原则2：ORM，刷新后零外键

问题描述

| 我正在使用Doctrine 2 ORM，但我遇到了这个问题。我有三个实体，地址，位置和OrganizationalUnit。它们之间的关系是：地址（OneToOne）位置， OrganizationalUnit（ManyToOne）地址。问题：当我尝试保留所有对象（下面的代码）时，它将OrganizationalUnit（FK：Address）设置为零，而不是Address（ID）。当我选择（查找）或更新某些东西时，一切正常。码：这是使持久化的代码。

//Entity manager
$em = Zend_Registry::get(\'em\');

$location = new Application_Model_Location();
$location->setLatitude(0);
$location->setLongitude(0);

$address = new Application_Model_Address();
$address->setCity(\'test\');
$address->setCountry(\'cz\');
$address->setNumber(123456);
$address->setPostalCode(123456);
$address->setStreet(\'street\');

$address->setLocation($location);
$location->setAddress($address);

$organization = new Application_Model_Organizationalunit();
$organization->setName(\'novytest\');
$organization->setType($organizationType[0]);

$address->addOrganization($organization);
$organization->setAddress($address);

$em->persist($location);
$em->persist($address);
$em->persist($organization);

$em->flush();

这段代码生成这样的SQL（我从MySQL Server Log获得它）

START TRANSACTION
INSERT INTO Location (longitude,latitude,cartographicSquare,id) VALUES (\'0\',\'0\',NULL,NULL)
INSERT INTO Address (street,number,city,postalCode,country,id) VALUES (\'ulice\',\'123456\',\'test\',\'cz\',11)
INSERT INTO OrganizationalUnit (name,type,address,parentId) VALUES (\'novytest\',7,NULL)
ROLLBACK

Wich错误的\'（\'（\'novytest \'，7，0，NULL）\'这个零的原因（下面的数据模型）数据看起来像这样：

CREATE TABLE  `rotifera`.`location` (
  `id` int(11) NOT NULL AUTO_INCREMENT,`longitude` double NOT NULL,`latitude` double NOT NULL,`cartographicSquare` int(11) DEFAULT NULL,PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE  `rotifera`.`address` (
  `id` int(11) NOT NULL DEFAULT \'0\',`street` varchar(100) NOT NULL,`number` varchar(20) NOT NULL,`city` varchar(100) NOT NULL,`postalCode` varchar(10) NOT NULL,`country` varchar(100) NOT NULL,PRIMARY KEY (`id`),KEY `fk_Address_Location` (`id`),CONSTRAINT `fk_Address_Location` FOREIGN KEY (`id`) REFERENCES `location` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE  `rotifera`.`organizationalunit` (

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

我的ORM模型如下所示对于位置：

/**
 * @Entity
 * @table(name=\"Location\")
 */
class Application_Model_Location {

    /**
     * @id @column(type=\"integer\")
     * @generatedValue
     */
    private $id;
    /** @column(type=\"float\") */
    private $longitude;
    /** @column(type=\"float\") */
    private $latitude;
    /** @column(type=\"integer\",nullable=true) */
    private $cartographicSquare;
    /**
    * @OneToOne(targetEntity=\"Application_Model_Address\",mappedBy=\"location\")
    */
    private $address;

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

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

public function getLongitude() {
    return $this->longitude;
}

public function setLongitude($longitude) {
    $this->longitude = $longitude;
}

public function getLatitude() {
    return $this->latitude;
}

public function setLatitude($latitude) {
    $this->latitude = $latitude;
}

public function getCartographicSquare() {
    return $this->cartographicSquare;
}

public function setCartographicSquare($cartographicSquare) {
    $this->cartographicSquare = $cartographicSquare;
}

public function getAddress() {
    return $this->address;
}

public function setAddress($address) {
    $this->address = $address;
}

地址：

/**
 * @Entity
 * @table(name=\"Address\")
 */
class Application_Model_Address {

    /**
     * @id 
     * @column(type=\"integer\")
     * @generatedValue
     */
    private $id;
    /** @column(length=100) */
    private $street;
    /** @column(length=100) */
    private $number;
    /** @column(length=100) */
    private $city;
    /** @column(length=100) */
    private $postalCode;
    /** @column(length=100) */
    private $country;
    /**
    * @OneToOne(targetEntity=\"Application_Model_Location\",inversedBy=\"address\")
    * @JoinColumn(name=\"id\",referencedColumnName=\"id\")
    */
    private $location;
    /**
    * @OneToMany(targetEntity=\"Application_Model_Organizationalunit\",mappedBy=\"address\")
    */
    private $organization;

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

public function getId() {
    return ($this->id > 0) ? $this->id : $this->location->getId();
}

public function getStreet() {
    return $this->street;
}

public function setStreet($street) {
    $this->street = $street;
}

public function getNumber() {
    return $this->number;
}

public function setNumber($number) {
    $this->number = $number;
}

public function getCity() {
    return $this->city;
}

public function setCity($city) {
    $this->city = $city;
}

public function getPostalCode() {
    return $this->postalCode;
}

public function setPostalCode($postalCode) {
    $this->postalCode = $postalCode;
}

public function getCountry() {
    return $this->country;
}

public function setCountry($country) {
    $this->country = $country;
}

public function getLocation() {
    return $this->location;
}

public function setLocation($location) {
    $this->location = $location;
}

public function getOrganization() {
    return $this->organization;
}

public function addOrganization($organization) {
    $this->organization->add($organization);
}

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

对于OrganizationalUnit

/**
 * @Entity
 * @table(name=\"OrganizationalUnit\")
 */
class Application_Model_Organizationalunit {

    /**
     * @id 
     * @column(type=\"integer\")
     * @generatedValue
     */
    private $id;
    /** @column(length=100) */
    private $name;
    /**
     * @ManyToOne(targetEntity=\"Application_Model_Organizationalunittype\",*   inversedBy=\"id\")
     * @JoinColumn(name=\"type\",*   referencedColumnName=\"id\")
     */
     private $type;
     /**
      * @ManyToOne(targetEntity=\"Application_Model_Address\",inversedBy=\"organization\")
      * @JoinColumn(name=\"address\",referencedColumnName=\"id\")
      */
    private $address;
    /**
     * @OneToOne(targetEntity=\"Application_Model_Organizationalunit\")
     * @JoinColumn(name=\"parentId\",*  referencedColumnName=\"id\")
     */
    private $parentId;

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

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

public function getName() {
    return $this->name;
}

public function setName($name) {
    $this->name = $name;
}

public function getType() {
    return $this->type;
}

public function setType($type) {
    $this->type = $type;
}

public function getAddress() {
    return $this->address;
}

public function setAddress($address) {
    $this->address = $address;
}

public function getParentId() {
    return $this->parentId;
}

public function setParentId($parentId) {
    $this->parentId = $parentId;
}

我真的不知道这是怎么回事，这个问题不仅发生在这里，而且当我有ManyToMany关系并且即时将双方插入同花顺时。编辑：而且我还注意到，当我坚持并仅刷新地址和位置时，并且在刷新后对其进行存储时，只有位置的ID和地址为零（在刷新之前为NULL）。感谢您的时间。

解决方法

这是行不通的，因为您两次声明了地址和组织之间的关系。将组织更改为：

/**
 * @Entity
 * @table(name=\"OrganizationalUnit\")
 */
class Application_Model_Organizationalunit {

    ...

    /**
     * @ManyToOne(targetEntity=\"Application_Model_Address\",inversedBy=\"organisation\")
     * @JoinColumn(name=\"address\",referencedColumnName=\"id\")
     */
    private $address;

    ...
}

/**
 * @Entity
 * @table(name=\"Address\")
 */
class Application_Model_Address {

    ...

    /**
     * @OneToMany(targetEntity=\"Application_Model_Organizationalunit\",mappedBy=\"address\")
     */
    private $organization;
}

编辑查看您的位置模型，发现以下行：

/**
 * @OneToOne(targetEntity=\"Application_Model_Location\",inversedBy=\"address\")
 * @JoinColumn(name=\"id\",referencedColumnName=\"id\")
 */
private $location;

您将位置参考自动递增的主键。它可以与此有关吗？您可能需要在地址表中添加location_id列。现在，您为ID列分配了两次值。附言看来还有更多的事情无法正常工作，因此必须一次解决一个问题。
