I am using Alembic for migrations implementation in a Flask project. There is a alembic.ini file where the database configs must be specified:
sqlalchemy.url = driver://user:password@host/dbname
Is there a way to specify the parameters from the environment variables? I've tried to load them in this way $(env_var) but with no success. Thanks!
I've solved the problem by setting sqlalchemy.url in env.py as @dirn suggested.
config.set_main_option('sqlalchemy.url', <db_uri>) did the trick, where <db_uri> can be loaded from environment or config file.
