Rails Enum with prefix/suffix

[enum]:http://api.rubyonrails.org/classes/ActiveRecord/Enum.html

Today I learned that Rails 5 released new options for [enum][] definition: _prefix and _suffix.

class Conversation < ActiveRecord::Base
  enum status:          [:active, :archived], _suffix: true
  enum comments_status: [:active, :inactive], _prefix: :comments
end

conversation.active_status!
conversation.archived_status? # => false

conversation.comments_inactive!
conversation.comments_active? # => false
