Question

我第一次使用nested_form gem而且我可能因为资产管道问题而陷入奇怪的问题。这是我的applicatiion.js.coffee文件

这些是我的模特

class MenuItem < ActiveRecord::Base
  belongs_to :menu
  has_many :deal_items
  has_many :item_prices, :dependent => :destroy
  has_many :swap_items
  has_many :required_options
  accepts_nested_attributes_for :item_prices, :reject_if => lambda { |a| a[:price].blank? }, :allow_destroy => true
  accepts_nested_attributes_for :required_options, :reject_if => lambda { |a| a[:question].blank? }, :allow_destroy => true
  belongs_to :section
  validates :item_prices, :presence => true
  has_attached_file :photo, :styles => {:small => '50x50#', :large => '100x100#', :medium=>"80x80#"},
              :default_url => '/assets/images/missing_:style.png'
  attr_accessible :name, :price, :title, :description, :photo, :options, :section_id
end

class RequiredOption < ActiveRecord::Base
  belongs_to :menu_item
  has_many :options
  accepts_nested_attributes_for :options, :reject_if => lambda { |a| a[:choice].blank? }, :allow_destroy => true
  attr_accessible :question, :menu_item_id
end

class ItemPrice < ActiveRecord::Base
  belongs_to :menu_item
  has_many :deal_items
  attr_accessible :size, :price, :menu_item_id
end

我的控制器是

def new
  @section = Section.find(params["section_id"])
  @menu = @section.menu
  @item = @section.menu_items.build
  item_price = @item.item_prices.build
  required_option = @item.required_options.build
  option = required_option.options.build
end

视图看起来像

<%= nested_form_for @item, :url=> section_menu_items_create_path(@section, @item), method: :post, class: "js_menu_form", :multipart => true, :role=>"form" do |f| %>

  <%= f.fields_for :item_prices do |price| %>
    <%= price.select :size, options_for_select(["Regular Size", "Small Size","Large Size","Extra Large Size"]),{},:class=>"form-control" %>
    <%= price.text_field :price, :class=>"form-control ", :placeholder=>"Enter price" %>
  <% end %>
  <p><%= f.link_to_add "Add an item price", :item_prices %></p>

  <%= f.fields_for :required_options do |r_op| %>
    <%= r_op.text_field :question, :class=>"form-control",  :placeholder=>"Enter a question for this option"  %>
    <%= r_op.fields_for :options do |op| %>
    <%= op.text_field :choice, :class=>"form-control",:size=>5, :placeholder=>"Enter choice" %>
    <%= op.link_to_remove "", :class=>"glyphicon glyphicon-trash", :title=> "remove choice" %>
  <% end %>
<% end %>

然而它在我的本地机器上工作正常，但在heroku link_to_add和link_to_remove没有工作没有任何反应当我点击它们没有生成新的表单字段或remvoed我缺少什么。？

nested上没有nested_form链接
