问题描述
我尝试在 Doctrine 2.0 中设置一对多/多对一实体关联.因为我需要关联表 user_message 中的读取"字段，所以我有 3 个实体.
I try to setup an one-to-many / many-to-one entity association in Doctrine 2.0. Because i need a field "read" in the association-table user_message i've got 3 entities.
用户.php
namespace Console\Entity;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @Entity(repositoryClass="Console\Repository\User")
* @Table(name="user")
*/
class User {
/**
* @Id
* @GeneratedValue
* @Column(type="integer")
*/
protected $id;
/**
* @OneToMany(targetEntity="Message", mappedBy="users", cascade={"all"}, orphanRemoval=true)
* @JoinTable(name="user_message",
* joinColumns={@JoinColumn(name="user_id", referencedColumnName="id")},
* inverseJoinColumns={@JoinColumn(name="message_id", referencedColumnName="id", unique=true)}
* )
*/
protected $messages;
public function __construct(){
$this->messages = new ArrayCollection();
}
public function addMessage(Message $message){
$message->addUser($this);
$this->messages[] = $message;
}
}
消息.php
namespace Console\Entity;
use Doctrine\Common\Collections\ArrayCollection;
/**
* @Entity(repositoryClass="Console\Repository\Message")
* @Table(name="message")
*/
class Message {
/**
* @Id
* @GeneratedValue
* @Column(type="integer")
*/
protected $id;
/**
* @Column(type="text")
*/
protected $value;
/**
* @OneToMany(targetEntity="User", mappedBy="messages", cascade={"all"}, orphanRemoval=true)
* @JoinTable(name="user_message",
* joinColumns={@JoinColumn(name="user_id", referencedColumnName="id")},
* inverseJoinColumns={@JoinColumn(name="message_id", referencedColumnName="id", unique=true)}
* )
*/
protected $users;
public function __construct(){
$this->users = new ArrayCollection();
}
/**
* @param Console\Entity\User $user
*/
public function addUser(User $user){
$this->users[] = $user;
}
}
用户信息.php
namespace Console\Entity;
/**
* @Entity
* @Table(name="user_message")
*/
class UserMessage {
/**
* @Id
* @GeneratedValue
* @Column(type="integer")
*/
protected $id;
/**
* @Column(name="user_id", type="integer")
*/
protected $userId;
/**
* @Column(name="message_id", type="integer")
*/
protected $messageId;
/**
* @Column(name="is_read", type="boolean")
*/
protected $isRead;
public function isRead(){
return $this->isRead;
}
public function setIsRead($flag = true){
$this->isRead = (bool)$flag;
}
}
dump.sql(从学说生成)
dump.sql (generated from doctrine)
CREATE TABLE IF NOT EXISTS `message` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`type_id` int(11) DEFAULT NULL,
`value` longtext NOT NULL,
`created` datetime NOT NULL,
PRIMARY KEY (`id`),
KEY `IDX_B6BD307FC54C8C93` (`type_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=3 ;
CREATE TABLE IF NOT EXISTS `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ip_id` int(11) DEFAULT NULL,
`username` varchar(50) NOT NULL,
`password` varchar(64) NOT NULL,
`created` datetime NOT NULL,
`last_action` datetime DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `UNIQ_8D93D649F85E0677` (`username`),
UNIQUE KEY `UNIQ_8D93D649A03F5E9F` (`ip_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=2 ;
CREATE TABLE IF NOT EXISTS `user_message` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`message_id` int(11) NOT NULL,
`is_read` tinyint(1) NOT NULL,
`created` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
ALTER TABLE `message`
ADD CONSTRAINT `message_ibfk_1` FOREIGN KEY (`type_id`) REFERENCES `message_type` (`id`);
ALTER TABLE `user`
ADD CONSTRAINT `user_ibfk_1` FOREIGN KEY (`ip_id`) REFERENCES `ip` (`id`);
现在我的测试:
$user = $em->find('Console\Entity\User', 1);
$message = new Console\Entity\Message();
$message->setValue('TestNachricht');
$user->addMessage($message);
$em->persist($user);
$em->flush();
发生了什么:消息表已填，user_message 为空.我可以做什么来使用 user_message 表以及我必须做什么，将消息设置为已读"?
What's happen: message table is filled in, user_message is empty. What can I do to use the user_message table and what I have to do, to set en message as "read"?
