php – Symfony2的Doctrine并没有为我创建一对多的结构

这些是表结构：

表用户

CREATE TABLE public.users (
  idx       bigint NOT NULL,"name"    varchar(250) DEFAULT NULL::character varying,surname   varchar(250) DEFAULT NULL::character varying,isactive  boolean NOT NULL DEFAULT false,/* Keys */
  CONSTRAINT users_pkey
    PRIMARY KEY (idx),CONSTRAINT users_idx_key
    UNIQUE (idx)
) WITH (
    OIDS = FALSE
  );

表数据：

CREATE TABLE public.datas (
  idx       bigint NOT NULL,useridx   bigint,phrase    varchar(100) DEFAULT NULL::character varying,response  varchar(100) DEFAULT NULL::character varying,/* Keys */
  CONSTRAINT datas_pkey
    PRIMARY KEY (idx),CONSTRAINT datas_idx_key
    UNIQUE (idx),/* Foreign keys */
  CONSTRAINT fk_cf180c1a262768b5
    FOREIGN KEY (useridx)
    REFERENCES public.users(idx)
    ON DELETE NO ACTION
    ON UPDATE NO ACTION
) WITH (
    OIDS = FALSE
  );

现在,当我运行这些命令：

app/console doctrine:mapping:convert yml
./src/Acme/DemoBundle/Resources/config/doctrine/metadata/orm
--from-database
--force

和;

app/console doctrine:mapping:import AcmeDemoBundle annotation
app/console doctrine:generate:entities AcmeDemoBundle

我得到了这个结果：

Datas.php
????

namespace AcmeDemoBundleEntity;

use DoctrineORMMapping as ORM;

/**
 * AcmeDemoBundleEntityDatas
 *
 * @ORMTable(name="datas")
 * @ORMEntity
 */
class Datas

    private $idx;

    /**

    private $phrase;

    /**

    private $response;

    }

    /**

    public function setPhrase($phrase)
    {
        $this->phrase = $phrase;
    }

    /**
     * Get phrase

    public function getPhrase()
    {
        return $this->phrase;
    }

    /**

    public function setResponse($response)
    {
        $this->response = $response;
    }

    /**

    public function getResponse()
    {
        return $this->response;
    }

    /**

     */
    public function setUseridx(AcmeDemoBundleEntityUsers $useridx)
    {
        $this->useridx = $useridx;
    }

    /**
     * Get useridx
     *
     * @return AcmeDemoBundleEntityUsers 
     */
    public function getUseridx()
    {
        return $this->useridx;
    }
}
?>

Users.php

<?php

namespace AcmeDemoBundleEntity;

use DoctrineORMMapping as ORM;
/**
 * AcmeDemoBundleEntityUsers
 *
 * @ORMTable(name="users")
 * @ORMEntity
 */
class Users
{
    /**

     * @ORMSequenceGenerator(sequenceName="users_idx_seq",initialValue="1")
     */
    private $idx;

    /**
     * @var string $name
     *
     * @ORMColumn(name="name",length=250,nullable=true)
     */
    private $name;

    /**
     * @var string $surname
     *
     * @ORMColumn(name="surname",nullable=true)
     */
    private $surname;

    /**
     * @var boolean $isactive
     *
     * @ORMColumn(name="isactive",type="boolean",nullable=false)
     */
    private $isactive;

    /**
     * Get idx
     *
     * @return bigint 
     */
    public function getIdx()
    {
        return $this->idx;
    }

    /**
     * Set name
     *
     * @param string $name
     */
    public function setName($name)
    {
        $this->name = $name;
    }

    /**
     * Get name
     *
     * @return string 
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Set surname
     *
     * @param string $surname
     */
    public function setSurname($surname)
    {
        $this->surname = $surname;
    }

    /**
     * Get surname
     *
     * @return string 
     */
    public function getSurname()
    {
        return $this->surname;
    }

    /**
     * Set isactive
     *
     * @param boolean $isactive
     */
    public function setIsactive($isactive)
    {
        $this->isactive = $isactive;
    }

    /**
     * Get isactive
     *
     * @return boolean 
     */
    public function getIsactive()
    {
        return $this->isactive;
    }
}
?>

我也有yml文件,但我不认为他们在这里只需要我发布的PHP文件.

现在,当我在我的控制器中运行此命令时：

<?php

$user = $this->getDoctrine()
->getRepository('AcmeDemoBundle:Users')
->find(24);

$phrase = $user->getDatas()->getPhrase();

?>

我得到一个错误,说在非对象上调用成员函数getDatas()….我知道它很清楚.在Users.php中,我没有getDatas().

但是我从Symfony2和Doctrine文档中读到的是它应该存在,因为它们是相关的.我想要做的就是在用户中获取数据.

这里我的错误是什么？什么我失踪了？

更新：
我将这些行添加到Users.php中

<?php
/**
     * @var AcmeDemoBundleEntityDatas
     *
     * @ORMOneToMany(targetEntity="Datas",mappedBy="datas",cascade={"all"})
     */
     private $datas;
public function __construct()
    {
        $this->datas = new DoctrineCommonCollectionsArrayCollection();
    }

    /**
     * Add phrases
     *
     * @param AcmeDemoBundleEntityDatas $datas
     */
    public function addPhrases(AcmeDemoBundleEntityDatas $datas)
    {
        $this->datas[] = $datas;
    }

    /**
     * Get datas
     *
     * @return DoctrineCommonCollectionsCollection 
     */
    public function getDatas()
    {
        return $this->datas;
    }
?>

这些行到Datas.php

<?php
/**
     * @ORMManyToOne(targetEntity="Users",inversedBy="users",cascade={"all"})
     */
    protected $users;
/**
     * Set users
     *
     * @param AcmeDemoBundleEntityUsers $users
     */
    public function setUsers(AcmeDemoBundleEntityUsers $users)
    {
        $this->users = $users;
    }

    /**
     * Get users
     *
     * @return AcmeDemoBundleEntityUsers 
     */
    public function getUsers()
    {
        return $this->users;
    }
?>

现在getDatas()正在工作,但内部却没有. ($用户> getDatas() – > getPhrase();)
我收到此错误：

Call to undefined method DoctrineORMPersistentCollection::getPhrase()

结论：我收到了错误,因为它返回了一个集合 – 当然 – .迭代(如foreach)它,你将访问数据. (如果遇到这样的问题.)
