Generate boolean method like ActiveRecord::Enum

[james-em]

class Conversation < ActiveRecord::Base
  enum :status, [ :active, :archived ]
end

conversation.new(status: :active)
conversation.active? # => true

Syntax is shorter than

user.sex?(:male)    # => true
user.sex?(:Male)    # => true
user.sex?('Male')   # => true

Special note: In case of method overlap, ActiveRecord::Enum let's you define suffix or prefix.

enum :status, [ :active, :archived ], prefix: true

conversation.status_active? # => true

Valid values are for prefix/suffix

true, false(default), string
