Hi, I''m using: select(object, method, choices, options = {}, html_options = {}) I''ve read the API where there''s this example: select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank => true }) should give this code: <select name="post[person_id]"> <option></option>
