I just started to use twitter-boostrap gem for my simple app.
When I check it loads some many javascript file which I believed it does not use in a particular page. just like show in the following image

So the question, is it possible to manage which js file should be loaded in a page?
Thanks.

I have to embed an existing HTML project (a directory that was exported from another service including HTML files, gifs, and pngs) in a Rails app. These files should only be viewable by authenticated users, so I can't put them in /public.
Do I have to write a controller and convert all the existing HTML files (of which there are many) to rails views to get all the routing and auth to work and serve the assets via the asset pipeline? Or am I missing a less time-intensive solution? I'm worried that the HTML may change not-infrequently and I don't want to get stuck replicating this process often.
If you did not need to authenticate the user, then you would be able to serve them over the /public folder. But I think you will need controllers since you want to authenticate.
You will need to create controllers and views. It should not be too hard as you won't need to do a lot of custom erb.
Then just add a authenticate user before method to all pages you wanted authentication for.
I downloaded a onepager from the internet. This includes a html file with a lot of assets (seperate css, javascript and image files). It is a bootstrap theme so I know I can delete those css files from bootstrap.
What is the most clean way to implement this? I don't want those assets loaded when people are using the app itself. It is only needed for the landing page.
I know I can put it in the vendor folder. Problem here is still everything gets loaded.
Can somebody put me on the right track?
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.
I've got a simple rails gem (created using bundler) and I'd like to extend it by adding some CSS and javascript functionality. However, I'm unsure how to go about this and where to add the files. In particular, I need need more information on how it all fits together with the asset pipeline once it gets included in another project.
Can anyone give me the lowdown on how this works and either provide some simple examples or link to a tutorial? Literally 1 css and 1 js file is all I'm looking to include. Thanks.
You could write the gem as an engine. This allows you to have an app folder in the gem just as any Rails application would have. You can add models, views, controllers, assets etc.
Once you have it set up it's quite intuitive and it's a familiar way to create a gem if you're used to creating Rails apps.
This should get you started:

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

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)
