cymbalize

Use symbols in ActiveRecord columns. This gem implements a subset of nofxx's symbolize gem.

Installation

Include the gem in your Gemfile:

gem 'cymbalize', '~> 0.1.0'

Features

Please note that :scopes, :methods, and :allow_blank don't do anything unless :in is an array with at least one symbol.

Symbolize a column with symbolize

class User < ActiveRecord::Base
  symbolize :gender
end

u = User.new(:gender => :robot)
u.gender # :robot

Add a list of valid values with :in

class User < ActiveRecord::Base
  symbolize :gender, :in => [:decepticon, :autobot]
end

u = User.new(:gender => :autobot)
u.valid? # true
u.gender = :robot
u.valid? # false

Add boolean methods with :methods

class User < ActiveRecord::Base
  symbolize :gender, :in => [:asterix, :obelix], :methods => true
end

u = User.new(:gender => :asterix)
u.asterix? # true
u.obelix? # false

Add ActiveRecord scopes with :scopes

class User < ActiveRecord::Base
  symbolize :gender, :in => [:zerg, :protoss, :terran], :scopes => true
end

u = User.create(:gender => :zerg)
User.zerg.include?(u) # true
User.protoss.include?(u) # false

Allow blank values with :allow_blank

class User < ActiveRecord::Base
  symbolize :gender, :in => [:mod, :rocker], :allow_blank => true
end

u = User.new(:gender => nil)
u.valid? # true
u.gender # nil

u.gender = ''
u.valid? # true
u.gender # nil
