Fiona - Rails 3 configuration data engine.

Fiona lets you store unstructured configuration data in your SQL database. Examples include application settings and template data. Any JSON compatible datastructures and values are permitted (integer, float, string, hash, array, true, false, null, etc).

Requirements

  • Rails 3.x (tested with Rails 3.1)

Gem Installation

With bundler

Add the following to your Gemfile and run the 'bundle' command:

gem "fiona"

Configuration

After you install the gem, you need to run Fiona's generator:

rails generate fiona

Usage

Create an instance of Template:

t = Template.new(:key => 'some_template')
t.some_var = 'some sweet value'
t.save!

In the above example, 't' can have as many variables associated with it as you want. Their values can be any JSON supported datatype including hashes, array, strings, etc.

Subclassing

The Template class can be subclassed since it uses Rails STI. The included SettingsTemplate feature is an example of this.

SettingsTemplate

Fiona comes with a template class named SettingsTemplate and an associated Rails initializer. Together they simplify the management of application settings and provide your application with globally accessible settings through the 'S' constant.

TODO

  • Create a generator for creating subclasses of Template.
  • Improve caching.

Contributing to Fiona

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
  • Fork the project
  • Start a feature/bugfix branch
  • Commit and push until you are happy with your contribution
  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
