Mongoid Enum Mapper

Inspired by ActiveRecord::Enum, the library supports a lightweight solution to map enum key value

Installation

Add this line to your application's Gemfile:

gem 'mongoid_enum_mapper'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mongoid_enum_mapper

Usage

# Allow Mongoid to have ActiveRecord like Enum type of Mapping

#=> OrderDelivery.rb Model
include Mongoid::EnumMapper
define_enum :status, { pending: 0, shipping: 1, shipped: 2 }

# Examples
od = OrderDelivery.new
od.status             #=> Default :pending
od.status = :shipping #=> :shipping
od.status             #=> :shipping
od[:status]           #=> 1

od.status = :invalid  #=> :invalid
od.status             #=> :shipping

od.update(status: :pending)
od.status             #=> :pending

OrderDelivery::STATUS #=> { pending: 0, shipping: 1, shipped: 2 }
OrderDelivery.update_all(OrderDelivery::STATUS[:shipping])
