教义迁移，使用自定义教义类型的问题

本文介绍了教义迁移，使用自定义教义类型的问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 我正在使用Symfony2 + Doctrine2构建应用程序。我的应用程序需要存储地理空间数据，所以我写了适当的原则扩展。所有的工作都很好，应用程序已经在生产环境中运行了很长时间。

现在我必须添加一些新功能，我需要更新数据库而不删除所有的数据。我想了解使用DoctrineMigrationBundle，但是当我运行时：

$ php app / console doctrine：migrations：status

我收到此错误：

[Doctrine\DBAL\DBALException] 未知的数据库类型请求点， Doctrine\DBAL\Platforms\MySqlPlatform可能不支持。

这是我config.yml的相关部分：

＃Doctrine配置 doctrine： dbal：驱动程序：％database_driver％主机：％database_host％ port：％database_port％ dbname：％database_name％用户：％database_user％密码：％database_password％字符集：UTF8 类型：点：App \EngineBundle\DoctrineExtensions\PointType

自定义类型点已被映射那么我做错了什么？

解决方案

我回答自己的问题，似乎问题是DoctrineMigrations还需要一个映射自定义类型。所以config.yml应该如下所示：

＃Doctrine Configuration doctrine： dbal：驱动程序：％database_driver％主机：％database_host％端口：％database_port％ dbname：％database_name％用户：％database_user％密码： ％database_password％字符集：UTF8 类型：点：App \EngineBundle\DoctrineExtensions\PointType mapping_types：点：点

I'm building a application using Symfony2 + Doctrine2. My application needs to store geospatial data, so I wrote the proper doctrine extensions. All is working pretty good and the app have been running in a production enviroment for a long time.

Now I have to add some new features and I need to update the database without deleting all the data. I thougth about using the DoctrineMigrationBundle but when I run:

$ php app/console doctrine:migrations:status

I got this error:

[Doctrine\DBAL\DBALException] Unknown database type point requested, Doctrine\DBAL\Platforms\MySqlPlatform may not support it.

This is the relevant section of my config.yml:

# Doctrine Configuration doctrine: dbal: driver: %database_driver% host: %database_host% port: %database_port% dbname: %database_name% user: %database_user% password: %database_password% charset: UTF8 types: point: App\EngineBundle\DoctrineExtensions\PointType

The custom type 'point' has been mapped, so what am I doing wrong?

解决方案

I answer my own question, it seems the problem is DoctrineMigrations also needs a mapping for the custom type. So the config.yml should look like this:

# Doctrine Configuration doctrine: dbal: driver: %database_driver% host: %database_host% port: %database_port% dbname: %database_name% user: %database_user% password: %database_password% charset: UTF8 types: point: App\EngineBundle\DoctrineExtensions\PointType mapping_types: point: point
