symbolic_enum

symbolic_enum is an alternate implementation of Rails enums, which changes the following:

• The getters return symbols instead of strings.
• Option to mark the field as an array. This assumes that the underlying database column is an integer array.
• Option to disable scopes and/or setters.

Add this line to your application's Gemfile:

gem 'symbolic_enum'

And then execute:

$ bundle

Or install it yourself as:

$ gem install symbolic_enum

symbolic_enum is used similar to enum. For example,

class Car < ApplicationRecord
  include SymbolicEnum

  symbolic_enum category: {
    sedan:     0,
    hatchback: 1,
    suv:       2,
    other:     3,
  }
end

# Usage
c = Car.create!
c.sedan!

c.sedan? # true

c.hatchback? # false

c.category = :suv

c.category # :suv
c.save!

Car.suv.pluck(:id).include?(c.id) # true
