How to integrate Compass with Rails 3.1 asset pipeline

readme.md

This gist is no longer valid. Please see Compass-Rails for instructions on how to install.

Yeah, that's right. We experimented with using require, but that had its own problems.

I'm having an issue getting compass and blueprint to work with my project, even though I have followed all the steps... (all of this is in develop) Rails 3.1 Ruby 1.9.2

I originally installed compass, and then called compass init rails --using blueprint. It claimed it worked fine. I then went and relocated the stylesheets into the correct directory.

I have the standard partial called _base.scss inside its own partial folder and four stylesheets called
application.css.scss
ie.css.scss
print.css.scss
screen.css.scss
all are in the app/assests/stylesheets

I call each of them by using the stylesheet_link_tag '*.css'....
When running the rails server, it fails
Cannot find or import: blueprint/reset
So I go in and remove that clause, again,
Cannot find or import: compass/reset
...again
Cannot find or import: blueprint

and it goes on forever with me removing each line until nothing of
compass or blueprint is being called...

If I stop calling any stylesheet except application.css.scss, which is written in basic css with no compass or blueprint calls, the site runs fine. The second I add @import "blueprint";
the site crashes again saying cannot find or import blueprint.

Its as if compass and blueprint aren't really inserted into my project as it claims.

What am I missing?

I assume it's just a typo, but app/assests should be app/assets.

Yup, that's a typo... Though I wish it was something that stupid! haha

Found my issue. I had 0.11.5 installed!

I'll note here that trying this out with Rails 3.2.0.rc1 appeared as if compass wasn't loaded when I tried to include it at the top of my application.css.sass on a fresh Rails project. Downgrading everything back to rails ~> 3.1 worked for me. Just a heads up.

Edit: d'oh! Issue has already been opened.

Temporary fix for 3.2.0.rc1: make sure sprockets is declared above sass-rails in your Gemfile:

gem 'sprockets'
gem 'sass-rails'
gem 'compass', '0.12.alpha.2'

Asset pipeline fun continues...

Thanks, @bensie, that seemed to do the trick. What does that accomplish, do you know? I'm not extremely familiar with bundler, but does that make a certain version of sprockets a priority over what compass normally uses?

Sprockets was removed from the sass-rails Gemfile in rails/sass-rails@3c24e4f

While the reasoning behind it makes sense, there's clearly more work to be done to get the load order right.

This was fixed in rails/sass-rails@f8faec5

Not sure is anyone is running an issue upgrading from Rails 3.0 to 3.1.3 with Compass v0.12.alpha.4

File to import not found or unreadable: compass/reset.
Load path: Sass::Rails::Importer

Add this to your application.rb:

 config.sass.load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/compass/stylesheets"

Will fix this issue.

FWIW, with rails 3.2.0, there is no need to add sprockets to your Gemfile, and the following assets group works fine:

group :assets do
  gem 'sass-rails', '~> 3.2'
  gem 'coffee-rails', '~> 3.2'
  gem 'uglifier', '~> 1.0'
  gem 'compass', '~> 0.12.alpha'
end

This gist is no longer valid. Compass v0.12 release candidate is out and should make rails integration a snap. Please see https://github.com/compass/compass-rails for details.

@chriseppstein thanks for all your work on this!
