Symfony2，Doctrine，fixture，Array to string conversion

标签： symfony doctrine-orm fixtures

我正在使用我的数据库一个月。突然间我开始收到错误：

[Symfony\Component\Debug\Exception\ContextErrorException]
 Notice: Array to string conversion

，装载灯具时。最后，我删除了所有数据库，重新运行迁移，只剩下1个fixtures文件（因此我评论了我们的OrderedFIxturesInterface，当然我清除了缓存，但错误仍然存​​在）。  C：\ Bitnami \ wampstack-5.5.30-0 \ sym_prog \ proj2_27 \ SRC \ MeetingBundle \ DataFixtures \ ORM \ LoadUsers01.php 

<?php

namespace MeetingBundle\DataFixtures\ORM;

use Doctrine\Common\DataFixtures\FixtureInterface;
use Doctrine\Common\Persistence\ObjectManager;
use MeetingBundle\Entity\User;
use Doctrine\Common\DataFixtures\AbstractFixture;
use Doctrine\Common\DataFixtures\OrderedFixtureInterface; 

class LoadUsers01 extends AbstractFixture 
#implements OrderedFixtureInterface
{
    public function load(ObjectManager $manager)
    {
        for ($i = 1; $i <= 10; $i++) {
            $fuser = new User();
            $fuser->setUsername('name'.$i);
            $fuser->setEmail('g.statkute'.$i.'@gmail.com');
            $fuser->setIsActive(True); // i also used 1
            $fuser->setPassword('pswd'.$i);
            $manager->persist($fuser);
           # $this->addReference('fuser:name'.$i, $fuser);
        }

        $manager->flush();
    }

        public function getOrder()
    {
        return 1;
    }
}

。

C：\ Bitnami \ wampstack-5.5.30-0 \ sym_prog \ proj2_27 \ SRC \ MeetingBundle \实体\ user.php的

..
/**
 * User
 *
 * @ORM\Table(name="tuser")
 * @ORM\Entity()
 */
class User implements AdvancedUserInterface, \Serializable
..
    /**
     * @var string
     *
     * @ORM\Column(name="username", type="string", length=255, unique=true)
     */
    private $username;

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

    /**
     * @var bool
     *
     * @ORM\Column(name="is_active", type="boolean")
     */
    private $isActive;

    /**
     * @var string
     *
     * @ORM\Column(name="password", type="string", length=255, unique=true)
     */
    private $password;

..

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

        return $this;
    }
   /**
     * @param string $email
     * @return User
     */
    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**
     * @param boolean $isActive
     */
    public function setIsActive($isActive)
    {
        $this->isActive = $isActive;
    }

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

        return $this;
    }

表包含varchar字段，除了tinyint for boolean IsActive。只有一个包含名称用户的表格。

答案 0 :(得分：0)

问题在于角色字段，我昨天晚上改为字符串而不是数组。但我忘了删除初始化$ roles = array（）; 

/**
 * @var string
 *
 * @ORM\Column(name="roles", type="string", nullable=true)
 */
private $roles; // it was $roles= array();

因此，如果您看到此错误，请在相关文件中搜索关键字“array”，并检查assign variable是否应该等于数组等。

这是我第四次因为简单的错误而重做所有项目。结论是，更好地继续思考哪里可能是一个错误。另一方面，当学说没有产生问题时，用不同的Symfony版本重新安装项目会有所帮助。     私人$角色; // = array（）;
