我有一个建立表的索引页，我正在尝试允许用户编辑表中的行。我试图以最基本的方式做到这一点--没有javascript、ajax等，除非是Rails提供的。

我的表在index方法中显示得很好，并且有一个表单作为表中的最后一行，可用于添加新行。新的表单运行良好。每一行都有一个路由到控制器的edit方法的edit链接。控制器设置要编辑的对象，并呈现索引，这一次是在要编辑的行中使用一个表单。我的问题是这个表单不会提交，但是如果我刷新页面，它就会提交。

页面将在刷新后提交这一事实非常令人困惑。我看不出刷新与单击链接有什么不同(它应该仍然通过相同的路由，使用相同的变量，对吗？)在刷新之前和之后，我看不到表单html有什么不同。有谁知道可能会发生什么吗？

我甚至不确定该从什么代码开始查找，但这里有；

index.html.erb

代码语言：javascript
复制
...
<tbody>
  <% @boms.each do |line| %>
   <% if line == @bom %>
     <%= render("form_in_table", form_objects: @bom , button_text: "Update") %>
    <% else %>
      <%= render("bom_in_table", line: line) %>
    <% end %>
  <% end %>
  <% if @bom.new_record? %>
    <%= render("form_in_table", form_objects: [@li, @bom] , button_text: "Add") %>
  <% end %>
</tbody>
...

_form_in_table.html.erb

代码语言：javascript
复制
<%= form_for(form_objects, html: {class: "form-in-table"}) do |f| %>
  <tr>
    <td><%= f.text_field :quantity %></td>
    <td colspan="2">
      <%= f.select(:part_id,
                   options_from_collection_for_select(@parts, :id, :pricebook_name),
                   prompt: "Select a Part",) %></td>
    <td></td>
    <td></td>
    <td></td>
    <td><%= f.submit(button_text, class: "btn btn-primary btn-mini") %></td>
  </tr>
<% end %>

_bom_in_table.html.erb

代码语言：javascript
复制
<tr>
  <td><%= line.quantity%></td>
  <td><%= line.part_number %></td>
  <td><%= line.part_description %></td>
  <td><%= number_to_currency(line.part_cost) %></td>
  <td><%= line.part_unit %></td>
  <td><%= number_to_currency(line.extension) %></td>
  <td><%= link_to('Edit', edit_bom_path(line)) %></td>
</tr>

boms_controller.rb

代码语言：javascript
复制
...
def edit
  @bom = Bom.find(params[:id])
  @li = @bom.line_item
  @boms = @li.boms.sorted_by_part_number
  @parts = Part.sorted_by_number
  render 'index'
end
...

如果这对破译代码/意图很有用，我有line_items、parts和boms的集合；line_item有很多boms，line_item通过boms有很多parts。除部件/行项目关系外，boms表还具有数量。Bom是Bom表的缩写。@li是被操纵的line_item。我遇到问题的表单是用于查看/添加/编辑属于行项目的物料清单(数量和部件)的集合。

我相信这是一个HTML问题，而不是Rails问题。根据本讨论Form inside a table，<form>不能放在<table>、<tbody>或<tr>中。在移动<form>以包装表格并将控件放入相应的<td>中之后，表单就可以工作了。

我仍然不明白为什么刷新页面会让表单工作，但是...

如果是Rails4，可能是因为Turbolinks。试着把

代码语言：javascript
复制
data-no-turbolink="true" inside your body tag

这可能行得通，它曾经在我身上发生过。

尝试将data-no-turbolink="true“放入调用表页的链接中。

代码语言：javascript
复制
 <a href="/vender" data-no-turbolink="true">

这对我来说很管用。
