Fos elastica在代码表中获取代码名称

Question

我正在使用fosElastica填充Elasticsearch。我有两个实体，那个实体关系在一起。

但是我无法在商品索引中填充和显示类别名称。我该怎么办？

Entity / AirportCodes.php

/**
 * @var string $AirportCode
 *
 * @ORM\Column(name="AirportCode", type="string", length=3)
 * @ORM\OneToOne(targetEntity="XXXBundle\Entity\AirportCodesTrans")
 * @ORM\JoinColumn(name="AirportCode", referencedColumnName="airport_code", nullable=false)
 */
private $airportCode;

Services.yml

example-connect:
    properties:
        AirportCode: { type: text, analyzer: autocomplete }
        AirportSlug: ~
        CountryCode: ~
        CityCode: ~
    persistence:
        driver: orm
        model: XXXBundle\Entity\AirportCodes
        identifier: AirportCode
        provider: ~
        finder: ~
