best_in_place gem不會更新關聯的記錄

Question

我試圖從購物車內的訂單更新屬性。爲此，我希望使用best_in_place gem（https://github.com/bernat/best_in_place）
進行就地編輯，無論如何，一旦它被實現，它就不會在提交時更新記錄。

這是我的看法：

= form_for @order, :url => update_cart_path, :html => {:id => 'update-cart'} do |order_form| 
%div#line_items_list 
    - @order.line_items.each do |line_item| 
    %section#line-item.columns.twelve 
     %div.line_picture.columns.three.alpha 
     %div#line_picture 
      = image_tag(line_item.variant.images.first.attachment.url(:product)) unless line_item.variant.images.length == 0 
     %div#line_description.nine.columns.omega 
     %span#line_title.nine.columns 
      %span.columns.alpha= full_product_name(line_item.variant) 
      %span#line_price.offset-by-five.columns.omega= money line_item.price 
     %div#optionsvariant 
      - if line_item.variant.option_values.any? 
      - line_item.variant.sorted_values.each do |ov| 
       %div#line_item_options 
       %span= ov.option_type.presentation 
       - if ov.swatch? 
        %span.imagelabel= image_tag("#{ov.swatch.url(:circle)}") 
       - else 
        %span.textlabel.not_selected= ov.presentation 
      %div#orderquantity 
      Quantity 
      = best_in_place [@order, line_item], :quantity, :type => :input 
      - if line_item.subscription_line? 
      %p#subline Auto ship: first pair ships today and every 1 month. 

這是我的控制器更新aciton：

def update 
@order = current_order 
    respond_to do |format| 
    if @order.update_attributes(params[:order]) 
     format.html do 
     @order.line_items = @order.line_items.select {|li| li.quantity > 0 } 
     fire_event('spree.order.contents_changed') 
     respond_with(@order) { |f| f.html { redirect_to cart_path } } 
     end 

     format.json { respond_with_bip(@order)} 
    else 
     format.html {respond_with(@order)} 
     format.json {respond_with_bip(@order)} 

    end 
    end 
end 

它怎麼會是正確的方式來做到這一點，所以它更新我的LINE_ITEM的數量在購物車？

Answer 1

卸下

=的form_for @order，：URL => update_cart_path，：HTML => {：ID => '更新購物車'}做| order_form |

從表單頂部解決了問題。
