mongoid-app_settings

This is a fairly simple gem to let you work with application configuration that's stored in Mongoid. It's inspired by a similar project called rails-settings, except this stores it in MongoDB using Mongoid.

It's a little more explicit in that it requires you to define a list of settings beforehand.

Usage

Simply create some class and include Mongoid::AppSettings.

class MySettings
  include Mongoid::AppSettings

  setting :enable_my_feature, default: true
  setting :something_else, type: Integer
end

Then you can do things like:

MySettings.enable_my_feature
=> true

MySettings.enable_my_feature = false
MySettings.enable_my_feature
=> false

MySettings.something_else = "42"
MySettings.something_else
=> "42"

You can unset a value (reverting it to the default if given):

MySettings.delete(:enable_my_feature)
MySettings.enable_my_feature
=> true

You can get a list of all values:

MySettings.all
=> {:enable_my_feature => true, :something_else => "42"}

You can get a list of defaults:

MySettings.defaults
=> {:enable_my_feature => true, :something_else => nil}

Settings are cached until manually reloaded. In your ApplicationController, you might want to do something like

class ApplicationController < ActionController::Base
  before_filter :reload_settings

  def reload_settings
    Settings.reload
  end
end

• 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.
