This is my first stackoverflow question..
I'm trying to install Boostrap 4 on Rails 5, I thought that everything was working but when I checked the website from mobile I noticed that the navbar is really small compared to the "usual" size (but at least it's correctly collapsed).
I followed the official "Bootstrap Ruby Gem"but it doesn't work.
This is the current website with the incriminated navbar (it's just the basic navbar from boostrap components):
https://warm-peak-79199.herokuapp.com/
Following my files:
GemFile:
gem 'bootstrap', '~> 4.0.0.beta2.1'
Application.scss:
// Custom bootstrap variables must be set or imported *before* bootstrap.
#import "bootstrap";
Application.js:
// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, or any plugin's
// vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.

//= require rails-ujs

Your site is missing the responsive meta tag. Add this to your layout inside the <head> tags:
<meta name="viewport" content="width=device-width, initial-scale=1.0">

The examples on the Bootstrap 5 site only show non-LI nav items aligned to the right.
I have 4 menu items, 3 should be left aligned while the last should be pushed to the right.
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container-fluid">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">

You could achieve this with the classes .me-auto on the left div or .ms-auto on the right div. This adds a margin between the two different navigation elements. Here a short demo, but you can see some other examples with a searchbar in the navbar-documentation.
Changed navbar-expand-lg to just navbar-expand so the example is easily visible without needing to go fullpage.

Note that these changes would not have any visual effect on the mobile version of the navigation. Also, if you are using e.g. divs or lists (ul/ol) for the navigation will not make any visual difference with bootstrap. However, it could make an impact in SEO and accessability.
I am getting started with learning Ruby On Rails and I already learned I had to change my application.html.erb layout name to default.html.erb. Now I am trying to add a navbar to the layout, but it does not seem to be activating. The navbar will show up in individual pages, but the default layout stays the same. This is what I currently have in the code so far:

Any feedback on what I could be missing in the code or am I possibly missing an installation in the ruby-on-rails server I developed?
I am new to rails development. I am creating one Rails app. In which I am using Bootstrap 4.0.0 beta. I have one navbar in particular div, (not on whole page). But problem is, dropdown is not working when I click on it. For that first I have to click on nav-brand first, then I can click on dropdown and it works. But it changes whole placings of navbar. and again if I click on nav-brand dropdown stops working.
I also tried putting it on whole page there is also same problem.
I have ruby-2.4.1, rails-5.1.3, bootstrap-4.0.0beta
Here is my /assets/stylesheets/application.css code
*= require bootstrap
And this is /assets/stylesheets/welcomeindex.css code
*= require bootstrap
*= require application
body, .jumbotron{
height: 100vh;
min-height: calc(100vh - 155px);
//overflow: hidden;
}
.jumbotron{
margin-bottom: 0px;
}
#media (max-width: 991px) {
.jumbotron{
height: 100%;
}
}
.footer {
position: fixed;
bottom: 0;
width: 100%;
height: 40px;
line-height: 40px;
background-color: #f5f5f5;
.container {
width: auto;
max-width: 680px;
padding: 0 15px;
}
}
This application.js file:
//= require jquery
//= require jquery_ujs
//= require popper
//= require turbolinks
//= require bootstrap-sprockets
//= require bootstrap
//= require_tree .
And this is welcomeindex.html.erb file:
<html>
<head>
<title> Fest Management </title>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= stylesheet_link_tag 'welcomeindex', media: 'all', 'data-turbolinks-track' => true %>
</head>
<body>
<div id="main-container" class="container-fluid">
<div class="row">
<div class="jumbotron col-lg-8 col-md-12">
</div>
<div class="jumbotron col-lg-4 col-md-12">
<nav class="navbar navbar-light bg-light">
<div class="navbar-header">
Brand
</div>
<div id="navbarCollapse">
<ul class="nav navbar-nav">
<li class="dropdown">
<a data-toggle="dropdown" class="dropdown-toggle" href="#">Messages <b class="caret"></b></a>
<ul class="dropdown-menu">
<li>Inbox</li>
<li>Drafts</li>
<li>Sent Items</li>
<li class="divider"></li>
<li>Trash</li>
</ul>
</li>
</ul>
</div>
</nav>
</div>
<footer class="footer navbar-fixed-bottom">
<div class="container">
<span class="text-muted">Place sticky footer content here.</span>
</div>
</footer>
</div>
</div>
</body>
</html>
So where am I missing? It would be great help.
EDIT
after solving the issue of dropdown click, I am getting the issue with CSS of navbar. when i expand dropdwon, rather than poping out of navabar area, it increases the height of navbar and shows whole list in it.
here is the edited index.html.erb file. Along with the edits suggested I have completely removed CSS references and still it giving the same problem for CSS.
<div id="main-container" class="container-fluid">
<div class="row">
<div class="jumbotron col-lg-8 col-md-12">
</div>
<div class="jumbotron col-lg-4 col-md-12">
<nav class="navbar navbar-light bg-light">
<div class="navbar-header">
Brand
</div>
<div id="navbarCollapse">
<ul class="nav navbar-nav">
<li class="dropdown show">
<a data-toggle="dropdown" class="dropdown-toggle" href="#" id="CategoryDD" aria-haspopup="true" aria-expanded="false">Messages <b class="caret"></b></a>
<ul class="dropdown-menu" aria-labelledby="CategoryDD">
<li>Inbox</li>
<li>Drafts</li>
<li>Sent Items</li>
<li class="divider"></li>
<li>Trash</li>
</ul>
</li>
</ul>
</div>
</nav>
</div>
<footer class="footer navbar-fixed-bottom">
<div class="container">
<span class="text-muted">Place sticky footer content here.</span>
</div>
</footer>
</div>
</div>
Adding to application.js
//= require jquery-ui
right after
//= require jquery
worked for me like a charm.
Hopefully, this will solve someone's issue too.
You shouldn't add body and html tags in a view. You also shouldn't add
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
All of this is usually already defined in application.html.erb which is the "skeleton" of your views.
Regarding your issue:
According to the documentation, you're missing an id on the a tag.
<div class="dropdown show">
<a class="btn btn-secondary dropdown-toggle" href="#" role="button" id="dropdownMenuLink" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown link
</a>
<div class="dropdown-menu" aria-labelledby="dropdownMenuLink">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
Try removing any custom classes you've added and simply use this snippet. Should work out of the box if you leave all their elements.
If it still doesn't work, try running this in your console:
$('.dropdown-toggle').dropdown()
And let us know if there is an error.
You have added bootstrap but not jquery. Since bootstrap depends on jquery you must also add it. Before Rails 5, jquery used to be default in Rails app but Rails team removed it after Rails 5. If you want to use it then you should add this gem to your Gemfile. Here is the link https://github.com/rails/jquery-rails
Same issue, but solved with this kind of doing...
Did you overwrite bootstrap CDN or install any kind of bootstrap things like example of:
<!-- CSS only -->
<link href="https://cdn.jsdelivr.net/npm/bootstrap#5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
<!-- JavaScript Bundle with Popper -->
<script src="https://cdn.jsdelivr.net/npm/bootstrap#5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script>
If you're having this kind of in application.html.erb then kindly remove all kind of this...
and clear all cdn links and add again bootstap link
Thank you.
I just moved over to Bootstrap 4 and noticed some weird behavior in my app. All of the navbar links work fine on the first try, including the dropdowns, but after the linked page loads, all of the navbar links are dead. They come alive again when I reload whatever page I happen to be on.
My code:
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<a class="navbar-brand" href="/" style="color:white">
... some content
</a>
<button class="navbar-toggler" type="button" data-toggle="collapse"
data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="navbarSupportedContent">
<ul class="navbar-nav mr-auto">
<li class="nav-item dropdown">
...
</li>
<li class="nav-item dropdown">
...
</li>
</ul>
</div>
</nav>
Is this a known issue with Bootstrap 4, or am I seeing something else?
When I posted my original question, I didn't specify that this was a Rails 5 application.
Originally, I had tried to load bootstrap using the CDN links provided at the bootstrap site:
<head>
...
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous">
...
</head>
<body>
...
<script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/js/bootstrap.min.js" integrity="sha384-h0AbiXch4ZDo7tp9hKZ4TsHbi047NrKGLO3SEJAg45jXxnGIfYzk4Si90RDIqNm1" crossorigin="anonymous"></script>
...
</body>
I wrestled with this for some time and couldn't solve the problem. It seemed that none of my javascript-related bootstrap components (e.g. popovers) worked unless I reloaded the page.
In the end, I gutted all of this and opted for the bootstrap-ruby gem. When I followed the implementation instructions, everything worked fine.
I'd still be interested in knowing why the CDN solution didn't work.
I have bought a twitter bootstrap theme from wrapbootstrap.
I already have a functional rails application. Now, I want to design my application by integrating the bootstrap theme into my application.
I am new to this and I have no idea how to do it. After doing a lot of research on this, I found only a very few discussion regarding this issue. As for example I found this post: Implementing WrapBootstrap theme into Rails App
But, I am not totally sure how the assets from the theme will be applied to my application. I have copied all the assets under my project's app/assets/images, app/assets/javascripts and app/assets/stylesheets folders from the theme's corresponding folders. Then, I got several error when I tried to run my app locally. I deleted my application.css file, after that it started working. But, I can not see any design from the theme being applied yet. What should I do to make this theme work into my rails app?
First check this screencast:
http://railscasts.com/episodes/328-twitter-bootstrap-basics
then I would add a bootstrap gem like bootstrap-sass, then add the JS files through the gem by adding them to the manifest, something like this:
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require_tree .
then i would get the css files that you bought from wrapboostrap and place them in you assets/stylesheets folder, then add the necesary markup and clases to your app this is how ive done it before.
hope it helps
EDIT:
Markup:
Check the template you downloaded, lets start with the navbar for example
Code from template:
<header>
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</a>
<div class="container">
<a class="brand" href="index.html">Gaia Business</a>
<div class="nav-collapse">
<ul class="nav">
<li class="active">Home</li>
<li>About</li>
<li>Service</li>
<li>FAQ</li>
<li>Contact</li>
<li class="dropdown">
Dropdown <b class="caret"></b>
<ul id="dropdown-menu" class="dropdown-menu">
<li>Dropdown 1</li>
<li>Dropdown 2</li>
<li>Dropdown 3</li>
<li class="divider"></li>
<li class="nav-header">Nav header</li>
<li>Dropdown 4</li>
<li>Dropdown 5</li>
</ul>
</li>
</ul>
</div><!-- /.nav-collapse -->
</div><!--/.container-->
</div><!-- /navbar-inner -->
</div>
</header><!--/header-->
Now you need to place yourself in your app, if the navbar shows in every view on your app, you should mention it on the layouts/application.html.erb something like this:
<!DOCTYPE html>
<html>
<head>
<title>Golden Green Chlorella</title>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<%= render :partial => 'layouts/navbar' %>
<%= yield %>
</body>
</html>
and last, do your navbar partial
_navbar.html.erb:
<header>
<div class="navbar navbar-fixed-top">
<div class="navbar-inner">
<a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
<span class="icon-bar glyph"></span>
<span class="icon-bar glyph"></span>
<span class="icon-bar glyph"></span>
</a>
<div class="container">
<%= link_to "Your app", root_path, :class => "brand" %>
<div class="nav-collapse">
<ul class="nav">
<li class=<%= current_page?(static_index_path) || current_page?(root_path) ? "active" : "" %> > <%= link_to (t "navbar.home"), root_path%></li>
<li class=<%= current_page?(static_know_path) ? "active" : "" %>> <%= link_to (t "navbar.know"), static_know_path%></li>
<li class=<%= current_page?(static_buy_path) ? "active" : "" %>> <%= link_to (t "navbar.buy"), static_buy_path%></li>
<li class=<%= current_page?(static_faq_path) ? "active" : "" %>> <%= link_to "FAQ", static_faq_path%></li>
<li class=<%= current_page?(static_contact_path) ? "active" : "" %>> <%= link_to (t "navbar.contact"), static_contact_path%></li>
<!-- <li class="active">Home</li> -->
</ul>
<ul class="nav pull-right">
<li><%= link_to "English", static_english_path%></li>
<li><%= link_to "Español", static_spanish_path%></li>
</ul>
</div><!-- /.nav-collapse -->
</div><!--/.container-->
</div><!-- /navbar-inner -->
</div>
</header><!--/header-->
That was only for the navbar, now you need to do the rest, add the markup your template shows you to do, with all your app, its not an easy job, but thats how its done.
make sure that while installing twitter bootstrap you should add following gem into your Gemfile under "group :assets"
gem 'therubyracer'
gem 'less-rails'
gem 'twitter-bootstrap-rails'
then run bundle command.
Now, the theme "file_name.css" (file_name could be any) that u have downloaded just add it into "stylesheets" folder under app->assests->stylesheets
then open your application.css file in same folder there you will see
*= require_tree.
replace this line with
*= require "file_name.css"
NOTE: Don't forget to re-compile your assets or simply delete the content of your tmp/cache folder.
save it and reboot your server. it will apply your new theme.
