【中文标题】“关联是指反边场”&“映射相互不一致”

【英文标题】："association refers to the inverse side field" & "mappings are inconsistent with each other"

【问题描述】：

我有两个实体，一个用于预订，一个用于可以进行预订的桌子。 该实体具有多对多关系。当我尝试验证此架构时，我收到以下错误：

映射 Test\TestBundle\Entity\Table#reservations 和 Test\TestBundle\Entity\Reservation#tables 与每个不一致 其他。 关联 Test\TestBundle\Entity\Reservation#tables 指反边字段 Test\TestBundle\Entity\Table#tables 不存在。

我能得到一些帮助吗？我不知道我做错了什么。

表实体：

/**
*
* @ORM\Entity
* @ORM\Table(name="tables")
* @ORM\Entity(repositoryClass="Test\TestBundle\Repository\TableRepository")
*/
class Table     
 /**
 * @var integer $id
 * @ORM\ID
 * @ORM\Column(name="id", type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @ORM\Column(type="integer", length=3)
 */
protected $nmbr;

/**
 * @ORM\ManyToMany(targetEntity="Reservation", mappedBy="tables", cascade="persist")
 */
private $reservations;


public function addReservation($reservation) 
    $reservation->addTable($this);
    $this->reservations[] = $reservation;




public function getId() 
    return $this->id;


public function getNmbr() 
    return $this->nmbr;


public function getReservations() 
    return $this->reservations;


public function setId($id) 
    $this->id = $id;


public function setNmbr($nmbr) 
    $this->nmbr = $nmbr;


/**
 * overrides the array of reservations belonging to this tabke in $reservations
 * with the given array of reservations.
 * Also adds this table to every reservations in the array.
 *
 */
public function setReservations($reservations) 
    foreach ($reservations as $reservation) 
        $reservation->addTable($this);
    
    $this->reservations = $reservation;


public function __toString() 
    return (string)$this->getNmbr();


public function __construct() 
    parent::__construct();
    $this->reservations = new ArrayCollection();

预订实体：

/**
 * @ORM\Entity(repositoryClass="Test\TestBundle\Repository\ReservationRepository")
 * @ORM\Table(name="reservations")
 * @ORM\HasLifecycleCallbacks()
 */
class Reservation 

/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;    

 /**
 * @ORM\ManyToMany(targetEntity="Table", inversedBy="tables")
 * @ORM\JoinTable(name="reservation_table")
 **/
protected $tables;    

/**
 * @ORM\Column(type="string", length=32)
 */
protected $firstname;

/**
 * @ORM\Column(type="string", length=32)
 */
protected $lastname;

/**
 * @ORM\Column(type="string", length=32)
 */
protected $phone;

/**
 * @ORM\Column(type="string", length=32)
 */
protected $email;

/**
 * @ORM\Column(type="text",  nullable=true)
 */
protected $message;

/**
 * @ORM\Column(type="date")
 */
protected $date;

 /**
 * @ORM\Column(type="string", length=32)
 */
protected $timeFrom;

 /**
 * @ORM\Column(type="string", length=32)
 */
protected $timeTo;

public function addTable($table) 
    $this->tables[] = $table;

public function getTables() 
    return $this->tables;


public function getId() 
    return $this->id;



public function getFirstname() 
    return $this->firstname;


public function getLastname() 
    return $this->lastname;


public function getPhone() 
    return $this->phone;


public function getEmail() 
    return $this->email;


public function getMessage() 
    return $this->message;


public function getDate() 
    return $this->date;


public function getTimeFrom() 
    return $this->timeFrom;


public function getTimeTo() 
    return $this->timeTo;


public function setId($id) 
    $this->id = $id;


public function setTables($tables) 
    $this->tables = $tables;


public function setFirstname($firstname) 
    $this->firstname = $firstname;


public function setLastname($lastname) 
    $this->lastname = $lastname;


public function setPhone($phone) 
    $this->phone = $phone;


public function setEmail($email) 
    $this->email = $email;


public function setMessage($message) 
    $this->message = $message;


public function setDate($date) 
    $this->date = $date;


public function setTimeFrom($timeFrom) 
    $this->timeFrom = $timeFrom;


public function setTimeTo($timeTo) 
    $this->timeTo = $timeTo;



public function __construct() 
    $this->tables = new \Doctrine\Common\Collections\ArrayCollection();

【参考方案1】：

在Reservation实体inversedBy属性中，你应该指向相应的字段，所以resevations，而不是tables：

/**
 * @ORM\ManyToMany(targetEntity="Table", inversedBy="reservations")
 * @ORM\JoinTable(name="reservation_table")
 **/
protected $tables;
