Prefered

Prefered allows you to add preferences / settings to any model that extends ActiveRecord::Base in a Rails 3 project

Installation

Gem

You can let bundler to install Prefered by adding this line to your application’s Gemfile:

gem 'prefered'

And then execute:

bundle install

Or install it yourself as:

gem install prefered

DB

Next you will need to run the generator which will create the db migration for you:

rails g prefered:preferences_migration

Then migrate your db:

rake db:migrate

Usage

Now your all installed you can add preferences to your active record model, for instance for a User model:

class User < ActiveRecord::Base
  has_preferences do
    preference :colour, :default => 'green'
    group :email
      preference :html, :default => false
    end
  end
end

This would add the following to your user model:

user.preferences.colour #=> 'green'
user.preferences.email.html #=> false

To change preferences you simply use a setter for each preference:

user.preferences.colour= 'yellow'
user.preferences.email.html= false

And to persist them just save the user model:

user.save

Thanks

Thanks to anyone who gives this a try, peace & love, Rob :)
