Editing multiples rows in a single table

I have a table that contains user options, so the table looks like
id
username
option_name
option_value

How do I create a single page that allows me to edit all the options?
Would it be something like

<% form_for :options, :url => { :action => "update_options" } do |
form> %>
<tr>
  <td><%= form.label :option_name %></td>
  <td><%= form.text_field :option_value %></td>
</tr>
<% end %>
<%= submit_tag "save", :class => "save" %>

If so, how do I send both the id and username?

Thanks,
