Ruby on Rails：從單個視圖/控制器更新多個模型

Question

使用Ruby 1.8.6 & Rails 1.2。

型號：Job，JobExtraStop：從View

class JobExtraStop < ActiveRecord::Base 
    belongs_to :job 
end 

class Job < ActiveRecord::Base 
    belongs_to :lead, :foreign_key => :id 
    has_one :quote, :foreign_key => :id 
    has_many :credit_card 
    has_many :job_extra_stops 
end 

代碼：

主視圖

<%= render_partial 'jobs/job_address_stop_fields', "stop" => stop, "index"=> index %> 

部分被稱爲：

<span class="jasf" id="lead_form_adrr_fields"> 

<% fields_for "job_extra_stop[#{index}]", stop do |extra_stop_form| %> 
<tr> 
     <td><%= extra_stop_form.text_field :st_num, :size => 2%></td> 
      <td><%= extra_stop_form.text_field :st_name, :size => 15%></td> 
      <td><%= extra_stop_form.text_field :apt_num, :size => 2%></td> 
      <td><%= extra_stop_form.text_field :city, :size => 9%></td> 
      <td><%= extra_stop_form.text_field :zip, :size => 5%></td> 
      <td><%= extra_stop_form.select(:state,([[ "Select State", "" ]] + State::NAMES)) %> 

      </td> 
      <td><%= extra_stop_form.text_field :floor, :size => 2%></td> 
      <td>&nbsp;&nbsp;<%= extra_stop_form.text_field :elevator, :size => 1%></td> 
      <td>&nbsp;&nbsp;<%= extra_stop_form.text_field :action_type, :size => 5%></td> 
      <td>&nbsp;&nbsp;<%= extra_stop_form.select(:location_type, ([["pick-up"],["drop-off"],["extra_stop"]])) %></td> 
      <td>&nbsp;&nbsp;<%= extra_stop_form.text_field :note, :size => 10%></td> 
      <td>^/v</td> 
      <td>&nbsp;&nbsp;<%= link_to_function "Remove", "$(this).up('.jasf').remove()" %></td> 
</tr> 
<% end %> 
</span> 

錯誤：

Undefined Local Variable or method index

不知道我在做什麼錯。
