教义2不能使“2”一对多的关系

本文介绍了教义2不能使“2”一对多的关系的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

项目一对多，我试图使3个实体（项目，同意，不同意）同意

项目一对多不同意

但只有一个关系（稍后声明）

Here're我的.yml文件。

  Entities\Item：
 type：entity 
 fields：
 id：
 type：integer 
 id ：true 
生成器：
策略：AUTO 
 oneToMany：
同意：
 targetEntity：Agree 
 mappedBy：items 
 oneToMany：
不同意：
 targetEntity：不同意
 mappedBy：items

 实体\Agree：
类型：实体
字段：
 id：
类型：整数
 id：true 
生成器：
策略：AUTO 
 manyToOne：
 items：
 targetEntity：Item 
 inversedBy：agrees

  Entities\Disagree：
 type：entity 
 fields：
 id：
 type：integer 
 id：true 
生成器：
策略：AUTO 
 manyToOne：
 items：
 targetEntity：Item 
 inversedBy：disagrees

下面的代码是由Doctrine2自动生成的Item.php。您可以看到，它不包含同意。

 命名空间实体; 
 
 class Item {
 private $ id; 
 private $ disagrees; 
 
 public function __construct（）{
 $ this-> disagrees = new \Doctrine\Common\Collections\ArrayCollection（）; 
} 
 
 public function getId（）{
 return $ this-> id; 
} 
 
 public function addDisagrees（\Entities\Disagree $ disagrees）{
 $ this-> disagrees [] = $ disagrees; 
} 
 
 public function getDisagrees（）{
 return $ this-> disagrees; 
} 
}

如果我转换声明顺序（不同意，后跟Agree，如下所示），Item.php此时只有同意相关的代码。

 实体\Item：
类型：实体
字段：
 id：
类型：整数
 id：true 
生成器：
策略：AUTO 
 oneToMany：
不同意：
 targetEntity：不同意
 mappedBy：items 
 oneToMany：
同意：
 targetEntity：Agree 
 mappedBy：items

我的代码有什么问题？任何意见都将有所帮助。

项目，同意和不同意只是显示此问题的示例。在实际项目中，同意和不同意是完全不同的实体。所以，不要建议我把它们合并成统一的实体。：）

解决方案

你很亲密，只需要把所有相同的关联映射类型放在相同的类型声明下:) p>

  oneToMany：
同意：
 targetEntity：Agree 
 mappedBy：items 
不同意： 
 targetEntity：不同意
 mappedBy：items

I'm trying to make 3 entities (Item, Agree, Disagree) with following relations.

Item one-to-many Agree
Item one-to-many Disagree

But only one relation (declared later) out of two has made.

Here're my .yml files.

Entities\Item:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
  oneToMany:
    agrees:
      targetEntity: Agree
      mappedBy: items
  oneToMany:
    disagrees:
      targetEntity: Disagree
      mappedBy: items

Entities\Agree:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
  manyToOne:
    items:
      targetEntity: Item
      inversedBy: agrees

Entities\Disagree:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
  manyToOne:
    items:
      targetEntity: Item
      inversedBy: disagrees

And the code below is the Item.php auto-generated by Doctrine2. As you can see, it doesn't contains 'Agree' at all.

namespace Entities;

class Item {
    private $id;
    private $disagrees;

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

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

    public function addDisagrees(\Entities\Disagree $disagrees) {
        $this->disagrees[] = $disagrees;
    }

    public function getDisagrees() {
        return $this->disagrees;
    }
}

If I switches the declaration order ('Disagree' first, followed by'Agree', like the below), Item.php has only 'Agree'-related code in this time.

Entities\Item:
  type: entity
  fields:
    id:
      type: integer
      id: true
      generator:
        strategy: AUTO
  oneToMany:
    disagrees:
      targetEntity: Disagree
      mappedBy: items
  oneToMany:
    agrees:
      targetEntity: Agree
      mappedBy: items

What's wrong with my code? Any comments will be helpful.

Item, Agree and Disagree are just samples to show this problem. In real project, Agree and Disagrees are totally different entity. So, don't suggest me to merge them into unified entity. :)

解决方案

You were close, you just need to put all same association mapping types under the same type declaration :)

  oneToMany:
    agrees:
      targetEntity: Agree
      mappedBy: items
    disagrees:
      targetEntity: Disagree
      mappedBy: items
