A couple of ideas to throw in the mix. I'd like to see a Meta
option. Like:
Meta:
using = 'db2'
So you have a default for your model.
Additionally what about just using the generative syntax for the
using. It doesn't seem that a lot is to be gained by using the
context manager. For instance:
User.objects.using('db2').all()
Also when thinking about third-party plugable applications you have to
consider how you're going to handle that. If you have a third party
app and you want it to all be directed to a particular database, how
does that get handled in your scenario above?
Just a couple of things to consider.
