How do i specify and validate an enum in rails?

Question

I currently have a model Attend that will have a status column, and this status column will only have a few values for it. STATUS_OPTIONS = {:yes, :no, :maybe}

Answer 1

You could use a string column for the status and then the :inclusion option for validates to make sure you only get what you're expecting:

class Attend < ActiveRecord::Base
    validates :size, :inclusion => { :in => %w{yes no maybe} }
    #...
end
