无法获取动态内容的样式

Question

我遇到了奇怪的行为：bootstrap 在我的页面上有些效果，但没有为表单设置样式。

我可以看到它加载了，而且都是因为按钮、flexbox、网格系统。但是我无法将其设置为样式表。在这里，我在同一页面上显示与静态表单具有相同代码的动态表单：

静态表单的样式正确，而动态表单只是规范化，没有应用任何样式。我认为它与链轮有关，但很难弄清楚。

编辑:

<div class="col-md-6">
  <%= form_for(@form) do |f| %>
    <%= render partial: 'shared/req_errors', locals: {scope: "req_statuses.fields"} %>

    <div class="form-group">
      <%= f.label t('.dest') %><br>
      <%= f.select :dest, ReqStatus.dests.collect {|c| [t(".#{c}"), c] } %>
    </div>

    <div class="form-group">
      <%= f.label t('.note') %><br>
      <%= f.text_area :note, cols: 40, placeholder: t('.note-placeholder') %>
    </div>

    <div class="form-group">
      <%= f.label t('.copies') %><br>
      <%= f.select :copies, (1..Request::MAX_NUMBER_OF_COPIES) %>
    </div>

    <div class="actions">
      <%= f.submit t('.submit'), class: "btn btn-primary" %>
    </div>

  <% end %>

我想您忘记为动态表单控件应用 CSS。尝试向表单中的所有控件添加 form-control class 会有所帮助。
