主义双向多对多

我在“组”和“检查”之间具有双向多对多关系。主义双向多对多

数据库表：

+--------------------+ 
| GROUP    | 
+--------------------+ 
| id    | 
| name    | 
| next    | 
+--------------------+ 

+--------------------+ 
| CHECKFOR   | 
+--------------------+ 
| group    | 
| check    | 
+--------------------+ 

+--------------------+ 
| CHECK    | 
+--------------------+ 
| id    | 
| description  | 
| author   | 
+--------------------+

Symfony的学说实体

集团

<?php 
class Group implements GroupInterface 
{ 
    /** 
    * @var integer 
    * 
    * @ORM\Column(name="id", type="integer") 
    * @ORM\Id 
    * @ORM\GeneratedValue(strategy="AUTO") 
    */ 
    private $id; 

    /** 
    * @var string 
    * @ORM\Column(name="name", type="string", length=32, nullable=false) 
    */ 
    private $name; 

    /** 
    * @ORM\OneToOne(targetEntity="Group") 
    * @ORM\JoinColumn(name="next", referencedColumnName="id") 
    * @Serializer\Exclude 
    */ 
    private $next; 

    /** 
    * @ORM\OneToMany(targetEntity="CheckFor", mappedBy="group") 
    */ 
    private $checks; 

    ... 

}

检查

<?php 
class Check implements CheckInterface 
{ 
    /** 
    * @var integer 
    * 
    * @ORM\Column(name="id", type="integer") 
    * @ORM\Id 
    * @ORM\GeneratedValue(strategy="AUTO") 
    */ 
    private $id; 

    /** 
    * @var string 
    * @ORM\Column(name="description", type="string", length=256) 
    */ 
    private $description; 

    /** 
    * @ORM\ManyToOne(targetEntity="\Jds\UserBundle\Entity\User") 
    * @ORM\JoinColumn(name="madeByUser", referencedColumnName="id") 
    * @Serializer\Exclude 
    */ 
    private $author; 

    /** 
    * @var string 
    * @ORM\Column(name="kind", type="string", length=20) 
    */ 
    private $kind; 

    /** 
    * @ORM\OneToMany(targetEntity="CheckFor", mappedBy="group") 
    */ 
    private $groups; 

}

checkfor

class CheckFor implements CheckForInterface 
{ 
    /** 
    * @ORM\ManyToOne(targetEntity="Check") 
    * @ORM\JoinColumn(name="check", referencedColumnName="id") 
    * @ORM\Id 
    */ 
    private $check; 

    /** 
    * @ORM\ManyToOne(targetEntity="Group") 
    * @ORM\JoinColumn(name="group", referencedColumnName="id") 
    * @ORM\Id 
    */ 
    private $group; 

    ... 
}

在运行时，一个无限循环通过..->repository->findBy()创建。如何防止这个'错误'？

更新3：我已经找到了问题！ '检查'是一个持久性收集，而不是一个数组收藏。持久收集对于JMS序列化程序不起作用。当我打印组对象的转储时，我在dev_log（= correct）中看到2个查询。当我用序列化程序解析对象时，我看到+10个查询（=不好）。

我已经搜索了一个解决方案，并试图禁用lazyloading但这并没有解决问题。

您是否尝试过按照页面一个接一个的例子吗？摆脱联接列，只需添加联接表并为其命名即可。另外一定要有构造函数 – Koalabaerchen 2014-12-09 14:41:07

同样的问题，以及如何设置列名不同于默认值：“entity_id”。我已经改变了我的测试列名。 – jsprds 2014-12-09 14:51:50

ManyToMany主义实际存在，所以你不需要创建第三个实体。它会自动创建。

关键字这是@ORM \ JoinTable

同样的问题： /** * @ORM \多对多（targetEntity = “组”，inversedBy = “检查”） * @ORM \ JoinTable（名称= “checkfor”， * joinColumns = {@ ORM \ JoinColumn （name =“group”，referencedColumnName =“id”）}， * **/ 私人$团体; /** * @ORM \多对多（targetEntity = “检查”，的mappedBy = “组”） * @ORM \ JoinColumn（名称= “检查”，referencedColumnName = “集团”） **/ 私人$检查; – jsprds 2014-12-09 14:04:21

你能更新你的问题吗？更易于阅读:) – Koalabaerchen 2014-12-09 14:27:23

oops抱歉。更新了我的帖子。 – jsprds 2014-12-09 14:33:18
