问题描述

我有一个具有自己的数据库的Symfony2项目,现在我想连接到另一个数据库(另一个项目),所以我可以修改一些表。



我创建config_dev.yml中的新连接

  doctrine:
dbal:
default_connection:default
连接:
默认值:
驱动程序:pdo_mysql
主机:localhost
dbname:database1
用户:root
密码:
buv:
驱动程序:pdo_mysql
主机:localhost
dbname:database2
用户:root
密码:

我尝试使用以下命令导入模式:


$ php app / console doctrine :mapping:import --em = buv MyBundle yml



[Doctrine\DBAL\Sc hema\SchemaException]
索引''不存在于表'old_table'


但是数据库2中的某些表没有PK!而且全部进口都不行。但是我只想导入两个表,所以我试过:


$ php app / console doctrine:mapping:import --em = buv --filter =tablenameMyBundle yml


但是我收到相同的错误,似乎--filter不工作。



控制台命令中的文档doctrine:mapping:import只表示将实体名称放在filter选项中。但是我还没有一个实体。

解决方案

如果我正确地找到你想要导入现有的数据库? / p>

我所做的是:

  php app / console doctrine:mapping :转换xml ./src/App/MyBundle/Resources/config/doctrine/metadata/orm --from-database --force 

然后做一个选择性转换为注释:

  php app / console doctrine:mapping:import AppMyBundle annotation --filter =users_table

如果您想要yml,请将注释更改为yml。



警告:当您导入注释或yml时,它将删除您当前的实体文件。


I have a Symfony2 project with its own database, and now I want to connect to another database (another project) so I can modify some tables.

I created the new connection in config_dev.yml

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   pdo_mysql
                host:     localhost
                dbname:   database1
                user:     root
                password: 
            buv:
                driver:   pdo_mysql
                host:     localhost
                dbname:   database2
                user:     root
                password:

I tried to import the schema with the following command:

$ php app/console doctrine:mapping:import --em=buv MyBundle yml

[Doctrine\DBAL\Schema\SchemaException] Index '' does not exist on table 'old_table'

But some of the tables in database2 have no PKs! And the full import dosn't work. But I only want to import two tables, so I tried:

$ php app/console doctrine:mapping:import --em=buv --filter="tablename" MyBundle yml

But I'm getting the same error, seems that --filter isn't working.

The documentation in the console command doctrine:mapping:import only says to put the entity name in the filter option. But I don't have an entity yet.

解决方案

If I get you correctly, you want to import your existing database?

What I do is:

php app/console doctrine:mapping:convert xml ./src/App/MyBundle/Resources/config/doctrine/metadata/orm --from-database --force

Then do a selective convert to annotation:

php app/console doctrine:mapping:import AppMyBundle annotation --filter="users_table"

If you wanted to yml, change annotation to yml.

warning: when you import to annotation or yml, it will delete your current entity file.
