To generate a working sele <%= collection_select(:person, :city_id, City.all, :id, :name) %> ``` +As with other helpers, if you were to use the collection_select helper on a form builder scoped to the @person object, the syntax would be: + +```erb +<%= f.collection_select(:city_id, City.all, :id, :name) %> +``` + To recap, `options_from_collection_for_select` is to `collection_select` what `options_for_select` is to `select`.
