    The collection_select helper is used for when you want the options within the select element to come from a collection of ActiveRecord models. For your requirements you should use the select helper in combination with options_for_select:

    <%= select(:country, :country_id,
  options_for_select([['US', 1], ['UK', 2], ['AUS', 3], ['PAK', 4]])) %>
