= Redis::Settings

Store application and user settings on Redis. Comes with ActiveRecord support.

== Installation

  gem install redis-settings

Redis::Settings store all data in JSON format. The default parser is yajl-ruby[https://rubygems.org/gems/yajl-ruby], with fallback to json[https://rubygems.org/gems/json]. Make sure you have one of those installed.

== Usage

  require "redis/settings"

  # Reuse an existing Redis connection.
  Redis::Settings.configure do |config|
    config.connection = Redis.new(:host => "localhost", :port => 6379)
  end

  # Create settings namespaced to app
  settings = Redis::Settings.new("app")
  settings.namespace
  #=> "settings/app"

  # Set values
  settings[:items_per_page] = 10
  settings.set(:items_per_page, 10)

  # Get values
  settings[:items_per_page]
  settings.get(:items_per_page)
  settings.get(:items_per_page, 20) #=> return 20 when items_per_page is not defined

  # Remove all settings on this namespace
  settings.clear

  # Retrieve a hash with defined settings
  settings.all

=== ActiveRecord

  class User < ActiveRecord::Base
  end

  user = User.first
  user.settings[:role] = "admin"

<b>NOTE:</b> When record is destroyed, all settings are erased.
