教义ODM @yaml中的距离

Question

如何在Yaml映射文件中添加@Distance？ 我试过了，没有用。

CP\AppBundle\Document\Point:
  type: embeddedDocument
  embedOne:
    address:
      targetDocument: CP\AppBundle\Document\Address
    coordinates:
      targetDocument: CP\AppBundle\Document\Coordinates
  distance: distance
  indexes:
    coordinates:
      keys:
        coordinates: 2d

非常感谢！

距离字段需要指定为带有距离参数的浮点数：

CP\AppBundle\Document\Point:
  type: embeddedDocument
  embedOne:
    address:
      targetDocument: CP\AppBundle\Document\Address
    coordinates:
      targetDocument: CP\AppBundle\Document\Coordinates
  fields:
    distance:
      type: float
      distance: true
  indexes:
    coordinates:
      keys:
        coordinates: 2d
