• Rails: fields_for makes it easy to create View form fields for nested objects. For example, from the Rails API Docs:

<code>
  <% form_for :person, @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 :permission, @person.permission do |permission_fields| %>
      Admin?  : <%= permission_fields.check_box :admin %>
    <% end %>
  <% end %>
</code>
