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}") %\>
