我正在尝试在Rails 5项目中使用recurring_select来选择事件的重复日期。除了jquery模态弹出窗口外，其他一切似乎都可以正常工作。我怀疑这与我在项目中配置资产管道的方式有关，因为当我在全新的单一模型脚手架项目中测试recurring_select时，它可以工作。但这在我的“真实”项目中不起作用。我针对“实际”项目的资产管道方法的差异包括： -将CDN链接用于Jquery（如bootstrap 4启动指南中所示），不包括application.js中jquery的require语句 -在application.js和application.css中不包含require_tree，而是指定：
<%= stylesheet_link_tag 'application', media: 'all' %>
<%= javascript_include_tag 'application' %>
在我的application.html.erb文件中。
这个新手非常感谢任何指导。谢谢。

select_recurring方法以“新遭遇”形式使用，如下所示：
<h1>New Encounter</h1>
<%= bootstrap_form_with(model: @encounter, local: true) do |form| %>
<% if @encounter.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@encounter.errors.count, "error") %> prohibited this encounter from being saved:</h2>
<ul>
<% @encounter.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= form.collection_select(:participant_id, Participant.all, :id, :name_with_initial, {prompt: 'Select Participant'}, {required: true}) %>
</div>
<div class="field">
<%= form.radio_button :encounter_type, 'work', required: true %>
<%= form.radio_button :encounter_type, 'group', required: true %>
<%= form.radio_button :encounter_type, 'other', required: true %>
</div>
</br>
<div class="field">
<%= form.collection_check_boxes :service_ids, Service.all, :id, :name, checked: @encounter.service_ids %>
</div>
<div class="field">
<%= form.date_field(:encounter_date, :value => form.object.encounter_date || Date.current) %>
<%= form.select_recurring :recurring, nil, allow_blank: true %>
</div>
<div class="field">
<%= form.text_field(:duration_hours, :value => form.object.duration_hours || 3.0) %>
</div>
<div class="field">
<%= form.fields_for :work_goal_assessment do |assessment| %>

我想知道将CDN脚本引用放在标签的底部，但这是引导程序将其放在文档中的地方。仅出于笑容，我将其移至application.html.erb中的“ yield”语句之上，但此操作无济于事。我也将其放在本节的顶部，这也没有帮助。仍然出现相同的错误。我也将CDN源换成了https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js，但这没有帮助。谢谢您的关注！

arieljuod在评论中提供了答案。我需要确保<％javascript_include_tag'application'％>出现在加载jquery的脚本之后。
