I'm using sass imports to handle most of my styles for our rails 3.2 app. My application.css.scss file looks like this:
application.css
/*
*= require_self
*= require_tree ./vendor
*= require admin
*/
admin.css.scss
// Reset
#import "global/reset";
// General Variables
#import "admin/general/_variables";
// Main Elements
#import "admin/general/_typography";
// Layout
#import "global/_layout";
#import "admin/general/_gridset";
// Modules
#import "admin/modules/_table";
#import "admin/modules/_forms";
#import "admin/modules/_buttons";
// Styles
#import "admin/_style-clean";
#import "admin/_style-images";
// Features
#import "admin/features/features";
Error message: Sass::SyntaxError - Undefined variable: "$body-bg".
(in /var/www/apps/dev_wbs/releases/20130624191222/app/assets/stylesheets/admin/_style-clean.css.scss)
_variables.css.scss (imported) contains $body-bg, and it is referenced in _style-clean.css.scss
I originally had this in the sass syntax, but every time we push to the dev server, we get an error of Sass::SyntaxError - Undefined variable: "$body-bg". The variable is declared in the variables file, and the error comes from the _style-clean scss file. I've dropped this variable into the style-clean file, but then I get another variable error, but it refers to one in the typography file, which is above the style-clean, making me think somehow that the assets are being pre-compiled and then added.
I'd like to go back to using sass syntax, but both scss and sass throw variable errors.
All individual files are currently in the format of: _variables.css.scss.
Any help would be appreciated!
The asset pipeline relies on application.css to tell it what files to include. Changing it to SASS probably wouldn't allow that to work.
Also, your application.css needs to tell Ruby where to look for files:
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the top of the
* compiled file, but it's generally better to create a new file per style scope.
*
*= require_self
*= require_tree .
*/
If you put the code you pasted in your question into a new file like global.css.scss and recreate the application.css in /app/assets/stylesheets/ you should be off to the races both with the above code and SASS styles as well.

I am trying to require "font-awesome.scss" in the application.css of my Rails 4 app like this:
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.
*
*= require 'font-awesome.scss'
*= require_tree .
*= require_self
*/
'font-awesome.scss' imports a bunch of files that look like partials, with a preceding underscore. One of these partials (_variables.scss) defines a variable that I need to define as of the moment I get the following error message:
Sass::SyntaxError (Undefined variable: "$fa-css-prefix".
(in /Users/bla/rails_projects/Homepage/app/assets/stylesheets/_bordered-pulled.scss:4)):
app/assets/stylesheets/_bordered-pulled.scss:4
app/views/layouts/application.html.erb:35:in `_app_views_layouts_application_html_erb__3531690645719711557_70221015865520'
What am I doing wrong?
Just do this:
*= require font-awesome
No need to put the quotes or extension.
More docs on the subject here: http://guides.rubyonrails.org/asset_pipeline.html
you can use font awesome without the gem, just use their cdn.
This goes in your layout, application.html.erb
<head>
...
<link href="//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.css" rel="stylesheet">
...
</head>
More info here: http://fortawesome.github.io/Font-Awesome/get-started/
Try checking how you are precompiling assets. Check initializers/assets.rb (or it may be environments/production.rb for you) to make sure you are precompiling assets in a friendly way, like this:
config.assets.precompile += ["*.js", "*.scss", "*.jpg", "*.png"]
I was having this same error when it was
config.assets.precompile += [/.*\.png/,/.*\.ico/,/.*\.jpg/,/.*\.js/,/.*\.scss/]
There is the following code application.css.scss:
#import "bootstrap-sprockets";
#import "bootstrap";
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.
*
*= require_tree .
*= require_self
*/
.table tbody > tr > td.vertical-align {
vertical-align: middle;
}
This file is in 'stylesheets' directory. There is also 'home.css.scss' file in the same dir. But if I move this style from 'application' file to 'home' file browser doesn't see this style. What's the trouble? How can I fix it? Thanks!
in my case I have imported bootstrap at the end of the file followed by styles, this must be the problem
*= require_tree .
*= require_self
*/
#import "bootstrap-sass-official/assets/stylesheets/bootstrap-sprockets";
#import "bootstrap-sass-official/assets/stylesheets/bootstrap";
.table tbody > tr > td.vertical-align {
vertical-align: middle;
}
also I'd say you should try to put require tree after require self:
*= require_self
*= require_tree .
this makes more sense.
From the Rails Asset Pipeline docs:
If you want to use multiple Sass files, you should generally use the Sass #import rule instead of these Sprockets directives. When using Sprockets directives, Sass files exist within their own scope, making variables or mixins only available within the document they were defined in.
http://guides.rubyonrails.org/asset_pipeline.html
So in your case you can move the styles you declared in application.css.scss into a separate file (say: table_styles.css.scss) and then rewrite your manifest file as:
#import "bootstrap-sass-official/assets/stylesheets/bootstrap-sprockets";
#import "bootstrap-sass-official/assets/stylesheets/bootstrap";
#import "table_styles";
// Import any other files that would have been imported by require_tree
The advantage of this approach is that you can use sass variables and mixins and you have better control over the load order of your stylesheets.
I have a rail 4 project with "stylesheets/application/index.css.scss" with my all css files:
/*
*= require jquery.ui.all
*= require_tree ../shared
*= require_tree ../design
*= require_tree ../layout
*= require_self
*= require_tree .
*/
rails compile all css in only one, minimized (in prod).
I need to import #import "shared/header" in many files.
exemple: in "stylesheets/layout/main.css.scss"
#import 'shared/header';
.header
{
#extend .header_common_overview;
[...]
}
but I #import 'shared/header' in others files too. The result is :
when rails compile in only one file, there are many times the same rules ".header_common_overview", because I import it in different files.
I tried to put the "import" instruction directly in index.css.scss, but it does't works.
So how can I import only one time a file, and be abble to call the content in all others files?
First, don't use require_tree . You lose control over the include order of your CSS files, potentially leading to cascading issues - styles being overwritten that really should not be.
I've learned to avoid sprockets' require lines in the main SASS files for reasons similar to what you describe.
It can lead to duplication, particularly when using =require_tree all over the place
Variables/mixins/etc... can't be included via sprockets (I'd love to be proven wrong about this though)
In your index.css.scss you might consider simply putting
#import "vendor";
#import "shared";
#import "design";
#import "layout";
// Your main styling here.
#import "another_file";
These #import lines correspond to other sass files. shared.css.scss for example might look like
/*
*=require ./shared/header
*/
The idea is to
Keep clean separation/organization of your asset includes
Explicitly define each asset include so you retain full control over include order
Use SASS #importinstead of Sprockets =require directive to keep variables, mixins, etc... present in an included file available throughout.
My solution is : create all.css.scss with :
/*
*= require jquery.ui.all => static, don't need import
*/
#import 'included/**/*'; //all files included (at first time)
#import 'all/**/*'; //all real css files which requires included file (in second times)
The order is respected and controlled.
The included files is present only one time
the included files are shared in each real css files.
thx for help.
I cant seem to figure out what i am doing wrong. I have added custom files. I have tried to override the current ones.
application.css.scss
#import 'bootstrap-sprockets';
#import 'bootstrap';
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or vendor/assets/stylesheets of plugins, if any, can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any styles
* defined in the other CSS/SCSS files in this directory. It is generally better to create a new
* file per style scope.
*
*= require_tree .
*= require_self
*/
i should be able to just add another style sheet correct?
What i had to do was add
#import '<insert file name here>'
It then worked.
I am followed the directions on the workflow from this post, but I am getting the following error:
Undefined variable: "$zindex-navbar".
(in /Users/thalatta/code/aviary-hours/app/assets/stylesheets/_navbar.scss)
Here is the stack trace:
app/assets/stylesheets/_navbar.scss:13
app/views/layouts/application.html.erb:7:in `_app_views_layouts_application_html_erb___2018644895263320512_70131537402780'
app/controllers/application_controller.rb:25:in `block in <class:ApplicationController>'
Now the variable $zindex-navbar is most definitely in my _variables.scss partial. Here is it in the file:
$zindex-navbar: 1000 !default;
which is in my app/assets/stylesheets dierectory and is #imported by my bootstrap.scss file
in the following line:
#import "variables";
which, bootstrap itself is imported by my application.css.scss file here:
#import "bootstrap";
Now my concern is that it is not loading all of my dependencies properly and I am not sure how that happened.
application.css.scss
/*

*= require_self
*= require_tree .
*/
#import "bootstrap";
Is the problem that the application.css.scss is of .scss extension and therefore is not called in the stack trace from application.html.erb? How can I properly set up my assets to load the built in dependencies that twitter-bootstrap has (i.e. all of the #import <partialname> lines in the bootstrap code)
Thank you so much for your help.
Ever yours,
Micha'el.
