A simple key value store for ActiveRecord based applications.

Best used to store global app settings.

Add it to your Gemfile

gem 'persistent_settings'

Install

bundle install

Use the generator to create a Config class, or whatever you want to call it, that will include all the Persistent Settings functionality.

rails g persistent_settings:create config

Run migrations

rake db:migrate

Assuming that your Persistent Settings class is named Config, it will automatically create new keys as you assign a value to them.

Config.a_key = 'value'

Reload your app:

Config.a_key # => 'value'

It accepts all kinds of objects as the value

Sometimes, settings are not loaded automatically at startup. If that's the case add an initializer to your Rails app.

#
# config/initializers/settings.rb
#

Settings.load_from_persistance

Starting from version 1.4 this gem is compatible with Rails 4.0 or better, if you are looking for a version compatible with Rails 3.x then use version 1.3 of this gem.
