Rails - Jul 2006 - radio_button groups

For my first rails app, I''m building a web page that will list some 
restaurants and then have the user rate them from from 1 to 5 using 5 
radio buttons.  The view code looks like:

<h3>Ratings:</h3>
<form action="save_ratings" method="post">
  <table>
    <tr>
      <th>Restaurant</th>
      <% for rating_option in [1,2,3,4,5] -%>
        <th><%=h rating_option.to_s -%></th>
      <% end -%>
    </tr>
    <% for user_rating in @ratings -%>
      <tr>
        <td><%=h user_rating.restaurant.name -%>: </td>
        <% for rating_option in [1,2,3,4,5] -%>
          <td><%= radio_button(:user_rating, :rating, rating_option) 
-%></td>
        <% end -%>
      </tr>
    <% end -%>
  </table>
  <input type="submit" value="Save">
</form>

Where @ratings contains an array of objects from find(:all), and I want 
to assign the value of the radio button to user_rating.rating (an int 
field in the table).

This code links all the radio buttons for all rows in one group.  How 
can I assign a group of radio buttons to a specific row?  Also, where is 
the documentation on the options hash for radio_button?

Thanks,
Aaron
