Edit the new order page

edit app/views/orders/new.html.erb
<div class="depot_form">
  <fieldset>
    <legend><%= t('.legend') %></legend>
    <%= render 'form' %>
  </fieldset>
</div>

Edit the form used by the new order page

edit app/views/orders/_form.html.erb
<%= form_for(@order) do |f| %>
  <% if @order.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@order.errors.count, "error") %>
      prohibited this order from being saved:</h2>
 
      <ul>
      <% @order.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
 
  <div class="field">
    <%= f.label :name, t('.name') %><br />
    <%= f.text_field :name, size: 40 %>
  </div>
  <div class="field">
    <%= f.label :address, t('.address_html') %><br />
    <%= f.text_area :address, rows: 3, cols: 40 %>
  </div>
  <div class="field">
    <%= f.label :email, t('.email') %><br />
    <%= f.email_field :email, size: 40 %>
  </div>
  <div class="field">
    <%= f.label :pay_type, t('.pay_type') %><br />
    <%= f.select :pay_type, Order::PAYMENT_TYPES,
                  prompt: t('.pay_prompt_html') %>
  </div>
  <div class="actions">
    <%= f.submit t('.submit') %>
  </div>
<% end %>

Define some translations for the new order.

edit config/locales/en.yml
en:
 
  orders:
    new:
      legend:       "Please Enter Your Details"
    form:
      name:         "Name"
      address_html: "Address"
      email:        "E-mail"
      pay_type:     "Pay with"
      pay_prompt_html: "Select a payment method"
      submit:       "Place Order"
edit config/locales/es.yml
es:
 
  orders:
    new:
      legend:       "Por favor, introduzca sus datos"
    form:
      name:         "Nombre"
      address_html: "Direcci&oacute;n"
      email:        "E-mail"
      pay_type:     "Forma de pago"
      pay_prompt_html: "Seleccione un m&eacute;todo de pago"
      submit:       "Realizar Pedido"
