skip radio buttons when posting the form (rails)
===

I have a rails from inside that I have some radio buttons which I dont want to post in my Edit action

    <form accept-charset="UTF-8" action="/feedbacks/3" id="edit_feedback_3" method="post">
     <input id="1_1" name="1" type="radio" value="1" />Yes
     <input id="1_1" name="1" type="radio" value="1" />No
     <input id="feedback_answers" name="feedback[answers]" size="30" type="text" />
     <input name="commit" type="submit" value="Submit" />
    </form>

and these radio buttons are not bind to a model attributes, How can I POST only the 'feedback_answers' to server. 

All this is because I'm facing this issue with radio buttons (https://rails.lighthouseapp.com/projects/8994/tickets/3030-rails-does-not-handle-typeerror-from-rack-on-malformed-query-strings)

I'm using ruby 1.9.2 and rails 3.2.6, thanks in advance
