如何正确构建有关实体的Doctrine请求。大家好日子。我对Symfony没什么问题。

$repository = $this->getDoctrine()->getRepository('enterBundle\Entity\users');

                    $query=$repository->createQueryBuilder('user')
                            ->select('user.id','user.username','user.password','user.token')
                            ->where('user.username=:userName')->setParameter('userName',$login)
                            ->where('user.password=:Pass')->setParameter('Pass',$password)
                            ->getQuery
                            ->getResult(Query::HYDRATE_ARRAY);

问题是＆＃34;如何修复高级代码＆＃34;？

注意：未定义的属性：Doctrine \ ORM \ QueryBuilder :: $ getQuery

                            ->getResult(Query::HYDRATE_ARRAY);

实体：

<?php

namespace enterBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * users
 *
 * @ORM\Table(name="users")
 * @ORM\Entity(repositoryClass="enterBundle\Repository\usersRepository")
 */
class users
{
    /**
     * @var int
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;




    /**
     * @var string
     *
     * @ORM\Column(name="username", type="string", length=777,  unique=true)
     */
    private $username;

    /**
     * @var string
     *
     * @ORM\Column(name="password", type="string", length=999)
     */
    private $password;

    /**
     * @var string
     *
     * @ORM\Column(name="token", type="text")
     */
    private $token;


    /**
     * Get id
     *
     * @return int
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set username
     *
     * @param string $username
     *
     * @return users
     */
    public function setUsername($username)
    {
        $this->username = $username;

        return $this;
    }

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


    /**
     * Set password
     *
     * @param string $password
     *
     * @return users
     */
    public function setPassword($password)
    {
        $this->password = $password;

        return $this;
    }

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

    /**
     * Set token
     *
     * @param string $token
     *
     * @return users
     */
    public function setToken($token)
    {
        $this->token = $token;

        return $this;
    }

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

问题是如何正确使用createQueryBuilder？ 附：我是symfony的新手

Answer 1

注意：未定义的属性：Doctrine \ ORM \ QueryBuilder :: $ getQuery

在这里查看代码：

//...
->getQuery  // <--- missing ()
->getResult(Query::HYDRATE_ARRAY);

问题是如何正确使用createQueryBuilder？

最佳实践建议在存储库方法中创建此逻辑。

首先，创建用户存储库类：

// src/AppBundle/Repository/UserRepository.php

class UserRepository extends EntityRepository
{
    public function findUser($username, $password)
    {
        return $this->createQueryBuilder('user')
                   ->select('user.id','user.username','user.password','user.token')
                   ->where('user.username = :username')->setParameter('username', $username)
                   ->andWhere('user.password = :pass')->setParameter('pass', $password)
                   ->getQuery()
                   ->getArrayResult();
    }
}

请注意第二个where语句，必须考虑andWhere或orWhere，否则将替换第一个where语句。

其次，将您的存储库与您的实体相关联：

/**
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="AppBundle\Repository\UserRepository")
 */
class User
{
    //...
}
