Rails - Jan 2011 - Help with looping through groups of radio buttons

So my goal is to loop through and list several groups of shipping
options for various products. First I loop through the number of items
which need to be shipped alone, then I loop through the shipping
rates. What I want is each group to be able to have 1 selection and
pass along the params for use in the controller.

I need the ability to iterate or count the ss_ship_info so that each
name/value will be different params. I have tried both
''ss_ship_info[@counter]'' and
''ss_ship_info''[@counter] (this one has
really unexpected results, if I have 3 items. The first two act like a
single group but the third seems to be an individual group.)

Does anyone know a solution for my problem or at the very least could
point me in the direction of a guide relating to the subject?


##CODE##################

<% @sscount.times do %>  #First Loop


   <% for rate in @ups_ss_rates[@counter] %> # Second Loop
      <label>
         <%= radio_button_tag(''ss_ship_info[]''[@counter],
rate[0]) %>
         <%= rate[0] %> - <span
class="money"><b><%sub_number_to_currency((rate[1]))
%></b></span>
      </label>
    <% end %>

   <% @counter += 1 %>

<% end %>

The formtastic gem might be able to help you.
https://github.com/justinfrench/formtastic

It makes writing forms a lot easier and has helpers for writing groups
of buttons and stuff.  Here''s an example from the readme on github...
 f.input :authors, :as => :check_boxes, :collection => User.find(:all,
:order => "last_name ASC")
  f.input :authors, :as => :check_boxes, :collection =>
current_user.company.users.active
  f.input :authors, :as => :check_boxes, :collection => [@justin, @kate]
  f.input :authors, :as => :check_boxes, :collection =>
["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :author,  :as => :select,      :collection =>
Author.find(:all)
  f.input :author,  :as => :select,      :collection => { @justin.name
=> @justin.id, @kate.name => @kate.id }
  f.input :author,  :as => :select,      :collection =>
["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :author,  :as => :radio,       :collection => User.find(:all)
  f.input :author,  :as => :radio,       :collection => [@justin, @kate]
  f.input :author,  :as => :radio,       :collection => { @justin.name
=> @justin.id, @kate.name => @kate.id }
  f.input :author,  :as => :radio,       :collection =>
["Justin",
"Kate", "Amelia", "Gus", "Meg"]
  f.input :admin,   :as => :radio,       :collection => ["Yes!",
"No"]
