bootstrap-rubygem | Bootstrap 4 rubygem for Rails / Sprockets / | Application Framework library

Everything was fine before adding Bootstrap to the project. Now I am getting ActionController::UnknownFormat error. I was using jquery in my project before(added with yarn). But when installing Bootstrap, I also installed jquery for it with a gem. Maybe there can be a problem in there. Thanks for helping.

comments_controller.rb

just getting started with a Rails 5 side project. Having some issues getting an out of the box Navbar showing correctly.

It's all squished up, as per the screenshot attached. Any thoughts?

I've attached the relevant code below.

Thanks in advance!

1. application.html.erb

I have a fully functional rails app with the bootstrap-rubygem (v4.3) installed.

In my app I have a partial that gets re-rendered when a remote: true link is clicked. When this link is clicked I have a controller that responds to JS and then in my .js.erb view I replace the html of a specific div.

Now in this partial view, I make use of tooltips & dropdown. The problem is, the tooltips only work after a hard refresh. As soon as I click to reload the partial remotely, the tooltips stop working. The exact opposite is true for the dropdowns. They don't work until I click on the remote link.

Have I missed anything in setting up this gem or am I perhaps making a mistake in the way I'm implementing bootstrap with JQuery & Turbolinks?

Main JS file: application.js

I was having trouble with one of my Ruby on Rails projects when I tried to upgrade from bootstrap 3. I removed the bootstrap-sass gem and followed the instructions on this github page, but whenever I requested a page from the server, I got an error about undefined variables for colors.

I made a new rails project, with the sole purpose to get bootstrap 4 working.

My Gemfile:

I'm running a Rails 5 application and am looking to implement Bootstrap for the front-end styling. Can't find a general consensus on the difference between these two gems: https://github.com/seyhunak/twitter-bootstrap-rails and https://github.com/twbs/bootstrap-rubygem

The first is more popular by downloads, but the second is maintained by the official Bootstrap team. The first also seems to have generators which would be handy, but if someone could explain the differences that would be great.

Thanks!

I have followed the bootstrap-rubygem setup directions. Everything works except when I try to access variables like $black and $white I get a Sass::SyntaxError of Undefined variable. I've been googling this for the past 4 hours. Is there something that I need to turn on? I used to do this successfully with rails 4.2 and bootstrap 3 years a couple years ago, but now I'm at a loss.

Gemfile

I'm currently using bootstrap 3.3.7 and trying to upgrade to 4.0.0.beta2 but after following this tutorial https://github.com/twbs/bootstrap-rubygem I receive the below error.

I am using Rails 5 with Twitter Bootstrap gem (Twitter Bootstrap 4.00.beta2.1). I am using Carousels and Grid system and everything works, but not navbar. I am using code for navbar for Bootstrap site Bootstrap site and is always in mobile state.

I tried with new page with Bootstrap not with bootstrap-rubygem, but from CDN and the navbar works fine. For the example in page with bootstrap-rubygem I see:

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/
