Would this perhaps be easier to do after the Apps-Refactor (#3591)
lands? I'm not real familiar with that ticket, but if we're trying to
set a connection on a app level - that seems like the easiest way to
do it via settings. Something like:
INSTALLED_APPS = (
app('django.contrib.auth', connection='my_user_db'),
...
)
Not sure how that would work for over-riding the default
get_connection method though. We'd probably still be referring to a
callable by 'dotted.path.to.a.function' syntax. And it would apply to
all models in an app, not just some.
Just a thought.
