“Client”）中删除“$”。

@ORM \多对一（targetEntity = “客户”）。删除“$”

Symfony 2.8无法在两个表之间创建关系
