No :)
So, yeah, if you want just a single submit button then you'll want a
single form and you should use fields_for with the :index option...
<% form_for ....etc. do %> <%# ....you can just have a
form_tag here if you want %>
<% @users.each do |user| %> <%# total aside: this is more Ruby-
ish syntax %>
<%= other things %>
<% fields_for user, :index => user.id do |f| %>
<%= f.radio_button :approval ..etc. %>
<% end %>
<% end %>
<%= submit_tag %>
<% end %>
You'll find that all the radio buttons will be indexed, so you'll
receive params[:user][id_of_user][:approval] in your controller, so
you can easily set the right values for the right user all in one
action.
