Is it possible to store the alembic connect string outside of alembic.ini?

Question

I\'m using Alembic with SQL Alchemy. With SQL Alchemy, I tend to follow a pattern where I don\'t store the connect string with the versioned code. Instead I have file secr

So what appears to work is reimplementing engine creation in env.py, which is apparently a place for doing this kind of customizing Instead of using the sqlalchemy connect string in the ini:

engine = engine_from_config(
            config.get_section(config.config_ini_section),
            prefix='sqlalchemy.',
           poolclass=pool.NullPool)

You can replace and specify your own engine configuration:

import store
engine = store.engine

Indeed the docs seems to imply this is ok:

sqlalchemy.url - A URL to connect to the database via SQLAlchemy. This key is in fact only referenced within the env.py file that is specific to the “generic” configuration; a file that can be customized by the developer. A multiple database configuration may respond to multiple keys here, or may reference other sections of the file.
