[core] Support routing database

I'm creating an web application on hue that talks to the pre-existing database. I have configured database details in settings.py of the application. but its finding the tables in the hue database instead of finding it in database mentioned in settings.py

My requirement is that the web application which I develop, should talk to the pre-existing database, not the hue database which is configured in hue.ini.
I have specified the database details in settings.py of application, which is actually the right way to specify in django+python. but that method is not seem to work in HUE. It tries to see in hue database only. Any workaround to make it work this django feature?
