Symfony same webservice working on Databases

Here is the issue:

I have some methods in action in a Symfony project that are defined in WSDL. I need a configuration where my ws can work on one of two data bases according to environment. I tried defining different environments and even different applications.But they all insist to use the DB from the database开发者_运维问答s.yml under the config on the level of apps.

I really appreciate any help

In order to select the database connections dynamically you can use the same technique demonstrated in this slide
