I have installed normalise-rails gem in my project and it all seems to work fine.
But I notice there is no css file generated in the app and I'm curious to know how this is working.
This is not a problem and such but it will be good to know what has happened in the background.
Look, to make it work you added to application.css these lines:
*= require_self
*= require normalize-rails
*= require_tree .
And middle line just requires normalize-rails.scss file that you can found in gem's vendor/assets/stylesheets directory.
That's because the gem isn't downloaded in your project. All the gems are installed in your INSTALLATION DIRECTORY - more info.
If you want to use an edited version of normalize.css, then just download the stylesheet and save it in your app's
vendor/assets/stylesheets/
folder and include that file in your
app/assets/stylesheets/application.css
, like:
/*
*= require_tree .
*= require normalize
*= require_self
*/

I have ruby on rails project in which I want to include scss files in my style sheets that is application.css
The directory structure is look like below:
The problem is that when I try to do this in my application.css file:
*= require font-awesome
*= require bootstrap
*= require slick
*= require basic-theme
*= require style
*= require_self
#import url("style.scss"); //it is in scss folder.
it still does not parse the code in it. Also if I set the path with assets/ it does load it but gives error like:
Sass::SyntaxError in Home#index
Undefined variable: "$base-font".
How I can easily import all these scss files in my rails app? Also any best practices please?
Instead you need to use
#import "<relative path to style.css without .scss>"
I have a LESS-based rails application.
since I added summernote html editor, I had to add also SASS code to my project.
So I added these lines:
Gemfile:
gem 'font-awesome-rails'
gem 'summernote-rails'
gem 'bootstrap-sass'
application.css:
*= require font-awesome
*= require summernote
In local everything works fine.
When I commit the application to heroku I get the following error:
Sass::SyntaxError: Undefined variable: "$alert-padding".
(in /tmp/build_xxx/vendor/bundle/ruby/2.1.0/gems/bootstrap-sass-3.3.1.0/assets/stylesheets/bootstrap/_alerts.scss:10)
I guess I miss the SASS variables, but have no idea how to add them without create any conflict with the LESS code.
============= EDIT =================
The precompilation is broken on the first sass variable it finds, in file /gems/bootstrap-sass-3.3.1.0/assets/stylesheets/bootstrap/_alerts.scss:
.alert {
padding: $alert-padding;
I assume the precompiler does not have any SASS variable declared, and fails to precompile on the first place it finds any.
============= EDIT =================
I added to my application.scss the #import I understand I needed to have, now it looks like this:
#import "bootstrap-sprockets";
#import "bootstrap/variables";
#import "bootstrap/mixins";
#import "bootstrap";

*= require jquery.fileupload-ui
*= require font-awesome
*= require social-buttons-3.css
*= require summernote
*/
I definitely have _variables.scss included (I renamed it in order to be sure), and I see that $alert-padding is declared:
$alert-padding: 15px !default;
$alert-border-radius: $border-radius-base !default;
$alert-link-font-weight: bold !default;
Still, I get this error!
PD -
I use the following command in order to check precompilation locally:
RAILS_ENV=development bundle exec rake assets:precompile
You can find installation instructions here.
I fail to see at least those:
application.css should be application.scss
gem 'sass-rails' in your Gemfile
use the import statements accordingly and appropriately in your application.scss
I am trying to install my first gem in Ruby, but am having problems with it working. I am not quite sure where I am going wrong, I am following the directions of the gem step by step. I am using Cloud9 for my ide.
The gem I am trying to install is the: wysiwyg-rails gem
I add the following line to the gem file:
gem 'wysiwyg-rails', '1.2.5'
then I add the following to the application.css file so it looks like:
/*
*= require froala_editor.min.css
*= require froala_style.min.css
*= require font-awesome
*= require_tree .
*= require_self
*/
And finally I add the require .js file to the application.js:
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require froala_editor.min.js
//= require plugins/tables.min.js
//= require_tree .
I run bundle install and then restart the server. When I try to load the page, I get the error: couldn't find file 'font-awesome'
However, i can see that font-awesome is installed
Using font-awesome-rails 4.2.0.0
If I remove the *= require font-awesome from the application.css, it starts up without any errors. When I view the source code, I can see the css and js files ( froala_editor) load up, but font-awesome is not one of them. Is there a step that I am missing?
Thanks!
the problem is very strange,the reason is unknown,but i resloved in my program,just add "font-awesome-rails" gem.
gem "font-awesome-rails"
Have you tried installing with font-awesome-less or font-awesome-sass gems to get them up and running?
It seems you are running without any sprockets (asset-pipeline). Add any of those gems, it probably run fine when serving rails s.
After bundle install, go to application.css and write this code as it follows:
#import "font-awesome-sprockets"
#import "font-awesome"
Hope that helps.
I've updated my app to use the rails 3.1 asset pipeline (I think). I can compile .css files but not css.scss. I am running the sass-rails gem but nothing seems to work.
What should I check? Sorry, I don't know exactly what info I should supply here to help debug. I can edit this...
EDITS:
My .scss file contains:
/*
*= require_self
*= require_tree .
*/
edit:
see Sprockets::CircularDependencyError in Store#index
Thanks,
Rim
Remember that css.scss files need to be included, not imported like the rest:
So: Turn you application.css into an application.css.scss, and do like this in it:
/*
*= require ./normal/custom.css
*= require_self
*/
#import "normal/design/control_panel";
This was asked in another question, but none of the solutions appear to work for me in 3.1rc1.
I'm trying to use the new assets stuff in rails 3.1 - I have the files:
./vendor/assets/stylesheets/jquery-ui-1.8.13.custom.css
./vendor/assets/javascripts/jquery-ui-1.8.13.custom.min.js
I then added:
//= require jquery-ui to app/assets/javascripts/application.js
*= require jquery-ui to app/assets/stylesheets/application.css
The jquery-ui javascript file loads just fine, but the css file says:
Sprockets::FileNotFound (couldn't find file 'jquery-ui'
(in /home/xanview2/xancar/app/assets/stylesheets/application.css):6):
Any ideas?
Example of a working setup:
$ cat app/assets/javascripts/application.js
//= require jquery
//= require jquery-ui
$ cat app/assets/stylesheets/application.css
/*
*= require vendor
*
*/
$ cat vendor/assets/stylesheets/vendor.css
/*
*= require_tree ./jquery_ui
*
*/
vendor/assets/ $ tree
stylesheets
vendor.css
jquery_ui
jquery-ui-1.8.13.custom.css
...
images
jquery_ui
ui-bg_flat_0_aaaaaa_40x100.png
...
Finally run this command:
vendor/assets/images $ ln -s jquery_ui/ images
Enjoy your jQuery UI
This is a great article to read about Rails 3.1's asset pipeline and jQuery UI: JQuery-UI css and images, and Rails Asset Pipeline
You might have more luck with the jquery-ui-rails gem (see announcement), which packages the jQuery UI JavaScripts, stylesheets and images as assets for you.
This topic comes up a lot, and now that a significant amount of time has passed, things may be different.
In Rails 3.1.2, I found something that works without symbolic links.
Follow the steps above, but put the images for the theme right next to the jquery-ui-xxx.css file in an images/ folder. This saved me quite a few headaches.
Yes, this would mean the images would reside in a stylesheets/ folder in vendor/assets, but it works and it is quick to do.
Have you tried using the rails-asset-jqueryui gem? It vendors jquery-ui and the standard themes (currently v1.8.16) and makes them available via the asset pipeline. The following example calls for the Smoothness theme.
Gemfile:
....
gem 'rails-asset-jqueryui'
...
app/assets/javascripts/application.js:
...
//= require jqueryui
...
app/assets/stylesheets/application.css:
...
= require smoothness
...
If you're using the jquery-ui-rails gem:
application.css
/*
*= require jquery.ui.all
*/
application.js
//= require jquery.ui.all
It seems to me that a lot of confusion can be avoided by keeping these library assets out of assets/javascripts and assets/stylesheets dirs, where sprockets et al have some opinions about what should happen.
Say you've downloaded a customized jquery-ui zipfile from the themeroller. Try this:
unpack the zip file into an subdir of an assets dir, something like
vendor/assets/jquery-ui-1.8.23.custom
in application.rb add:
config.assets.paths << Rails.root.join('vendor', 'assets', 'jquery-ui-1.8.23.custom').to_s
add manifest files in the usual places:
vendor/assets/javascripts/jquery-ui.js:
//= require_tree ../jquery-ui-1.8.23.custom
vendor/assets/stylesheets/jquery-ui.css:
*= require_tree ../jquery-ui.1.8.23.custom
in config/environments/production.rb, add (referring to manifest filenames):
config.assets.precompile += %w(jquery-ui.js jquery-ui.css)
in views:
<%= stylesheet_link_tag 'jquery-ui' %>
<%= javascript_include_tag 'jquery-ui' %>
if you use this:
https://github.com/carlhoerberg/sprockets-urlrewriter
i believe you can just dump the whole shebang in a directory and require the css file... it will smoothly rewrite the relative urls.
you just have to install the gem and add a config line to application.rb
