Ruby on rails: nested attribute form doesn't show up

I am working on Rails 3.1.1.rc3 and I have 2 classes as shown below.

class Customer < ActiveRecord::Base
  has_many :orders, :dependent => :destroy
  accepts_nested_attributes_for :orders
end

class Order < ActiveRecord::Base
  belongs_to :customer
end

In my form: 

<%= form_for(@customer) do |f| %>
  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name,:class=>'textbox' %>
  </div>

  <%= f.fields_for :orders do |order_form| %>   
    <div class="field">
       <%= order_form.label :number %><br />
       <%= order_form.text_field :number, :class=>'textbox' %>
   </div>  
  <%end%>

<%end%>

When it renders, the first part of the form (for customer) shows up, but the second part (for order) doesn't. Any pointers are appreciated. Thanks.

add 

<%= f.fields_for :orders do |order_form| %>

instead of

<% f.fields_for :orders do |order_form| %>

Edit: have a look at how fields_for is defined (there are examples there)

Two things. First fields_for basically iterates over customer.orders so if there are no orders you'll get no output. If you just want some blank fields for users to input order details you'd typically stick

@customer.orders.build

In your controller. Secondly, fields_for is very similar to form_for, you need to use <%= for it too
