Question

我的应用程序中有invoice和invoice_items模型。我已经使用cocoon gem来嵌套models.i我正在使用rails 4.2。它在我创建新发票时工作正常，但当我点击我的编辑按钮时，我得到“模板缺失错误”，虽然我在我的应用程序中有_invoice_item_fields.html.erb文件。

这是我的_form.html.erb文件

<div class=" form">
  <%= form_for(@invoice,:html=>{:class=>"cmxform form-horizontal tasi-form",:novalidate=>"novalidat"}) 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="form-group ">
          <%= f.label :billing_address ,:class=>"control-label col-lg-2" %>
        <div class="col-lg-6">
          <%= f.text_area :billing_address,:class=>"form-control"  %>
        </div>  
    </div>
      <div class="form-group ">
          <%= f.label :shipping_address ,:class=>"control-label col-lg-2" %>
        <div class="col-lg-6">
          <%= f.text_area :shipping_address,:class=>"form-control"  %>
        </div>  
    </div>
      <div class="form-group ">
          <%= f.label :company_id ,:class=>"control-label col-lg-2" %>
        <div class="col-lg-6">
          <%= f.number_field :company_id,:class=>"form-control"  %>
        </div>  
    </div>
      <div class="form-group ">
          <%= f.label :invoice_date ,:class=>"control-label col-lg-2" %>
        <div class="col-lg-6">
          <%= f.date_select :invoice_date,:class=>"form-control"  %>
        </div>  
    </div>
      <div class="form-group ">
          <%= f.label :status ,:class=>"control-label col-lg-2" %>
        <div class="col-lg-6">
          <%= f.number_field :status,:class=>"form-control"  %>
        </div>  
    </div>

    <div class="row">
  <div class="col-lg-12">
    <section class="panel">
      <header class="panel-heading">
          Invoice Items
          <span class="pull-right">
          <%= link_to_add_association 'Add Item', f, :invoice_items,:class=>"btn btn-default"%>
        </span>  
      </header> 
      <div class="panel-body">
        <div class="adv-table">
          <%= f.fields_for :invoice_items do |item| %>
            <%= render '_invoice_item_fields', :f => item %>
          <% end %>
        </div>    
      </div>  
     </section> 
  </div>
</div>   


     <div class="form-group">
        <div class="col-lg-offset-2 col-lg-10">
          <%= f.submit "Save",:class=>"btn btn-danger"%>
        </div>  
    </div>
  <% end %>
</div>

这是我的_invoice_item_fields.html.erb文件

Answer 1

此...

<%= render '_invoice_item_fields', :f => item %>

必须是

<%= render 'invoice_item_fields', :f => item %>

您不要在Rails _调用中使用前导render来呈现部分内容。下划线仅用于磁盘上的文件名。

缺少部分发票/ __ invoice_item_fields
