using an array object in a form helper

rubyonrails-talk

I have an array of the attributes of an object that I would like to use to generate a form. For example, I'd like to say

       <% fields_for :questions do |f|%>          <% for c in @attributes %>              <%= f.text_field [c] %>

how can I use an element of the array in place of [c] ? I normally would put ":attributename"

Try:

<%= f.text_field eval(":#{c}") %>
