 # Configure the database connection

-# By default the application wrote its SQLite database into the
-# `/tmp` directory. On local machines this works, but on hosted
-# platforms like Hugging Face Spaces the `/tmp` directory is not
-# persistent across sessions. That means any data stored in
-# `/tmp/codingo.db` would be lost once the process restarts, and
-# newly created user accounts would appear to disappear immediately.
-#
-# To fix this we store the database file inside the project under
-# `backend/instance/codingo.db`. The `backend/instance` directory
-# already exists (it is created by `os.makedirs` below) and is
-# persisted across requests, so user registrations and other data
-# remain available. SQLAlchemy requires three slashes for a relative
-# SQLite URI (e.g. `sqlite:///relative/path.db`). Here we use four
-# leading slashes because the path is relative to the project
-# directory when using `sqlite:///backend/instance/codingo.db`.
