添加新索引

Question

我有2个问题。我不确定我们是否可以为2个问题创建一个线程，所以请告诉我。

添加新索引

我要为性能添加新索引，但它会创建一个新表用户带有新索引

我的代码：

 * User
 *
 * @ORM\Table(name="fos_user")
 * @ORM\Table(indexes={@ORM\Index(name="last_activity_idx", columns={"last_activity"})})
 * @ORM\Table(indexes={@ORM\Index(name="avatar_idx", columns={"avatar"})})

所以我想，我必须在一个@ORM \ Table中列出所有索引。但是怎么样？

我尝试更新

时出错

当我尝试 - 强制执行此错误时：

（抱歉长篇文章）

我知道它想要删除所有索引并重新创建所有索引。但是我没有删除像user_id FK这样的学说创建的默认索引，我juste想要添加一些因为我的网站很慢。我完全失去了......

通常，您的方法是有效的。具有FK约束的事情是，Doctrine有时无法自行解决它们。

您必须打开MySQL shell并首先停用FK检查：

SET FOREIGN_KEY_CHECKS = 0;

然后你必须将app/console doctrine:schema:update --dump-sql --complete的输出发布到同一个MySQL shell中。

这应该应用所有挂起的更新（希望）没有问题。提示：连接所有行，以便在出现警告或错误时快速查看。

之后，您可以关闭shell并再次运行app/console doctrine:schema:update --dump-sql --complete，以查看您的数据库现在是否与架构同步。
