在轨道表内的嵌套窗体（茧宝石）

问题描述：

我忙于一个发票应用程序，我试图从茧宝石内嵌<tbody></tbody>嵌套窗体。嵌套表格可以很好地工作，但它不会显示在<tbody></tbody>中，而是在桌面上方的某个随机位置。我认为这是因为你不能在桌子内部有<div class=nested-fields></div>，但我不知道如何以不同的方式做到这一点。在轨道表内的嵌套窗体（茧宝石）

我有这个在我的发票/ _form.html.erb：

<%= form_for @invoice do |f| %> 
<% if @invoice.errors.any? %> 
    <div id="error_explanation"> 
     <h2><%= pluralize(@invoice.errors.count, "error") %> prohibited this invoice from being saved:</h2> 

     <ul> 
     <% @invoice.errors.full_messages.each do |message| %> 
     <li><%= message %></li> 
     <% end %> 
     </ul> 
    </div> 
    <% end %> 
     <div class="row"> 
      <div class="col-sm-12"> 
      <table class="table table-striped"> 
       <thead> 
       <tr> 
       <th class="hidden-480"> Hoeveelheid </th> 
       <th class="hidden-480"> Beschrijving </th> 
       <th class="hidden-480"> Bedrag </th> 
       <th class="hidden-480"> Totaal </th> 
       <th class="hidden-480"> Btw(%) </th> 
       </tr> 
       </thead> 
       <tbody> 
       <%= f.fields_for :products do |product| %> 
       <%= render 'product_fields', f: product %> 
       <%= link_to_add_association 'Item toevoegen', f, :products, class: 'btn btn-primary btn-success' %> 
       <% end %> 
       </tbody> 
      </table> 
      </div> 
     </div> 
    <% end %>

发票/ _product_fields.html.erb

<div class="nested-fields"> 
    <tr> 
     <td> <%= f.text_field :quantity %> </td> 
     <td> <%= f.text_area :description %> </td> 
     <td> <%= f.number_field :unitprice %> </td> 
     <td> €200 </td> 
     <td> <%= f.select(:btw, [[' 21%', 21, title: '21%'],[' 6%', 6, title: '6%'], [' 0%', 0, title: '0%']]) %> </td>

任何想法是怎么回事？帮助将非常感谢！

什么是f的对象？你能证明f来自哪里以及模型中的关联吗？ –

新增所有内容，感谢您的帮助！ – luissimo

您可以参考控制cocoon gem的插入行为部分以获取有关插入嵌套字段的更多参考。

例如，

$(document).ready(function() { 
    $("#owner a.add_fields"). 
     data("association-insertion-method", 'append'). 
     data("association-insertion-traversal", 'closest'). 
     data("association-insertion-node", '#parent_table'); 
});

可以简单地使用内置的茧创业板link_to_add_association提供的方法，

参考： https://github.com/nathanvda/cocoon#link_to_add_association

<%= link_to_add_association 'Item toevoegen', f, :products,:"data-association-insertion-node" => "tbody#{id of tbody encapsulating your fields_for}",:"data-association-insertion-method" => "append", class: 'btn btn-primary btn-success' %>

PS这是我的第一个答案stackoverflow，所以我提前道歉，如果我不够清楚。
