Adding multiple rows of data using a single form

Not sure of an elegant way to do it with form_for but perhaps this will
give you some ideas...

<% form_tag do %>
<% for @owner in @owners %>
<%= text_field("owner[]" , 'firstname') %><br />
<% end %>
<%= submit_tag %>
<% end %>

should work... note the "[]" on owner...

good luck!
