表单提交按钮仅在重新加载后有效
我有一个构建表的索引页面，我试图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Rails提供它。
我的表在index方法中显示正常，并且有一个表单作为表中的最后一行，可用于添加新行。 新表格工作正常。 每行都有一个编辑链接，可以路由到控制器的编辑方法。 控制器设置要编辑的对象，并使用要编辑的行中的表单呈现索引。 我的问题是这个表单不会提交，但如果我刷新页面就会提交。
页面将在刷新后提交的事实非常令人困惑。 我没有看到刷新会如何做什么不同然后点击链接（它应该仍然通过相同的路由，相同的变量对吗？）我看不清楚刷新前后的formshtml有什么区别。 有什么想法可能会发生什么？
我不确定甚至开始查看的代码是什么，但是这里有。
index.html.erb
... ... _form_in_table.html.erb
_bom_in_table.html.erb
boms_controller.rb
... 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 ...
如果这对解密代码/意图很有用，我有line_items，parts和boms的集合; line_item有很多boms，line_item有许多部分通过boms。 除了零件/订单项关系外，boms还有一个数量。 Bom是物料清单的缩写。 @li是被操纵的line_item。 我遇到问题的表单是查看/添加/编辑属于订单项的boms（数量和部件）的集合。

我相信这是一个HTML问题，而不是Rails问题。 根据此讨论表格中的表格 ，
不能放在
或
或
。 移动
以包装表并将控件放在相应的
表单后工作。
我仍然不明白为什么刷新页面使表单工作，但…
如果它是Rails 4，那可能是因为Turbolinks。 试试吧
data-no-turbolink="true" inside your body tag
这可能有用，它发生在我身上一次。
此类错误最常由无效HTML生成。 各种错误来源可能是：
- 缺少
<或> - HTML标记未关闭
- 孤立的HTML结束标记（没有开放的标记）; 在复杂的forms我有额外的
s谎言... - 嵌套在
table或tr标签内的表单（允许在td内）
表单助手需要正确嵌套，否则这些怪癖会咬你...
对于rails 5，请尝试在包含该表单的页面的任何链接中使用data: { turbolinks: false } 。
例如<%= link_to "Get in Touch", 'contact', data: { turbolinks: false } %>
