Symfony/Doctrine：ManyToMany關係和SQL異常

Question

我在Symfony應用程序中定義了「實體幻燈片」和「幻燈片」之間的ManyToMany關係。

實體幻燈片（節選）：

use Doctrine\ORM\Mapping as ORM; 

/** 
* @ORM\Entity 
* @ORM\Table(name="slide") 
*/ 
class Slide { 

/* [...] */ 

/** 
* @ORM\ManyToMany(targetEntity="Slideshow", inversedBy="slides", cascade={"persist"}) 
* @ORM\JoinTable(name="slides_to_slideshows", 
*  joinColumns={@ORM\JoinColumn(name="slide_id", referencedColumnName="id")}, 
*  inverseJoinColumns={@ORM\JoinColumn(name="slideshow_id", referencedColumnName="id")} 
*  ) 
*/ 
private $slideshows; 


/** 
* Constructor 
*/ 
public function __construct() 
{ 
    $this->slideArticle = new \Doctrine\Common\Collections\ArrayCollection(); 
    $this->slideshows = new \Doctrine\Common\Collections\ArrayCollection(); 
} 


/* [...] */ 

/** 
* Add slideshow 
* 
* @param Slideshow $slideshow 
* 
* @return Slide 
*/ 
public function addSlideshow(Slideshow $slideshow) 
{ 
    $this->slideshow[] = $slideshow; 

    return $this; 
} 

/** 
* Get slideshows 
* 
* @return \Doctrine\Common\Collections\Collection 
*/ 
public function getSlideshows() 
{ 
    return $this->slideshows; 
} 

/** 
* Remove slideshow 
* 
* @param Slideshow $slideshow 
*/ 
public function removeSlideshow(Slideshow $slideshow) 
{ 
    $this->slideshows->removeElement($slideshow); 
} 
} 

實體幻燈片（節選）：

/** 
* @ORM\Entity 
* @ORM\Table(name="slideshow") 
*/ 
class Slideshow { 

/* [...] */ 


    /** 
    * @ORM\ManyToMany(targetEntity="Slide", mappedBy="slideshows") 
    */ 
    private $slides;   

    /** 
    * Constructor 
    */ 
    public function __construct() 
    { 
     $this->slides = new \Doctrine\Common\Collections\ArrayCollection(); 
    } 

/* [...] */ 

    /** 
    * Get slides 
    * 
    * @return \Doctrine\Common\Collections\Collection 
    */ 
    public function getSlides() 
    { 
     return $this->slides; 
    } 

    /** 
    * Add slide 
    * 
    * @param \Screensolutions\Macms\FrontBundle\Entity\Slide $slide 
    * 
    * @return Slideshow 
    */ 
    public function addSlide(\Screensolutions\Macms\FrontBundle\Entity\Slide $slide) 
    { 
     $this->slides[] = $slide; 

     return $this; 
    } 

    /** 
    * Remove slide 
    * 
    * @param \Screensolutions\Macms\FrontBundle\Entity\Slide $slide 
    */ 
    public function removeSlide(\Screensolutions\Macms\FrontBundle\Entity\Slide $slide) 
    { 
     $this->slides->removeElement($slide); 
    } 
} 

當我做一個數據庫查詢，我得到這個錯誤信息：

An exception occurred while executing 'SELECT t0.id AS id_1, t0.deleted AS deleted_2, t0.title AS title_3, t0.link AS link_4, t0.rank AS rank_5, t0.artist_id AS artist_id_6 FROM slide t0 WHERE slides_to_slideshows.slideshow_id = ? ORDER BY t0.deleted ASC, t0.rank ASC, t0.title ASC' with params ["2"]:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'slides_to_slideshows.slideshow_id' in 'where clause'

t能夠slides_to_slideshows存在，字段slideshow_id以及，所以我想我的關係的定義是錯誤的。我想知道爲什麼查詢是slides_to_slideshows.slideshow_id而不是FROM slide t0，slides_to_slideshows t1 WHERE t1.slideshow_id？

任何提示？

問候

編輯： 這是一個查詢挑起的錯誤：

$repository = $this->getDoctrine()->getRepository('FrontBundle:Slide'); 
$slidesAll = $repository->findBy(array('slideshows' => $id), array('deleted' => 'ASC', 'rank' => 'ASC', 'title' => 'ASC')); 

正如CERAD建議我做了一個試驗用一個簡單的findAll（）查詢和作品完美無瑕的。問題在於where條款'slideshows'=> $ id，所以我認爲關係的定義有些問題。模式：

緩存被清除至少有一千次，數據庫由學說更新更新--force和學說：架構：驗證不報告該實體的任何問題。

有什麼建議嗎？我很感激每一個暗示 - 這個問題讓我瘋狂:(

Answer 1

你應該做這樣的事情

$repository = $this->getDoctrine()->getRepository('FrontBundle:Slide')->createQueryBuilder('s') 
->join('s.slideshows', 'sw') 
->andWhere('sw.id=:id')->setParameter('id', $id) 
->addOrderBy('s.deleted', 'ASC') 
...
