Hi all, I can''t figure out why my radio_buttons won''t reflect the values stored in my database. I read through some of the previous posts -- is it true that they don''t work with integers? This is the code I''m using: <% for question in @survey.questions %> <%= debug question %> <%= radio_button ( "question", :question_id, question.option_one.id) %> <%= question.option_one %> <%= radio_button ( "question", :question_id, question.option_two.id) %> <%= question.option_two %> <% end %> The "debug question" statement prints out the correct values. I have to think that I''m using the wrong parameters in the radio_button call, but nothing I try is working. I guess I could use the radio_button_tag builder but radio_button seems better. Any help would be greatly appreciated! Thanks, Eugene -- Posted via http://www.ruby-forum.com/.

Did you try putting "question_id" rather than :question_id ? Did you try putting question.option_one.id.to_s ? The helper is maybe looking for a string, and you are giving it an integer. Hopefully my lame attempt to help might inspire someone who knows what they are talking about to give you a definitive solution :) Robert Jones -- Posted via http://www.ruby-forum.com/.

Hmm, I''m starting to think it has something to do with having to use an instance variable ... sound right to you? I''m experimenting right now, I''ll post any progress. -- Posted via http://www.ruby-forum.com/.
To all who follow in my footsteps, I''ve decided to go with the radio_button_tag (http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#M000501) which was infinitely easier for me to configure. Good luck, and if anyone does get this working with the radio_button helper, I''d be interested to know how. -Eugene -- Posted via http://www.ruby-forum.com/.
