Rails 4 - which order to put jQuery and bootstrap?

Question

I'm trying to figure out how to load assets in my application.js.

I have these required files (among others) in my application.js.

//= require bootstrap-sprockets
//= require jquery
//= require jquery-ui
//= require jquery_ujs

My gem file has:

gem 'jquery-rails'
gem 'jquery-ui-rails'

When bootstrap-sprockets is before jQuery, then my bootstrap dropdown menu (below) works fine.

<div class="row" style="margin-top:30px">
    <div class="col-md-3 col-md-offset-8">
        <% if policy(@project).show? %>    

            <div class="btn-group">
              <button type="button" style="color: black" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                STATUS: <%= text_for_state(@project.current_state) %> <span class="caret"></span>
              </button>
              <ul class="dropdown-menu">
                 <% if policy(@project).request_preapproval? %>    
                    <%= link_to "REQUEST APPROVAL", request_preapproval_project_path(@project), method: :put, :style=>"padding-left:20px; padding-right: 10px" %>
                <% end %>
                <li role="separator" class="divider"></li>
                <% if policy(@project).publish? %>    
                    <%= link_to "PUBLISH", publish_project_path(@project),  method: :put, :style=>"padding-left:20px; padding-right: 10px" %>
                <% end %>
                <li role="separator" class="divider"></li>

                <!-- <a href="#" class='btn btn-primary'>REQUEST MORE INFORMATION</a> -->
                <% if policy(@project).update? %>

                    <%= link_to "EDIT PROJECT", edit_project_path(@project), :style=>"padding-left:20px; padding-right: 10px" %>
                <% end %>

                 <li role="separator" class="divider"></li>
                <% if policy(@project).edit? %>    
                    <%= link_to "REMOVE", edit_project_path(@project), :style=>"padding-left:20px; padding-right: 10px" %>
                <% end %>
              </ul>
            </div>


        <% end %>
    </div>    
</div

However, in that case, my tab show function on the following setup doesnt work. I can't click on the tabs. If I move jQuery above bootstrap-sprockets, it does work, but then the drop down menu, which otherwise works, stops working.

<div class="row">
                <div class="col-md-10 col-md-offset-1">
                    <div class="dp-tab-1">
                        <ul class="dp-tab-list row" id="myTab">
                            <li class="col-md-3 col-xs-6 active" >
                                <a href="#tab-guag-content-first">
                                    <span>MOTIVATION</span>
                                </a>
                            </li>
                            <li class="col-md-3 col-xs-6">
                                <a href="#tab-guag-content-second">
                                    <span>OBJECTIVES</span>
                                </a>
                            </li>
                            <li class="col-md-3 col-xs-6">
                                <a href="#tab-guag-content-third">
                                    <span>VISION</span>
                                </a>
                            </li>

                        </ul>

                        <div class="dp-tab-content tab-content">
                            <div class="tab-pane row fade in active" id="tab-guag-content-first">

                                <div class="col-md-12">

When I try to render the page in the case when bootstrap is loaded before jQuery, I get this error in the chrome inspector console tab:

main.self-9711b4c….js?body=1:56 Uncaught TypeError: dp(...).tab is not a function(anonymous function) @ main.self-9711b4c….js?body=1:56dispatch @ jquery.self-660adc5….js?body=1:5227elemData.handle @ jquery.self-660adc5….js?body=1:4879

How can I solve this so that I can have both the drop down and the tabs working?

My entire application.js is:

//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require bootstrap-sprockets
//= require html.sortable
//= require disqus_rails
//= require moment
//= require bootstrap-datetimepicker

I have tried all of the suggestions in this post: none of them work for me: https://github.com/twbs/bootstrap-sass/issues/714

Answer 1

Works perfectly.

//= require jquery
//= require jquery-ui 
//= require jquery_ujs
//= require bootstrap-sprockets

You have defined bootstrap.js before the jquery. but in every application you should defined jquery at the top, so it would be load first.

Answer 2

This worked for me: https://stackoverflow.com/a/22977412/2860931 It doesnt feel like an actual solution - but rather a work around. I'll take that as good enough for now. I've tried at least 30 different solutions posted in various places on SO.
