Hello I am working a basic rails app, and I want to include a welcome page with a slideshow. How would I implement this in a Rails app? I am new to Rails, and I tried using Jquery, but it didn't work. I am also using bootstrap on my website.The problem is that the images wont load and I only see the arrow buttons and no images.
Thanks! Here is my code,
<script>
$(function(){
$('#myCarousel').carousel();
});
</script>
<div id="myCarousel" class="carousel slide">
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<!-- Carousel items -->
<div class="carousel-inner">
<div class="active item"><img src='pictwo.png'></div>
<div class="item"><img src='pictone.png'></div>
<div class="item">…</div>
</div>
<!-- Carousel nav -->
<a class="carousel-control left" href="#myCarousel" data-slide="prev">‹</a>
<a class="carousel-control right" href="#myCarousel" data-slide="next">›</a>
</div>
Twitter bootstrap incudes one, as well as provides examples on its usage - http://twitter.github.io/bootstrap/javascript.html#carousel.

Is there a built-in Bootstrap 4 trick that will align these three to centre, in a line "on a large screen", with a small space between them, then place them over each other when displayed on a small screen?
<h4 class="h4">Follow Social Media</h4>
<div class="row">
<div class="col-6-lg col-4-md col-1-sm center-pills">
<ul class="nav nav-pills">
<li class="nav-tabs">
<a class="nav-link active social social_f" href="#">Facebook</a>
</li>
<li class="nav-tabs">
<a class="nav-link active social social_i" href="#">Instagram</a>
</li>
<li class="nav-tabs">
<a class="nav-link active social social_y" href="#">Youtube</a>
</li>
</ul>
</div>
</row>
I've tried adding custom css but it keeps falling apart and looks messy.
At the moment, the code above output this:
Is there a build in bootstrap 4 trick that will align these three to centre
One of the first tricks is to use Bootstrap classes that actually exist.
col-6-lg col-4-md col-1-sm classes don't exist.
The next best trick is to replace your nav-tabs class with nav-item because the nav-tabs class isn't designed to be used the way you attempted to.
The mx-auto class needs to be added to the column to center it.
Finally, adding nav-justified to the parent element will do the trick of spreading the pills evenly. And for padding, you can use responsive padding classes px-lg-3 p-md-2 p-1.

I am using bootstrap from a CDN with my rails app. Most of the styling works except for the carousel on the home page. It works fine in development but not at Heroku. I don't know if this is relevant but I have defined this route in routes.rb: root "home#index" which displays index.html.erb via the HomeController. The first image in the carousel is loaded but that is it. It has no functionality. Right now I have no bootstrap gems in the gem file which I will try if necessary. I just wanted to see if anyone has seen this issue before and knows what to do. I think this file is OK since it works in development but here is index.html.erb:
<div id="myCarousel" class="carousel slide img-rounded" data-ride="carousel">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
<li data-target="#myCarousel" data-slide-to="3"></li>
<li data-target="#myCarousel" data-slide-to="4"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner" role="listbox">
<div class="item active">
<%= image_tag("nicholson2.jpg", alt:"nicholson", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("marilyn2.jpg", alt:"marilyn", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("pacino2.jpg", alt:"pacino", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("lily.jpg", alt:"lily", class: "img-rounded") %>
</div>
<div class="item">
<%= image_tag("deniro2.jpg", alt:"deniro", class: "img-rounded") %>
</div>
</div>
<!-- Left and right controls -->
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
<span class="sr-only">Next</span>
</a>
</div>
I resolved this by using https: instead of http: when linking to external resources. It works in development but evidently heroku does not allow it.
I had the same issue, in my case i had to remove the //=require jquery_ujs from the application.js file (assets/javascripts/application.js). Hopefully it will resolve the issue. :)
I am trying to make a slideshow using multiple photos that users uploaded through carrierwave.
This is my post/show.html.erb
<div id = "carousel-example-generic" class= "carousel slide" data-ride= "carousel">
<!-- Wrapper for slides -->
<div class="carousel-inner">
<% #photo_attachments.each do |p| %>
<div class="item active">
<%=image_tag p.avatar_url.to_s%>
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
<% end %>
</div>
.....
<script type="text/javascript">
$(function(){
$('.carousel').carousel();
});
</script>
I cannot figure it out the way to list one photo per slide:( It is still listing all the photos that I have to scroll :(
You are applying active class to all photos that you use
div class="item active"
but it should be
div class="item"
and add this into your javascript
$( '.item:first' ).addClass( 'active');
I'm still pretty new to coding, so I apologize if this is an easy fix. I'm using Ruby on Rails with the Bootstrap Gem.
I'm trying to set up a home page on my website that features an info box and sign up/sign in box with a background that is a three image carousel.
I've got the boxes set up with divs, but I can't get the images to fit the background. I'd like to have the images fade in, one after the other, but I'm stumped - any guides I've found so far are for earlier bootstrap versions.
Here is what I have currently.
<div id="myCarousel" class="carousel slide" style="position:relative;">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0" class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="item active">
<img src="sample.jpg">
</div>
<div class="item">
<img src="sample1.jpg">
</div>
<div class="item">
<img src="sample2.jpg">
</div>
</div>
</div>
Any suggestions would be greatly appreciated.
Thank you!
I am trying to use bootstrap's carousel inside an angular.dart component. Here is the html:
<div id="carousel" class="carousel slide" data-ride="carousel">
<!-- Indicators -->
<ol ng-repeat="pic in ctrl.pics" class="carousel-indicators">
<li data-target="#carousel" data-slide-to="{{ $index }}" ng-class="{ active: {{$first}} }"></li>
</ol>
<!-- Slides -->
<div ng-repeat="pic in ctrl.pics" class="carousel-inner">
<div class="item" ng-class="{ active: {{$first}} }">
<img src="{{ ctrl.pic.image }}">
<div class="carousel-caption">{{ ctrl.pic.title }}</div>
</div>
</div>
<!-- Controls -->
<a id="carousel-control-left" class="left carousel-control" href="#carousel" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
</a>
<a id="carousel-control-right" class="right carousel-control" href="#carousel" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
</a>
</div>
The prev/next controls don't work (maybe other things too), probably because the href attributes are wrong. I tried to fix them by updating the hrefs at run time, but I don't know how to enter a url pointing to an id that is inside shadow dom.
Alternatively, I tried to add event listeners that would use dart:js to call the carousel('prev') and carousel('next') bootstrap functions. This approach failed too because I don't know how to pass the shadow dom root reference from dart to javascript.
Any suggestions?
There may be two issues:
JavaScript tries to querySelect() an element and can't find it because it's hidden in the shadowDOM
you could change the JavaScript code
The CSS doesn't work because you haven't added applyAuthorStyles: true to your AngularDart component.
Currently Angular UI Bootstrap components are being ported to Angular Dart
see https://github.com/akserg/angular.dart.ui
Carousel is not yet working AFAIK
