I've got a Ruby on Rails app running with Bootstrap, which I installed using the gem twitter-bootstrap-rails.
I'd now like to integrate a new Bootswatch theme, but I'm having trouble figuring out what to do.
There are four possible downloads for each theme - a bootstrap.css file, a bootstrap.min.css file, a variables.less file, and a bootswatch.less. My question is: do I need to download and add them ALL to my ~/app/assets/stylesheets folder? or do I just need a subset of those? Currently inside ~/app/assets/stylesheets are just two files: application.css and boostrap_and_overrides.css.less. LESS really throws me off here so I'm totally confused with how it works and what I need to do to add new css files with this setup. Any help is appreciated.
You only need to download the bootstrap.css file, and rename it. The bootstrap.min.css is the same as the css file just a minified version of it. Less is just another way of writing css and accessing each property differently. Check out less. Add css file and begin integrating into html, also point html to new stylesheet.
Here's a twitter bootstrap gem for easy Bootswatch theme integration/customization for rails:

How can I use a theme from Bulmaswatch in my rails app? I'm currently using the bulma-rails gem. Bulmaswatch recommend using their CDN but how to get it work with the asset pipeline? What's the simplest easier way to get it done?
(Supposition is you have routes, controllers, views sorted)
Add the bulma gem (cdn not needed)
Add any number of Boostrap gems that play well with sass
Bundle
Add #import "bulma"; into application file
Restart the server
IMHO the easiest way is:
Under app/assets/stylesheets delete application.css and create a new file called application.css.scss
Then in that file copy paste the code from your favorite theme on bulmaswatch.
There you go, you've got a unique theme working in bulma.
This question is somewhat similar to: How to customize bulma variables in rails
I have a project of Rails 4 integrated with bootstrap.
I use less-rails-bootstrap gem in order to integrate it.
I wonder what is the best way to integrate bootstrap into rails without using less (os sass). I assume I can simply download the css and js files as explained in the bootstrap site, but I wonder if i might have problems with it.
Yes, if you don't want to customize Bootstrap styles, you can simply download it from bootstrap site and put it under vendor folder.
And you won't have problems, since Rails will precompile the files (js/css/img) under vendor folder.
Make sure to read this answer if you add fonts too.
I found a nice template online and want to use it for my rails app homepage. I decided to use the high voltage gem and read through its readme. I managed to get the routing right but I could not find the appropriate path/folder for the numerous asset (css, js, svgs and sass) files which come inside the template zip file, and which obviously make it look nice.
I tried putting them into the assets folder of my rails app, which got some of the "features" working, but svgs and images didn't display... and it screwed my existing pages. Reading through the Rails documentation I then tried storing the template assets into the vendor folder, which did not work either.
Where should I store the assets for my template-inspired homepage for them not to screw the appearance of my normal/app pages? Which paths should I use in my html to call them?
If you have troubles with images, take a look at image references in the template source. You can see a reference to image like this :
background-image: url('images/top-1280.svg')
which would not serve this image in Rails.
I would suggest to find and replace all the image references in your css (or scss) files.
Try this :
background-image: url(image-path('top-1280.svg'));
which is the proper way for Rails 4.
The differences:
in Rials you have a helper method "image-path" and you do not prefix the image file with directory name.
It is important to check in your "app/assets/stylesheets/appilcation.css" if there are lines like:
*= require_tree .
*= require_self
Now about Font Awesome : I see that in this theme you are about to use Font Awesome. I would suggest using the gem for Rails:
In your Gemfile:
gem 'font-awesome-sass'
I think the theme you have chosen is very nice. Thank you for sharing it, it will be useful for my current project.
The website https://wrapbootstrap.com/ has themes which were made using Twitter Bootstrap. Each of these themes include different versions of Twitter Bootstrap along with other various libraries and versions (jquery, fontawesome, etc...)
How do I add these themes to my existing Rails app? What are the steps?
I'm especially curious about the conflicts that may arrise if I'm already using a different version of jquery, twitter bootstrap, fontawesome, and others (as declared in the Gemfile).
Thank you
You can add the css from the theme you purchased from wrapbootstrap to your assets > application.css.scss file. And use the html tags that came with the theme in your rails app views so that the css styling is applied.
Also, I would recommend using gem 'sass-rails' to import the standard bootstrap styling.
Here's a tutorial to get you started with adding bootstrap to a rails app. Adding the theme css and html tags is up to you.
http://railscasts.com/episodes/328-twitter-bootstrap-basics?view=asciicast
I did this for few of the projects, I agree with majorly what Mike has answered above. Here are some of the gotchas I saw.
We started as a standard project on Rails all our views dynamic(Ember)/static were based on Bootstrap CSS. When major internal pages were up and functionality demonstrated we focused on landing pages. By this time we had the gems for bootstrap, fontawesome added to our Gemfile.
So one of the thing is to remove these gems "bootstrap", "fontawesome" from Gemfile. Include these as part of your wrapbootstrap dump.
Also as you progress with integration you may realize that a lot of common code is being repeated, its in your best interest to split the page components: headers, footers other things as partial Rails views. It severely saves the editing effort.
Another thing I found extremely useful to keep every thing up while you are still in integration stage, is to split your CSS/JS includes for pages imported from wrap bootstrap and pages you already have. So if you intend to migrate all existing pages into new theme scraping your CSS, then it can be merged in stages, otherwise you can let them co-exist.
You have to add new entries in routes.rb, controller calls to support the pages if you don't have them already. Likes of about, contactus, team etc. etc.
And if you use something like Ember/Backbone then you have to manage the co-existence of single pager app in some pages which may or may not be linked to the Wrapbootstrap pages.
This was all the things I had to take care off when I integrated the wrapbootstrap theme on top of Rails-EmberJS app.
Interesting timing as I just had to do this myself. I'm still fairly new to Rails so this might not be the best solution, but here's how I got it working ...
Note: every theme is different so this may not be a one size fits all approach.
1) My theme was built with Middleman and it was expecting to run stand alone or on a Sinatra instance.
2) In order to get the theme up on Rails, I had to add the compass gem, the sass gem, the sass-rails gem, and the compass-rails gem to work properly. I'm assuming you can install these (if required for your theme).
3) Assuming you have a Rails app ready to roll, go into your assets directory and backup your .js, .css, and all fonts and images. Place your theme asset files in the appropriate place.
4) Now do the same with your view layer. You may have a partials and/or pages folder which you can place in the views directory. You'll want to put application.erb.html and any navigation files in the layouts folder under the views directory. Again, make sure you back up your original files first.
5) If your theme was designed for Sinatra, you may have a Config.rb file. I moved the logic from this file into my config/environment.rb file. I was the least confident with this step. Other Rails devs can chime in if there is a better location.
6) Start your server up. You may encounter some exceptions but this is to be expected.
7) Take a look at your old app/assets/javascripts/application.js file and compare it to the new file. Ensure that the new file has the jquery ujs library included //= require jquery_ujs . Without this bit of magic your PUT and DELETE HTTP verbs won't work properly.
8) Path adjustments. My theme had the Font Awesome library included. In order to get it to work, I had to adjust the reference paths at the top of the font-awesome.scss file.
9) Finally, you'll need to debug the newly added code in the environment.rb file. The Sinatra developer was doing a lot of Route magic to adjust the navigation display. This wasn't porting over well to my environment. I removed many of these calls from my navigation template files. Once complete, my newly skinned app was up and running! Good luck.
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 youe new theme.

I'm trying to find the twitter-bootstrap files in my rails app ('bootstrap-sass', '2.0.0'), as I need to make a change directly to the bootstrap-responsive.css file, however, I can't find it.
I have bootstrap up and running, but can't seem to find the bootstrap files. How do I locate the bootstrap-responsive.css file?
Thank you!
The bootstap-sass gem uses the Rails 3.2 asset pipeline to inject the necessary stylesheets into your app. The actual stylesheet files are located in the gem installation directory, not in your project itself.
Depending on what you want to change, you can either:
Copy the _bootstrap-responsive.scss file from the gem into your app/assets directory and edit it there.
Customize the necessary Bootstrap variables before loading up Bootstrap in your application.scss file:
$btnPrimaryBackground: #f00;
#import "bootstrap";
Edit: Try looking under
app/assets/stylesheets
Here's an example
https://github.com/joliss/solitr/tree/master/app/assets/stylesheets
I'm not too familiar with the structure of rails apps but did you create a local copy or are you using the bootstrap files being hosted directly by github? You should be able to figure that out by checking one of your launched html pages and viewing the source, looking for something like
<link rel="stylesheet" href="http://twitter.github.com/bootstrap/1.3.0/bootstrap.min.css">
If it's a local page, there should be a directory somewhere in your rails app where the files are stored - perhaps there's a 'static' folder or something similar? Try file-searching for it, good chance you might find it.
(I use Django/Python for web projects but I'll look into Rails a bit and see if I find anything)
