Bitfield value object for ActiveModel. No hidden definitions. No callbacks. Magicless.

Build Status

Sponsored by Evil Martians

Installation

Add this line to your application's Gemfile:

gem 'bitfield_attribute'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bitfield_attribute

Usage

Add integer column to your model:

class AddNotificationSettingsToUsers < ActiveRecord::Migration
  def change
    add_column :users, :notification_settings, :integer, default: 0
  end
end

Define bitfield class:

class User::NotificationSettings
  include BitfieldAttribute::Base

  define_bits :weekly_digest, :announces, :events
end

Define accessor in the model:

class User < ActiveRecord::Base
  def notification_settings
    @notification_settings ||= User::NotificationSettings.new(self, :notification_settings)
  end

  def notification_settings=(value)
    notification_settings.attributes = value
  end
end

Use it:

user = User.new(notification_settings: {weekly_digest: true})
user.notification_settings.announces = true

user.notification_settings.weekly_digest?   # => true
user.notification_settings.to_a             # => [:weekly_digest, :announces]
user.notification_settings.attributes       # => { weekly_digest: true, announces: true, events: false }
user[:notification_settings]                # => 3

ActiveModel I18n & forms

Modify your bitfield class:

class User::NotificationSettings
  include BitfieldAttribute::Base
  extend  ActiveModel::Naming
  extend  ActiveModel::Translation

  define_bits :weekly_digest, :announces, :events
end

Add this to your locale file:

en:
  activemodel:
    attributes:
      "user/notification_settings":
        weekly_digest: 'Weekly top sellers digest'
        announces: 'Announces'
        events: 'Invitations'

Use forms:

= form_for @user do |form|
  = form.fields_for :notification_settings, form.object.notification_settings do |f|
    = f.check_box :weekly_digest
    = f.label :weekly_digest

  ...

  = form.submit 'Save'
