nested_form 中点击添加后怎么为 text_field 添加 id


view


 erb


 <%=f.fields_for :specifications do |spe|%>


<div class="col-sm-12">
    <label class="control-label col-sm-2 col-sm-offset-1">库存数:</label>
    <% sizes.each do |size| %>
      <div class="col-sm-1">
        <%= text_field_tag "inventories#{ spe.object.id }[]", "",class: 'form-control' %>
      </div>
    <% end %>
  </div>


<% end %>



<div class="form-group">
  <%= f.link_to_add '+添加一个规格', :specifications, class: 'col-sm-12' %>
</div>

我想实现的是,在点击添加的时候在text_field_tag上添加一个ID或者类似用来辨识的标识,然后我在后台就可以直接用那个辨识符进行更新操作。

现在能获取到的参数,如下是两个以存在的specification,另外新建的三个合并在一起了。


 shell


 "inventories19"=>["", "", "", "", "", "", ""], "inventories20"=>["", "", "", "", "", "", ""], "inventories"=>["", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", "", ""]

希望有人能帮我解惑一下。
