小编Tig*_*yan的帖子

试图将我的SQL查询转换为dql,似乎我做错了.

我需要基本的连接,就像这样.

SELECT a.id, a.title, u.name FROM articles JOIN users ON a.author_id = u.id

试着

SELECT a.id, a.title, u.name FROM Article a JOIN User u WITH a.author_id = u.id

得到错误

[Semantical Error] line 0, col 34 near 'Article a JOIN': Error: Class 'Article' is not defined.

我该如何定义？你能给我一个正确的解决方案吗？

文章实体

<?php

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="articles")
 */
class Article
{
    /**
     * @var integer $id
     *
     * @ORM\Id
     * @ORM\Column(name="id", type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected …

我正在尝试自己的身份验证类.

这是我的用户实体.

<?php
namespace AppBundle\Entity;

use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class User
{
    /**
     * @ORM\Column(type="int", length="11")
     */
    protected $id;

    /**
     * @ORM\Column(type="string", length="25")
     */
    protected $login;

    /**
     * @ORM\Column(type="string", length="25")
     */
    protected $password;

    /**
     * @ORM\Column(type="string", length="25")
     */
    protected $firstName;

    /**
     * @ORM\Column(type="string", length="25")
     */
    protected $lastName;

    /**
     * @ORM\Column(type="string", length="25")
     */
    protected $email;

    public function getId()
    {
    return $this->id;
    }

    public function getLogin()
    {
    return $this->login;
    }

    public function getPassword()
    {
    return $this->password; …

我正在尝试安装w .. 正如文档建议的那样,我使用pip安装wag:

Symfony 2 遇到一些问题。

尝试使用我的实体从表中获取一些行。

这是实体

namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

class Article
{

     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="string" name="title")
     */
    protected $title;


    /**
     * @ORM\Column(type="int" name="author_id")

    protected $authorId;

    protected $creationDate;

    protected $content;
