Question

在Rails 5上工作我正在尝试在每个动态标签中呈现嵌套表单（相同模型），但是现在在所有选项卡中都呈现相同的格式，如何在不同的选项卡中呈现不同的字段集

views / material_masters / new.html.erb

var dbvar;
...
.then(() => {
   //var dbvar; <-- delete this line
   dbvar=1; // <- can access outer dbvar
   console.log(dbvar); //Log HERE
...

视图/material_masters/_material_location_fields.html.erb

<div class="col-md-12">
   <div class="panel panel-default">
     <div class="panel-body">
      <div class="tabbable-line">
        <ul class="nav nav-tabs ">
          <% @part_locations.each.with_index do |l, i| %>
          <li <%= 'class="active"' if i == 0 %>>
            <a href="#<%= l.location_name %>" data-toggle="tab"> <%= l.location_name %> </a>
          </li>
          <% end %>
          <li><button type="button" class="fa fa-plus btn btn-primary btn-xs" data-toggle="modal" data-target="#myModal"></button> </li>
        </ul>
        <div class="tab-content">
          <% @part_locations.each.with_index do |l, i| %>
          <div class="tab-pane <%= 'active' if  i == 0 %>" id="<%= l.location_name %>">
            <%= f.fields_for :material_locations do |builder| %>
            <%= render 'material_location_fields', :f => builder  %>
            <% end %>
            <%= link_to_add_association "Add", f, :material_locations, class: "btn btn-primary btn-xs"  %>
          </div>
          <% end %>
        </div>
      </div>

    </div>
  </div>
</div>

模型/material_master.rb

<fieldset>
  <div class= "nested-fields">
    <div class="col-sm-3">
      <%= f.label :material_location, "Material Location" %>
      <%= f.text_field :mat_location,class:"form-control",required: true %>
    </div>
    <div class="col-sm-3">
      <%= f.label :opening_stock  %>
      <%= f.text_field :opening_stock ,class:"form-control",onKeyPress:"return NumbersOnly(this, event,true)",required: true  %>
    </div>
    <div class="col-sm-3">
      <%= f.label :reorder_qty %>
      <%= f.text_field :reorder_qty, class:"form-control",onKeyPress:"return NumbersOnly(this, event,true)",required:true  %>
    </div>
  </div>
</fieldset>

听见，我想在bangalore标签中添加位置，我正在添加孟买的位置，在delhi标签中，我想添加一个实质性的位置，但是下一个标签中将出现相同的表格

Answer 1

您的代码上显然有一行空格：

<a href="#<%= l  .location_name %>" data-toggle="tab"> <%= l.location_name %> </a>

您可以注意到l .location_name可以删除空格吗？
