Create database in Symfony2

Question

I've inherited a Symfony project that uses a MySQL DB. I need to create a second database. I've changed the …/htdocs/projectFolder/app/config/parameters.yml to have a new dbName.

parameters:
    database_driver: pdo_mysql
    database_host: 127.0.0.1
    database_port: 8889
    database_name: inherited_db_name
    database_user: root
    database_password: root
    mailer_transport: smtp
    mailer_host: localhost
    mailer_user: null
    mailer_password: null
    locale: en
    secret: nosecret
    database_path: null

Changed to:

parameters:
    database_driver: pdo_mysql
    database_host: 127.0.0.1 #can't use "localhost"
    database_port: 8889
    database_name: new_db_to_create
    database_user: root
    database_password: root
    mailer_transport: smtp
    mailer_host: localhost
    mailer_user: null
    mailer_password: null
    locale: en
    secret: nosecret
    database_path: null

I have tried all the tricks I can thing of but the command: doctrine:database:create just keeps trying to create “inherited_db_name”

If I drop the “inherited_db_name” DB and then run the command again w/ the new parameters.yml the “inherited_db_name” is recreated. I've searched and grep-ed for the “inherited_db_name” but cannot find out where it's coming from. ANY suggestions would be welcomed.

You should configure your Symfony2 application to manage both databases.

So your parameters.yml file will look like:

parameters:
    database_driver: pdo_mysql
    database_host: 127.0.0.1
    database_port: 8889
    database_name: inherited_db_name
    database_user: root
    database_password: root
    database_driver2: pdo_mysql
    database_host2: 127.0.0.1 #can't use "localhost"
    database_port2: 8889
    database_name2: new_db_to_create
    database_user2: root
    database_password2: root
    mailer_transport: smtp
    mailer_host: localhost
    mailer_user: null
    mailer_password: null
    locale: en
    secret: nosecret
    database_path: null

Now you just need to configure Doctrine properly:

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                driver:   "%database_driver%"
                host:     "%database_host%"
                port:     "%database_port%"
                dbname:   "%database_name%"
                user:     "%database_user%"
                password: "%database_password%"
                charset:  UTF8
            customer:
                driver:   "%database_driver2%"
                host:     "%database_host2%"
                port:     "%database_port2%"
                dbname:   "%database_name2%"
                user:     "%database_user2%"
                password: "%database_password2%"
                charset:  UTF8

    orm:
        default_entity_manager: default
        entity_managers:
            default:
                connection: default
                mappings:
                    AcmeDemoBundle:  ~
                    AcmeStoreBundle: ~
            customer:
                connection: customer
                mappings:
                    AcmeCustomerBundle: ~
