那些遇到过的问题

表单提交按钮仅在重新加载后有效

Gar*_*che 20 ruby-on-rails ruby-on-rails-4

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.我没有看到刷新会有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？)我看不到刷新前后的形式html有任何区别.有什么想法可能会发生什么？

我不确定甚至开始寻找什么代码,但是这里有.

index.html.erb

...
<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 %>

  <% if @bom.new_record? %>
    <%= render("form_in_table", form_objects: [@li, @bom] , button_text: "Add") %>

如果这对解密代码/意图很有用,我会收集line_items,parts和boms; line_item有很多boms,line_item有许多部分通过boms.除了部件/订单项关系之外,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.每讨论一个表内表,<form>不能放在里面<table>或<tbody>或<tr>.移动后<form>包装表并将控件放在相应<td>的表单中.

我仍然不明白为什么刷新页面使表单工作,但...

  • 一开始以为是 turbolink 问题，但后来发现我在表格中使用了表单标签。 (2认同)

如果它是Rails 4,那可能是因为Turbolinks.试试看

data-no-turbolink="true" inside your body tag
Run Code Online (Sandbox Code Playgroud)

这可能有用,它发生在我身上一次.

  • 这不是解决方案，而是补丁，您正在禁用Turbolinks：/尽管这是一个有效的决定，但这不是解决问题的方法。Garret和Jerome的答案更好。 (2认同)

此类错误通常是由无效HTML生成的错误.各种错误来源可能是:

  • 失踪<或>
  • HTML标记未关闭
  • 孤立的HTML结束标记(没有开放的标记); 在复杂的形式中,我有额外</div>的谎言......
  • 嵌套在表单中的表单table或tr标签(td允许内部)

表单助手需要正确嵌套,否则这些怪癖会咬你...

use*_*745 5

对于 Rails 5，请尝试使用data: { turbolinks: false }指向包含表单的页面的任何内部链接。

例如<%= link_to "Get in Touch", 'contact', data: { turbolinks: false } %>
