Rails - Nov 2005 - Re: <%= text_field("orderitem", '@item') %> (working on it)

ok, so I''m playing with the source now and have gotten this working
(at least on the output side of things).

So my example of:
<% for @order in @orders %>
 ...
 <%= text_field("order[]", ''name'') %>
 ...
 <% for @item in @order.items %>
   ...
   <%= text_field("order[]item[]", ''name'') %>

yeilds something like this:
  <input type="text" name="order[1][name]" ...
  <input type="text" name="order[1]item[1][name]"...
  <input type="text" name="order[2][name]" ...
  <input type="text" name="order[2]item[1][name]"...
  <input type="text" name="order[2]item[2][name]"...

Before I start working on loading this back into model objects upon a
submit, does anyone have any thoughts on this approach?  This
functionality wasn''t left out for any particular reason, was it?

Thanks,
Ben
