Symfony2关系在子类中没有正确映射

Question

我的问题是:

我有一个抽象的类"物种"，我有另一个扩展物种的类"雷"。我在物种和类型之间有一个多对一的关系，因为每个物种都有一个类型。

当我使用doctrine生成数据库时，它生成了一个表species(很奇怪，因为它是抽象的)和一个表Raie。

为了避免生成物种表，我是否应该从实体定义中删除@ORMTable() ?这够吗?

主要问题是表Raie具有在species 中定义的所有属性，除了与typeSpecies实体的关系!

下面是我的两个类的定义来帮助你理解:

<?php
namespace AileronsBackendBundleEntity;
use DoctrineORMMapping as ORM;
use DoctrineCommonCollectionsArrayCollection;

Raie类

    <?php

class Raie extends Species

    * @ORMId
    * @ORMGeneratedValue(strategy="AUTO")

    private $id;
    /**
    * @var float
    *
    * @ORMColumn(name="wingspan", type="float")
    */
    private $wingspan;

    /**
    * Get id
    *
    * @return integer 
    */
    public function getId()
    {
       return $this->id;
    }
    /**
    * Set wingspan
    *
    * @param float $wingspan
    * @return Raie
    */
    public function setWingspan($wingspan)
    {
       $this->wingspan = $wingspan;
       return $this;
    }
    /**
    * Get wingspan
    *
    * @return float 
    */
    public function getWingspan()
    {
       return $this->wingspan;
    }
}

谢谢你的帮助

您可能需要更改抽象类的继承类型。在Doctrine文档
