我是 Doctrine 的新手，我正在尝试制作 MongoDb 模型/集合。我有一个字段languages，它应该是数组。像这样的数组:
$var = [
array("fname"=>"test","lname"=>"test"),
array("fname"=>"test","lname"=>"test"),
array("fname"=>"test","lname"=>"test"),
];
但是我的类型声明似乎不起作用。我有:
<?php
namespace RemoteStaff\Documents;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ODM\MongoDB\Mapping\Annotations as ODM;
/**
* Class CandidateAsl
* @package RemoteStaff\Documents
* @ODM\Document(db="prod", collection="candidates_asl")
*/
class CandidateAsl
{
/**
* Constructor class
*/
public function __construct(){
$this->languages = new ArrayCollection();
}
/**
* @var String
* @ODM\Id(strategy="AUTO", type="string")
*/
protected $_id;
/**
* @var string
* @ODM\Field(type="string", name="gender")
*/
private $gender;
/**
* @var \DateTime
* @ODM\Field(type="date", name="birthdate")
*/
private $birthdate;
/**
* @var string
* @ODM\Field(type="string", name="nationality")
*/
private $nationality;
/**
* @var string
* @ODM\Field(type="string", name="permanentAddress")
*/
private $permanentAddress;
/**
* @var \Doctrine\Common\Collections\ArrayCollection
*/
private $languages = [];
}
如何在 Doctrine 模型中声明或设置数组字段？
我已阅读文档 http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/basic-mapping.html并尝试过
/**
* @var array
* @ODM\Field(type="array", name="languages")
*/
private $languages = [];
/**
* @return mixed
*/
public function getLanguages()
{
return $this->languages;
}
/**
* @param mixed $languages
*/
public function setLanguages($languages)
{
$this->languages = $languages;
}
我收到指定的“数组”类型无效。
最佳答案
MongoDB ODM 不支持数组字段类型。请改用 hash 或 collection。
来自documentation :
collection: numerically indexed array to MongoDB array
hash: associative array to MongoDB object
关于php - Doctrine 模型数组数据类型，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41629359/
