How can I use different databases in every single bundle of Symfony2 with Doctrine2?
FooBundle <- Database "Foo"
BarBundle <- Database "Bar"
This may help How to work with Multiple Entity Managers and Connections.
So you can define multiple Entity Managers related to your databases connections, you can then map your bundle(s) to the right Entity Manager.
The examples on the documentation are well explained.
doctrine: dbal: default_connection: foo_connection connections: foo_connection: # ... # Foo connection parameters # ... bar_connection: # ... # Bar connection parameters # ... orm: default_entity_manager: foo_manager entity_managers: foo_manager: connection: foo_connection mappings: FooBundle: ~ bar_manager: connection: bar_connection mappings: BarBundle: ~
