我正在尝试使用Rails 4制作应用程序。
我正在为嵌套字段使用cocoon gem，以便嵌套子集。
我也在使用bootstrap。
我很挣扎，因为如果出现错误，我的页面会显示：“请查看以下问题：”但是没有任何内容突出显示，我找不到错误的位置。
如何设置嵌套字段以在父页面中显示错误 - 甚至在嵌套的部分表单中也可以。
我在我的主要形式中使用了许多部分，
当我尝试编辑配置文件（主）对象时，我可以在控制台中看到更新似乎已提交，但是表单再次使用上面的错误消息呈现（但没有任何标识错误是什么）

对于cocoon gem，地址表格如下：
<div class="nested-fields">
<div class="container-fluid">
<div class="form-inputs">
<div class="row">
<div class="col-xs-3">
<%= f.input :unit %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :street_number %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :street %>
</div>
</div>
<div class="row">
<div class="col-xs-3">
<%= f.input :building %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :city %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :region %>
</div>
</div>
<div class="row">
<div class="col-xs-3">
<%= f.input :zip %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<!--f.country_select(:country, {selected: @profile.country_name}, {class: "form-control"}) -->
<%= f.country_select :country, priority: [ "Australia", "New Zealand", "United Kingdom" ] %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :time_zone %>
</div>
</div>
<div class="row">
<div class="col-xs-3">
<%= f.input :main_address %>
</div>
<div class="col-xs-3 col-xs-offset-1">
<%= f.input :project_offsite %>
</div>
</div>
<div class="row">
<div class="col-md-6">
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<%= link_to_remove_association 'Remove this address', f %>
</div>
</div>
</div>
</div>
<div class = "debug" > <%= yield %> <%= debug(params) if Rails.env.development? %></div>
然后在我的个人资料表格中添加：
<%= link_to_add_association 'Add an address', f, :addresses, partial: 'addresses/address_fields' %>
这令人沮丧，因为我无法找到任何错误可能导致更新停止处理的指示。

看起来您的嵌套表单不确定它们与哪些相关联。您应该在输入字段中嵌套按钮。
<div class="row-fluid">
<div class="col-md-12">
<h3>Your Title</h3>
<div id="Your-form">
<%= f.simple_fields_for :your_tables do |table| %>
<%= render 'table_fields', f: table %>
<% end %>
<div class="links"></div>
<%= link_to_add_association 'Add', f, :your_tables, class: 'btn btn-secondary add-button' %>
</div>
</div>
</div>
并且有一部分看起来像这样。
<div class="form-inline clearfix">
<div class="row">
<div class="nested-fields">
<%= f.input :table, placeholder: "Enter a Value", label: false, input_html: { class: "form-input form-control", style: 'width:80%;'} %>
<%= link_to_remove_association "Remove", f, class: "form-control btn btn-secondary", style: 'height:20%; display:inline; float:right;' %>
</div>
</div>
</div>

如果没有任何示例，很难说你是如何使用这些嵌套表格的，但我们假设。
使用关联中的默认验证器时，应始终突出显示有错误的元素，如果您使用自定义验证器，请确保将错误添加到正确的关联中，否则表单中不会显示任何内容。
