Module: Enumerize::Predicates

Defined in:
lib/enumerize/predicates.rb

Overview

Predicate methods.

Basic usage:

class User
  extend Enumerize
  enumerize :sex, in: %w(male female), predicates: true
end

user = User.new

user.male?   # => false
user.female? # => false

user.sex = 'male'

user.male?   # => true
user.female? # => false

Using prefix:

class User
  extend Enumerize
  enumerize :sex, in: %w(male female), predicates: { prefix: true }
end

user = User.new
user.sex = 'female'
user.sex_female? # => true

Use only and except options to specify what values create predicate methods for.
