无主键实体的 Symfony Doctrine 模型 [英] Symfony Doctrine Models for Entity Without Primary Keys

问题描述

我正在重新构建 Web 应用程序时使用旧数据库.我想使用 Symfony2.x，它显然将 Doctrine 作为 ORM.

I'm working with a legacy database while re-building the web application. I want to use Symfony2.x which obviously has Doctrine as ORM.

我有大约 50 个(mysql)表没有主键.当我尝试生成模型时，它不允许我这样做并抛出...表上没有主键"的异常.

I've around 50 (mysql) tables which has NO Primary Keys. When I try to generate models, it does not let me do and throw an exception with "No Primary Key on ... table".

我是否必须在表上有主键才能使用 Doctrine 或者有什么解决办法?

Do I must have Primary Keys on tables to use Doctrine or is there any way around it?

任何帮助都会很棒.

谢谢.

推荐答案

Doctrine 要求每个实体类都有一个标识符/主键.

Doctrine requires every entity class to have an identifier/primary key.

看看这个页面:http://www.doctrine-project.org/docs/orm/2.0/en/reference/basic-mapping.html#identifiers-primary-keys
