Symfony Doctrine迁移，我如何使用多个实体管理器 [英] Symfony Doctrine Migrations, how can I use multiple entity managers

问题描述

使用Symfony 2.5和Doctrine 2.2，我有几个数据库用于我正在处理的应用程序，让我们称之为主和另一个辅助。目前已经配置了两个实体管理器。在一次迁移中，我想在Secondary中创建一个表，但它只是要在Main中创建表。

Using Symfony 2.5 and Doctrine 2.2, I have several databases for an application I'm working on, let's call one "Main" and the other "Secondary". There are currently two entity managers configured. In one migration I want to create a table in "Secondary" but it only wants to create the table in "Main."

迁移可以是ContainerAware，所以我可以得到另一个EntityManager，但是我一直无法覆盖默认的EntityManager。有能力帮忙吗？感谢提前！

A migration can be ContainerAware, so I can get another EntityManager, but I have been unable to override the default one. Any able to help? Thanks in advance!

推荐答案

生成时只需通过 - em 参数 DIFF 。

Just pass --em parameter when generating diff.

示例：

php app/console doctrine:migrations:diff --em=uac # will use uac entity manager
php app/console doctrine:migrations:diff # will use the default entity manager

要排除自定义表格以免删除使用：

To exclude custom tables from removal use:

doctrine:
    dbal:
        schema_filter: ~^(?!t_)~

根据这个文件，或者你可以在运行时传递过滤器参数：

as per this document, alternatively you can pass filter argument at the runtime:

app/console doctrine:migrations:diff  --em=uac --filter-expression=/whatever/
