I'm trying to set up my first Rails 7 app and have installed Bootstrap 5 properly (you can see by the CSS) and gotten rid of all the error messages, but the javascript functions (i.e. dropdown menus, offcanvas, etc.) aren't working.

I have tested it with this code:

<script>
  $( document ).ready(function() {
    console.log( "document ready!" );
    $( "#TEST" ).click(function() {
      console.log( "clicked!" );
    });
  });
</script>

And both console.log statments produce the correct result, leading me to believe js and jquery are working properly and it is something with bootstrap.

Here's my gemfile:

source ''
git_source(:github) { |repo| "{repo}.git" }

ruby '3.1.0'

# RAILS GENERATED STUFF

  gem 'spring'
end

group :test do
  gem 'capybara', '>= 3.26'
  gem 'selenium-webdriver'
  gem 'webdrivers'
end

Here's my application.js, which lives in 'javascript/controllers/application.js but somehow also inassets/builds/application.js. I'm not using webpack, rather rollup installed with $ ./bin/rails javascript:install:rollup`:

// Configure your import map in config/importmap.rb. Read more:

import 'offcanvas';

//= require jquery3
//= require jquery_ujs
//= require jquery-ui
//= require popper
//= require bootstrap
//= require activestorage
//= require font_awesome5
//= require tinymce



window.jQuery = $;
window.$ = $;

Can anyone see where I'm going wrong?

Can anyone see where I'm going wrong?

• javascript
• ruby-on-rails
• bootstrap-5
• ruby-on-rails-7

• Out of curiosity, did you manage to get the application generated from the command line using the css=bootstrap option? It's failing for me – EastsideDev Commented Feb 25, 2022 at 11:13

I had the same problem.

I got things working by adding the bundle script from Bootstrap in the between the body tags of the application.html.erb file:

<body>
    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg+OMhuP+IlRH9sENBO0LRn5q+8nbTov4+1p" crossorigin="anonymous"></script>
    <%= yield %>
</body>

Check to make sure you have the right version of Bootstrap with the example Bootstrap code. Version 4 markup wont work with Version 5 Bootstrap.

Specifically this attribute changed from:

data: { toggle: "dropdown"}

to

data: { "bs-toggle" => "dropdown"}

If you're "Search" form is stacked and not 100% width, it's a sign you may have the wrong version

It should look like this:

This is the version 5.3 NavBar: https://getbootstrap.com/docs/5.3/components/navbar/

I had some major problems with this. To fix, go into app/javascript/application.js and change this

import "@hotwired/turbo-rails"

to this

import { Turbo } from "@hotwired/turbo-rails"
Turbo.session.drive = false

Also, always use bin/dev to start the rails server in development, rather than the rails server command.

Between the body tag on application.html.erb:

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>

After this, the JS expression inside the javascript/application.js:

myModal.addEventListener('shown.bs.modal', () => {
myInput.focus()
})
