问题描述

我正在使用odm mongo原则,而我必须使用文档类

I'm using odm mongo doctrine and I have to document-classes

class Thing
{
/**
 * @MongoDB\Id
 */
protected $id;

 /**
  * @MongoDB\ReferenceOne(targetDocument="Bundle1:Other")
  */
protected $other;
}

class Other
{
/**
 * @MongoDB\Id
 */
protected $id;
}

所以在数据库中,一个东西看起来像:

so in the database a thing looks like :

{
  "_id":ObjectId("43z758634875adf"),
  "other":ObjectId("38z287348d8se")
}

我现在如何查询其他是给定ID的内容?

How can I now query for things where other is a given id ?

    $dm=$this->mongo->getManager();
            $answers=$dm
                ->createQueryBuilder('Bundle1:Thing')
                ->field('other')->equals("ObjectId(516c0061975a299edc44b419)")  // <-- ?
                ->getQuery()
                ->execute()->count();       

这会产生错误的mongo查询

This produces a wrong mongo query


MongoDB查询:
{find:true,query:{other:ObjectId(516c0061975a299edc44b419)},fields:[],db maself,collection:thing}
[] []

MongoDB query: {"find":true,"query":{"other":"ObjectId(516c0061975a299edc44b419)"},"fields":[],"db":"maself","collection":"thing"} [] []

当我使用


- > field('other') - > equals(516c0061975a299edc44b419)

->field('other')->equals("516c0061975a299edc44b419")

查询也是错误的


MongoDB查询:
{find:true,query :{other:516c0061975a299edc44b419},fields:[],db:maself,collection:thing}
[] []

MongoDB query: {"find":true,"query":{"other":"516c0061975a299edc44b419"},"fields":[],"db":"maself","collection":"thing"} [] []

那么如何搜索其他id等于objectId的东西?

So how can I search for thing where other id equals an objectId ?

推荐答案

尝试

->field('other')->equals(new \MongoId("516c0061975a299edc44b419"))

ObjectId是Mongo的内部类型,由PHP中的\MongoId()表示)

ObjectId is the internal type for Mongo, represented by \MongoId() in PHP

(但我也在第一个主题中回答)

( But i have also answered in the first topic )
