[英]ongr-io elasticsearch bundle implementation with doctrine symfony2
In our symfony2 project we want to implement elasticsearch with ongr-io bundle, but our whole system is built on doctrine. 在我们的symfony2项目中,我们希望使用ongr-io bundle实现elasticsearch,但我们的整个系统都是基于doctrine构建的。 Is it possible to somehow use ongr-io elasticsearch bundle without totally redoing whole database with documents instead of entities? 有可能以某种方式使用ongr-io elasticsearch bundle而不用文件而不是实体完全重做整个数据库吗?
Entity that I want to index (fields for search would be: name, ChildCategory and ParentCategory): 我想要索引的实体(搜索字段为:name,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;

it's very interesting. 这很有趣。
The first thing is Entity location. 第一件事是实体位置。 The document for ElasticsearchBundle has to be in Document
directory. ElasticsearchBundle的文档必须位于Document
目录中。 It's not a big deal. 没什么大不了的。 All you need to do is to create an empty class and extend entity with @Document
annotation. 您需要做的就是创建一个空类并使用@Document
注释扩展实体。 Next are the fields. 接下来是字段。 With name
field there is no problem at all, just add @property
annotation and you are good. 使用name
字段完全没有问题,只需添加@property
注释即可。 More interesting is with relations. 更有趣的是关系。 My suggestion would be to create separate property and in the getter return value from the relation for that field. 我的建议是创建单独的属性,并从该字段的关系中获取getter返回值。 I hope you got the idea. 我希望你有这个主意。
Update: 更新:
Here's an example of documents: 这是一个文件的例子:
AppBundle/Entity/Post 的appbundle /实体/后
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use ONGR\ElasticsearchBundle\Annotation as ES;
/**
* Post
*
* @ORM\Table(name="post")
* @ORM\Entity(repositoryClass="AppBundle\Repository\PostRepository")
*/
class Post
{
/**
* @var int
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @var string
*
* @ES\Property(type="string")
* @ORM\Column(name="title", type="string", length=255, nullable=true)
*/
private $title;
/**
* @var User
*
* @ORM\ManyToOne(targetEntity="User")
* @ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
/**
* @var string
*
* @ES\Property(name="user", type="string")
*/
private $esUser;
/**
* Get id
*
* @return int
*/
public function getId()
{
return $this->id;
}
/**
* Set title
*
* @param string $title
*
* @return Post
*/
public function setTitle($title)
{
$this->title = $title;
return $this;
}
/**
* Get title
*
* @return string
*/
public function getTitle()
{
return $this->title;
}
/**
* Set user
*
* @param \AppBundle\Entity\User $user
*
* @return Post
*/
public function setUser(\AppBundle\Entity\User $user = null)
{
$this->user = $user;
return $this;
}
/**
* Get user
*
* @return \AppBundle\Entity\User
*/
public function getUser()
{
return $this->user;
}
/**
* @return string
*/
public function getEsUser()
{
return $this->esUser;
}
/**
* @param string $esUser
*/
public function setEsUser($esUser)
{
$this->esUser = $esUser;
}
}
AppBundle/Document/Post 的appbundle /文件/后
<?php
namespace AppBundle\Document;
use ONGR\ElasticsearchBundle\Annotation as ES;
use AppBundle\Entity\Post as OldPost;
/**
* @ES\Document()
*/
class Post extends OldPost
{
}
