I'm trying to use a yaml config file as a very simple flat file db for a small rails app. The app has a single user, so I just need a way to store a username and password. The only thing is that I'd like to be able to edit the username and password while still inside the app and not require an app restart (so I can't load the YAML file inside an initializer...).
Any ideas on how I could accomplish this? I'm not married to the idea of using YAML, so if you have a better suggestion I'm all ears!
You really are better off using a database for this sort of thing, because it's how Rails is designed to work. The Rails default database is SQLite 3, which is a high-performance, reliable single file database.
Don't fight the defaults—use the right tool for the job.
