Setting API other than using Meta?

[evandavey]

My ORM api instance needs to be dynamically declared (to pass in the API url and login via oauth2).

I've used this technique but is there a better way?

api = make_api(api_url)
api.type_registry.register(Design)
Design._options.api = api

Same issue. I can't declare an api outside of application context, because I am using flask globals.
Is there any solution of how I can set up api not in Meta class?
