Actually you shouldn't need a hidden field. I'm adapting this example
from something slightly different (my Item objects have a description
field, rather than quantity), but here's what I've got:
<% @items.each do |item| %>
<% fields_for "items[]", item do |ff| %>
<p>Description: <%= ff.text_field :description %></p>
<% end %>
<% end %>
and here's what's submitted to the controller in params:
{"items"=>{"345698069"=>{"description"=>"third item"},
"345698067"=>{"description"=>"first item"},
"345698068"=>{"description"=>"second item"}},
"commit"=>"Buy",
etc. }
So now I can iterate through that hash, getting the id number and a
hash of attributes each time.
