php - 使用学说 symfony2 实现 ongr-io elasticsearch 捆绑包

Question

在我们的 symfony2 项目中，我们想用 ongr-io 包实现弹性搜索，但是我们的整个系统是建立在教义上的。是否有可能以某种方式使用 ongr-io elasticsearch 包而不用文档而不是实体完全重做整个数据库？

我要索引的实体（搜索字段为：名称、ChildCategory 和 ParentCategory）：

/**
 * Course
 *
 * @ORM\Table(name="course")
 * @ORM\Entity(repositoryClass="CoreBundle\Repository\CourseRepository")
 * @ORM\HasLifecycleCallbacks
 */
    class Course
    {
        /**
         * @var int
         *
         * @ORM\Column(name="id", type="integer")
         * @ORM\Id
         * @ORM\GeneratedValue(strategy="AUTO")
         */
        private $id;

        /**
         * @var string
         *
         * @ORM\Column(name="name", type="string", length=255, unique=false)
         */
        private $name;

        /**
         * @var ParentCategory
         *
         * @ORM\ManyToOne(targetEntity="ParentCategory")
         * @ORM\JoinColumn(name="parentCategory_id", referencedColumnName="id")
         */
        private $parentCategory;

        /**
         * @var ChildCategory
         *
         * @ORM\ManyToOne(targetEntity="ChildCategory", inversedBy="courses")
         * @ORM\JoinColumn(name="childCategory_id", referencedColumnName="id")
         */
        private $childCategory;

        /**
         * @var City
         *
         * @ORM\ManyToOne(targetEntity="City")
         * @ORM\JoinColumn(name="city_id", referencedColumnName="id")
         */
        private $city;

        /**
         * @var Users
         *
         * @ORM\ManyToOne(targetEntity="UserBundle\Entity\Users", inversedBy="course")
         * @ORM\JoinColumn(name="owner_id", referencedColumnName="id")
         */
        private $owner;

        /**
         * @var text
         *
         * @ORM\Column(name="description", type="text")
         */
        private $description;

        /**
         * @var Picture
         *
         * @ORM\OneToMany(targetEntity="CoreBundle\Entity\Picture", mappedBy="course", cascade={"persist", "remove"})
         */
        private $pictures;

        /**
         * @var Ratings
         *
         * @ORM\OneToMany(targetEntity="CoreBundle\Entity\Ratings", mappedBy="courseid")
         */
        private $ratings;

        public $avgRating;
    }

这很有趣。

首先是实体位置。ElasticsearchBundle 的文档必须在Document目录中。没什么大不了的。您需要做的就是创建一个空类并使用@Document注释扩展实体。接下来是字段。有了name字段完全没有问题，只需添加@property注释就可以了。更有趣的是关系。我的建议是创建单独的属性，并在该字段的关系的 getter 返回值中。我希望你明白了。
