更新数据库架构时不允许使用空值

Question

我有一个名为 "FosUser" 的实体：

<?php

namespace techeventBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**

class FosUser

        private $prenom;

        private $tel;

        private $copon;


    }

我已经删除了这个实体中的字段并将字段的默认值更改为 null ('nullable = true')，如下所示：

<?php

namespace AppBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;

    protected $id;

    /**

    protected $nom;

    protected $prenom;

    protected $tel;

    /**

     */
    protected $age;

    /**

    protected $copon;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

我在更新数据库模式后遇到了这些错误：

In AbstractMySQLDriver.php line 112:

Answer 1

你的代码是正确的！之前你没有使用过 FOUser class，你的 fos_user table 已经有用户名，emailCanonical 等等... 然后，当您扩展 FOSUser 并更新数据库模式时，您当前的实体不接受用户名等的空值。（这是 FOSUser 逻辑）

解决方案，您必须在更新数据库模式之前删除 fos_user table

更新数据库架构时不允许使用空值

Null value not allowed while updating Database schema

php

mysql

doctrine

symfony
