I agree with @tamersalama. Here's a simple way to do it using strings in the DB with a custom Enum class. Note that this also supports human readable names for use in dropdown menus.

SQL:

Table name: snacks
 id                         :integer
 ice_cream                  :string

Rails:

class Snack < ActiveRecord::Base
  FLAVORS = Enum.new [
      [:vanilla, "Vanilla"],
      [:chocolate, "Chocolate"],
      [:rocky_road, "Rocky Road"]
      ])
  ]
end

HTML:

<%= simple_form_for @snack do |f| %>
<%= f.collection_select :ice_cream, Snack::FLAVORS, :value, :label %>
<% end %>
