rails. How to save user settings to a file?

Question

Ruby on Rails

settingslogic - plugin that reads user settings from yml file. How, after setting new values ​​in the app, these settings are saved?

Answer 1

Form and overwrite yml with a new file.
It doesn't read user settings, it provides a convenient way to implement "static" application settings. (something like this).
PS It's not a plugin, it's a gem :)

Answer 2

For example gem https://github.com/ledermann/rails-settings

Ruby gem to handle settings for ActiveRecord instances by storing them as serialized Hash in a separate database table. Namespaces and defaults included.
