Question

I have an app that talks to two different databases. For one of my entities, School, I get the following error:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'pressbox.schools' doesn't exist

That makes sense because there is no pressbox.schools. It’s fnt.schools. It’s trying to talk to the wrong database.

How do I tell my entity which mapping I want it to use? I would of course rather refer to the mappings than to the database names themselves, which can be different depending on the environment.

Answer 1

First, declare your connections in a config file (config.yml would be fine):

doctrine:
  dbal:
    default_connection: pressbox # change it as you wish
    connections:
      pressbox:
        driver:   %database_driver%
        host:     %database_host%
        port:     %database_port%
        dbname:   pressbox
        user:     pressbox_usr
        password: pressbox_pwd
        charset:  UTF8
      fnt:
        driver:   %database_driver%
        host:     %database_host%
        port:     %database_port%
        dbname:   fnt
        user:     fnt_usr
        password: fnt_pwd
        charset:  UTF8

Then declare the entity managers:

doctrine:
  orm:
    default_entity_manager: pressbox
    entity_managers:
      pressbox:
        connection: web
      fnt:
        connection: fnt

Now, in a controller, you can tell Doctrine which entity manager to use by passing its name to getEntityManager():

$fntEm = $this->getDoctrine()->getEntityManager('fnt');

Assuming the entity manager for the fnt table is called that same name.
