No fields_for doesn't do any iteration. It's used for setting up a
scope for one or more form fields for a different object than the one
which scopes an outer form_for
>From the doc:
<% form_for @person, :url => { :action => "update" } do |person_form| %>
First name: <%= person_form.text_field :first_name %>
Last name : <%= person_form.text_field :last_name %>
<% fields_for :person do |permission_fields| %>
Admin?: <%= permission_fields.check_box :admin %>
<% end %>
<% end %>
So just like form_for doesn't do any iteration, neither does fields_for.
Since you haven't told us any more about what you want to do, I don't
know how to help any further.
