迁移到 FOSUserBundle

Question

到目前为止，我们一直在 Symfony2 中使用自定义身份验证系统。我们现在正在扩展我们的功能，它已经到了 FOSUserBundle 将节省时间的阶段。

我已经用 Composer 安装了 FOSUserBundle 并将其添加到 appKernel.php。

关于实体，由于已经有一个 User 实体，我刚刚删除了 FOS 包中 AbstractUser 实体已经具有的字段并对其进行了扩展：

use FOS\UserBundle\Entity\User as BaseUser;
...
class User extends BaseUser

我去用教义更新架构：schema:update --force 并得到以下内容：

  [Doctrine\DBAL\Schema\SchemaException]                 
  The table with name 'lifemirror.user' already exists. 

嗯，是的，用户表已经存在，但该命令应该更新它。我更改了用户实体中的表名并执行--dump-sql 以查看发生了什么，它似乎保留了表但删除了结构：

ALTER TABLE user DROP email, DROP username, DROP password, DROP invitation_code, DROP picture_file;

所以我认为 User 实体可能正在其他地方使用，但我不确定在哪里。

在 Pazi 的建议下，我安装了学说迁移包并尝试创建一个迁移。它生成以下内容

        $this->addSql("CREATE UNIQUE INDEX email ON user (email)");
        $this->addSql("ALTER TABLE video CHANGE timestamp timestamp DATETIME DEFAULT CURRENT_TIMESTAMP NOT NULL");
    }
}

我认为这突出了同样的问题 - 用户实体没有被正确扩展。

这就是为什么不建议将doctrine:schema:update 用于生产的原因。有一种更好更强大的方法：DoctrineMigrationsBundle。由于您的数据库发生了重大变化（即您的某些列只需要重命名，有些是新的，它们需要填充等）您应该自己处理它而不是自动处理它。通过 Doctrine Migrations，您可以以稳健的方式完成此步骤。您可以尝试从差异自动生成迁移类，但最后我认为您必须根据需要修改生成的类。我已经从一个全新的 symfony 安装中为您创建了一个迁移类，并使用了一个扩展 FOSUserBundle 基类的裸用户类（只有 id）。

<?php
// app/DoctrineMigrations/Version20130701120836.php

namespace Application\Migrations;

use Doctrine\DBAL\Migrations\AbstractMigration,
    Doctrine\DBAL\Schema\Schema;

/**
 * Auto-generated Migration: Please modify to your need!
 */
class Version20130701120836 extends AbstractMigration
{
    public function up(Schema $schema)
    {
        // this up() migration is autogenerated, please modify it to your needs
        $this->abortIf($this->connection->getDatabasePlatform()->getName() != "mysql");

        $this->addSql("CREATE TABLE fos_user (id INT AUTO_INCREMENT NOT NULL, username VARCHAR(255) NOT NULL, username_canonical VARCHAR(255) NOT NULL, email VARCHAR(255) NOT NULL, email_canonical VARCHAR(255) NOT NULL, enabled TINYINT(1) NOT NULL, salt VARCHAR(255) NOT NULL, password VARCHAR(255) NOT NULL, last_login DATETIME DEFAULT NULL, locked TINYINT(1) NOT NULL, expired TINYINT(1) NOT NULL, expires_at DATETIME DEFAULT NULL, confirmation_token VARCHAR(255) DEFAULT NULL, password_requested_at DATETIME DEFAULT NULL, roles LONGTEXT NOT NULL COMMENT '(DC2Type:array)', credentials_expired TINYINT(1) NOT NULL, credentials_expire_at DATETIME DEFAULT NULL, UNIQUE INDEX UNIQ_957A647992FC23A8 (username_canonical), UNIQUE INDEX UNIQ_957A6479A0D96FBF (email_canonical), PRIMARY KEY(id)) DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci ENGINE = InnoDB");

    }

    public function down(Schema $schema)
    {
        // this down() migration is autogenerated, please modify it to your needs
        $this->abortIf($this->connection->getDatabasePlatform()->getName() != "mysql");

        $this->addSql("DROP TABLE fos_user");
    }
}

现在您可以将 CREATE 语句修改为更改表，修改现有列并添加新列。然后，您需要第二条语句来更新这两个规范字段。它们只是原始列的小写版本。它们对于登录很重要。

与文档不同，如果您想保持最低稳定性以保持稳定，您需要在 composer.json 中使用这两行来安装它。

    "doctrine/migrations": "*@alpha",
    "doctrine/doctrine-migrations-bundle": "dev-master"

好的，已修复。我有一个扩展用户实体的注册实体，我在复制/粘贴后留下了一些“用户”注释，所以它认为有重复。我现在可以正常方式更新数据库了。
