“从购物车中删除产品”按钮不起作用

Question

我在 Spree 应用中从购物车按钮中删除产品时遇到问题。 我有一个购物车，有部分 _line_item.html.erb：

<%= order_form.fields_for :line_items, line_item do |item_form| %>
  <tr class="first odd">
    <td class="image"><a class="product-image" title="Sample Product" href="#/women-s-crepe-printed-black/">
      <% if variant.images.length == 0 %>
        <%= link_to small_image(variant.product), variant.product %>
      <% else %>
        <%= link_to image_tag(variant.images.first.attachment.url(:small)), variant.product %>
      <% end %>
    </td>
    <td><h2 class="product-name">
      <%= link_to line_item.name, product_path(variant.product) %>
       </h2>
    </td>
    <td class="a-center"><a title="Edit item parameters" class="edit-bnt" href="#configure/id/15945/"></a></td>
    <td class="a-right"><span class="cart-price"> <span class="price">
      <%= line_item.single_money.to_html %></span> </span>
    </td>
    <td class="a-center movewishlist">
      <%= item_form.number_field :quantity, min: 0, class: "form-control line_item_quantity", size: 5 %>
    </td>
    <td class="a-right movewishlist"><span class="cart-price"> <span class="price">
      <%= line_item.display_amount.to_html unless line_item.quantity.nil? %></span> </span>
    </td>
    <td class="a-center last cart-item-delete ">
      <%= link_to content_tag(:span, '', class: 'glyphicon glyphicon-minus-sign'), '#', class: 'delete', id: "delete_#{dom_id(line_item)}" %>
    </td>
  </tr>

<% end %>

最后一个表格单元格是指从购物车按钮中删除产品，但是当点击该购物车时没有任何反应

<%= link_to content_tag(:span, '', class: 'glyphicon glyphicon-minus-sign'), '#', class: 'delete', id: "delete_#{dom_id(line_item)}" %>

Answer 1

它可能会起作用：

<%= link_to content_tag(:span, '', class: 'glyphicon glyphicon-minus-sign'), line_item_path(line_item), method: :delete, class: 'delete', id: "delete_#{dom_id(line_item)}" %>

Answer 2

考虑添加

<%= javascript_include_tag "application" %>

到 layouts/spree_application.html.erb

另外，请确保在您的资产管道中添加... assets/javascripts/spree/frontend.js 看起来像这样

    //= require jquery
    //= require jquery_ujs 
    //= require spree
    //= require spree/frontend/checkout
    //= require spree/frontend/product
    //= require spree/frontend/cart
    //= require spree/frontend/locale_selector

这应该可以正常工作：
