Rails: Bootstrap dropdown menu not working

Question

I am quite new to Rails and have been following the tutorial by Michael Hartl. Everything has been going along really well until I got to the drop down menu, which was wasn't working, then was working and now isn't working :( I've read several posts and fixes and I suspect my tinkering has gotten to the point where quite simply, I've done something to stop it working. I will say that I initially had the bootstrap-sass 2.x in my gem file, then changed it to 3.x, but went back to 2.x because I didn't realise that going to 3.x would result in issues due to class name changes. So, perhaps the time this was working was when I had bootstrap-sass 3.x installed, not sure. From what I can tell though everything is set up the way it needs to be. I am developing under Windows 8.1 and I had to fix an issue with execjs and in specific the runtimes.rb file. So, here are my details:

Gemfile:

source 'https://rubygems.org'
ruby '1.9.3'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.2'
gem 'bootstrap-sass', '2.3.2.0'
gem 'sprockets', '2.11.0'
gem 'bcrypt-ruby', '3.1.2'

# Use sqlite3 as the database for Active Record
gem 'mysql2', '0.3.15'

# Use SCSS for stylesheets
gem 'sass-rails', '4.0.1'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '1.3.0'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '4.0.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails'

# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '1.2'

application.js

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require_tree .

_header.html.erb (where the drop down is)

<header class="navbar navbar-fixed-top navbar-inverse">
  <div class="navbar-inner">
    <div class="container">
      <%= link_to "Catered Fit", root_path, id: "logo" %>
<!--      <%= link_to image_tag("logo.jpg", width: "25%"), root_path %>    -->
      <nav>
        <div class="nav pull-right">
<!--          <li><%= link_to "Home", root_path %></li>
          <li><%= link_to "Help", help_path %></li>   -->
          <% if !signed_in? %>
            <div class="navbar-form">
            <%= form_for(:session, url: sessions_path) do |f| %>
              <div class="span2 input-xlarge">
                <% f.label :email %>
                <%= f.text_field :email, placeholder: "Email" %>
              </div>
              <div class="span2 input-small">
                <% f.label :password %>
                <%= f.password_field :password, placeholder: "Password" %>
              </div>
              <div class="span2">
                <%= f.submit "Sign in", class: "btn btn-primary" %>
              </div>
            <% end %>
          <% else %>  
            <li><%= link_to "Users", '#' %></li>
            <li id="fat-menu" class="dropdown">
              <a href="#" class="dropdown-toggle" data-toggle="dropdown">
                Account <b class="caret"></b>
              </a>
              <ul class="dropdown-menu">
                <li><%= link_to "Profile", current_user %></li>
                <li><%= link_to "Settings", edit_user_path(current_user) %></li>
                <li class="divider"></li>
                <li>
                  <%= link_to "Sign out", signout_path, method: "delete" %>
                </li>
              </ul>
              <li><%= link_to "Sign out", signout_path, method: "delete" %></li>
            </li>
          <% end %>
        </div>
      </nav>
    </div>
  </div>
</header>

I don't see any errors in the console window and apart from the drop down everything else is working fine.

The following is the source code from the webpage:

Would really appreciate some help on this to get past this issue.

Thanks in advance, and please let me know if I can provide anymore information.

I changed the order of directives in app/assets/javascripts/application.js to:
//= require jquery //= require jquery_ujs //= require bootstrap //= require_tree .

Worked like a charm :)

Odd it hasn't been fixed yet. But this solution worked for me as well. I had to add //= require turbolinks between bootstrap and require_tree as well.

What I was able to determine was the issue was 2 rouge js files that I had placed in the assets/javascript directory. Namely, bootstrap.js and bootstrap.min.js. Once I removed these files the dropdown was working again.

May be the issue is rails loading all bootstrap assets twice.

you can try to call it via javascript adding :

<script>
   $('.dropdown-toggle').dropdown()
</script>

at the botton of your _header file.

hope helps!

I tried every solution here: github.com/twbs/bootstrap-sass/issues/714 ++ at least 10 others. none of them worked. This worked for me.

The problem is bootstrap's javascript. Sometimes is loaded two times.

This works to me:

application.js:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require bootstrap

application.scss: Don't use //= require in scss files

@import "*";
@import "bootstrap";
@import "font-awesome";

Then:

rake assets:clean
rake assets:precompile

OR

Put bootstrap.js in assets/javascripts folder and put //= require_tree . line

Using a later version of rails (5.2.3) I found that the instructions given in the book didn't work. The console warned me that jQuery needed to be installed, and by going to https://github.com/rails/jquery-rails I was able to find the instructions to get it up-and-running.

Add to the Gemfile:

gem 'jquery-rails'

Add to application.js

//= require jquery
//= require bootstrap

So that the whole Gemfile is

//= require rails-ujs
//= require activestorage
//= require jquery
//= require bootstrap
//= require turbolinks
//= require_tree .

In modern version of the book (rails 6+) this is what i've done to make it work:

In app/javascript/packs/application.js change the order of

require("jquery");
import "bootstrap";

to be before turbolinks - so final implementation of application.js looks like:

require("jquery");
import "bootstrap";
require("@rails/ujs").start();
require("turbolinks").start();
require("@rails/activestorage").start();
require("channels");

Book shows to add jquery & bootstrap at the end after turbolinks - what in my opinion causes the problem. Thanks!
