doctrine复合主键迁移

Question

1. 我的Symfony项目中有一个带有复合主键的Doctrine实体：

  var onTap = function(marker) {
    console.log("Marker tapped with title: '" + marker.title + "'");
  };
  var onCalloutTap = function(marker) {
    alert("Marker callout tapped with title: '" + marker.title + "'");
  };

  mapbox.addMarkers([
    {
      id: 2, // can be user in 'removeMarkers()'
      lat: 52.3602160, // mandatory
      lng: 4.8891680, // mandatory
      title: 'One-line title here', // no popup unless set
      subtitle: 'Infamous subtitle!',
      icon: 'res://cool_marker', // preferred way, otherwise use:
      icon: 'http(s)://website/coolimage.png', // from the internet (see the note at the bottom of this readme), or:
      iconPath: 'res/markers/home_marker.png',
      onTap: onTap,
      onCalloutTap: onCalloutTap
    },
    {
      ..
    }
  ])

1. 运行/** * @ORM\Entity * @ORM\Table(name="`content_article_serie_reference`") */ class ArticleSerieReference { /** * @ORM\Id * @ORM\ManyToOne(targetEntity="Article", inversedBy="series") * @ORM\JoinColumn(name="article", referencedColumnName="id") */ protected $article; /** * @ORM\Id * @ORM\ManyToOne(targetEntity="Serie") * @ORM\JoinColumn(name="serie", referencedColumnName="id") */ protected $serie; 以创建迁移
2. Doctrine为MySQL数据库创建PRIMARY KEY（文章，系列），INDEX（文章），INDEX（serie）。

有没有办法告诉Doctrine不要创建这个无用的“文章”索引？
