This approach is ugly (because of putting the mapper within the local

import model
model.setup(dsn)

This there any better pattern for implementing this?

you don't need to pass DSN as a parameter.  The "engine" argument to
declarative_base() is optional, and the docs have been revised in
recent months to reflect this.

However the engine is required in order to perform autoloading.
