DatabaseRouter and connections

Hi,

For long time we use a DatabaseRouter and a middleware to choose database to use on the fly. With the time going we have now a lot too much databases configurations in our settings.
So we have made something to dynamically load database configuration in django.db.connections when they are not present but present in a database storying the configurations.

Everything is working well, but before putting it in production, we will be happy to have some feedback about this way of doing things and be sure that it's the good way to load dynamically database configurations.

So is-it correct to add new connections by using this function :

from django.db import connections

def add_db_connection(system_id, name, user, password, host, protocol):

    connections.databases[system_id] = {

        'ENGINE': 'django.db.backends.' + protocol,

        'NAME': name,

        'USER': user,

        'PASSWORD': password,

        'HOST': host,

        'CONN_MAX_AGE': 0

    }

or is they a better way to load new databases configurations ?

Thanks a lot for your answers,

Matthieu
