【问题描述】：

我已经使用我的数据库一个月了。突然我开始得到错误：

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

，加载夹具时。最后，我删除了所有数据库，重新运行迁移，只留下了 1 个夹具文件（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\Entity\User.php

..
/**

 * @ORM\Table(name="tuser")

class User implements AdvancedUserInterface, \Serializable
..
    /**
     * @var string

    private $username;

    /**

    private $isActive;

    /**

     *
     * @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，但布尔 IsActive 的 tinyint 除外。只有一个表有名称用户。

【问题讨论】：

在 25 个问题中，您还没有接受一个答案。奇怪。

我再次删除了所有数据库和所有迁移 - 也许原因是我有旧的迁移。从零开始重新生成所有内容，为表提供自定义名称。清除缓存。但比我尝试加载用户设备时，我得到了错误：[Symfony\Component\Debug\Exception\ContextErrorException] 注意：数组到字符串的转换

当我更新作曲家时。

最后我创建了一个新项目，新数据库，新包，复制实体，重新运行迁移。但比我尝试运行固定装置时，我得到了同样的错误：为表设置自定义名称。清除缓存。但比我尝试加载用户设备时，我得到了错误：[Symfony\Component\Debug\Exception\ContextErrorException] 注意：数组到字符串的转换

你可能错过了我评论的重点。到目前为止，您已经发布了几十个问题。其中没有一个得到您满意的答复。您为什么认为有人会花时间尝试回答这个问题？问题当然是网页数组不能为空，但告诉你真的没有意义。

【参考方案1】：

问题在于角色字段，我昨天晚上将其更改为字符串而不是数组。但我忘记删除初始化 $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”并检查分配变量是否应该等于数组等。

这是我第四次因为简单的错误重做所有项目。结论是，最好继续思考哪里可能是错误的。另一方面，当学说没有产生杂物时，用不同的 Symfony 版本重新安装项目会有所帮助。 私人$角色； // = 数组();
