Ruby on rails rails中的嵌套表单参数和简单表单

我试图让一个嵌套表单在一个表单中创建用户与其地址之间的关联

我看到的问题是，每当验证失败时，内部地址字段表单都不会重新填充，也不会显示验证错误

以下是表格：

<%= simple_form_for(@user, :url => register_and_checkout_path, :html => {:class => "form-horizontal clearfix"}) do |f| %>
<p>New Member &amp; Guest</p>
<small>Mandatory fields marked*</small>
     <%= f.error_notification %>
     <%= f.input :is_checkout, :as => :hidden, :input_html => { :value => true } %>
      <%= f.input :first_name, :input_html => {:class => "input-xlarge"} %>
      <%= f.input :last_name, :input_html => {:class => "input-xlarge"} %>
      <%= f.input :email, :input_html => {:class => "input-xlarge", :placeholder => "you@youremail.com"} %>

     <%= simple_fields_for (:address) do |a| %>
        <%= a.input :phone1, :label => "Contact number", :input_html => {:class => "input-xlarge"}  %>
        <p class="uppercase">Your Address</p>
        <%= a.input :address_1, :label => "Street Address", :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :address_2, :label => false, :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :address_3, :label => false, :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :suburb, :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :state, :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :postcode, :label => "Postcode/zipcode", :input_html => {:class => "input-xlarge"}  %>
        <%= a.input :country, :priority => [ "Australia", "New Zealand", "Unites States", "United Kingdom" ] %>

     <% end %>
        <p>Become a valued member</p>
        <%= f.input :password, :input_html => {:class => "input-xlarge"}  %>
        <%= content_tag(:button, :class => 'btn btn-large btn-success floatright') do %> <%= content_tag :i, '', :class => 'icon-white icon-shopping-cart' %> Register and Checkout <% end %>
     <% end %>
</div>

最后是相关模型：

class Member::User < ActiveRecord::Base
  authenticates_with_sorcery!
  # attr_accessible :title, :body

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :address, :address_attributes, :first_name, :last_name, :order_attributes, :pending_order, :is_checkout

  attr_accessor :is_checkout


  # Orders and Order History
  has_many :orders, :class_name => "Checkout::Order"
  has_one  :pending_order,
           :class_name => "Checkout::Order",
           :conditions => ['status = ?', 'P']


  has_many :addresses, :class_name => "Member::Address"
  has_one  :primary_billing_address,
           :class_name => "Member::Address",
           :conditions => ['is_primary_billing = ?',true]
  has_one  :primary_shipping_address,
           :class_name => "Member::Address",
           :conditions => ['is_primary_shipping = ?',true]
  has_one :address,
          :class_name => "Member::Address",
          :conditions => ['is_primary_billing = ?', true]

  accepts_nested_attributes_for  :address
  accepts_nested_attributes_for  :pending_order

  validates_presence_of :email, :password, :first_name, :last_name
  validates_confirmation_of :password
  validates_uniqueness_of :email

end

class成员：：用户“签出：：订单”
有一个：待定订单，
：class_name=>“Checkout:：Order”，
：条件=>['status=？'，'P']
有多个：地址，：class\u name=>“成员：：地址”
有一个：主账单地址，
：class_name=>“成员：：地址”，
：conditions=>['is_primary_billing=？'，true]
有一个：主装运地址，
：class_name=>“成员：：地址”，
：条件=>['is_primary_shipping=？'，true]
有一个：地址，
：class_name=>“成员：：地址”，
：conditions=>['is_primary_billing=？'，true]
接受地址的\u嵌套\u属性\u
接受：挂起的\u订单的\u嵌套\u属性\u
验证是否存在：电子邮件、：密码、：名字、：姓氏
验证密码的确认
验证电子邮件的唯一性
结束

对于任何想找到这个问题答案的人来说，我发现了，这是一个非常简单的错误，花了很多时间试图找出答案，结果是表单中的这一行

<%= f.simple_fields_for :address do |a| %>

请注意，容器表单生成器现在引用了的简单字段

<%= f.simple_fields_for :address do |a| %>
