compass and sass-rails not working in 3.1.0.rc2?!

[mugwump]

I'm trying to get compass to run with 3.1.0.rc2/sass-rails: Previously (rails 3.1.0.rc1), I had a sass.rb in config/initializers, that made the compass-framework-scss available like this:

Sass::Engine::DEFAULT_OPTIONS[:load_paths].tap do |load_paths|
  load_paths << "#{Rails.root}/app/assets/stylesheets"
  load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/compass/stylesheets"
  load_paths << "#{Gem.loaded_specs['compass'].full_gem_path}/frameworks/blueprint/stylesheets"
end

That was already a bit hackish, but at least it worked - now with 3.1.0.rc2 and sass-rails I'm getting
'''
Sass::SyntaxError: File to import not found or unreadable: blueprint.
'''

for all the compass-stylesheets. If have seen, that sass-options are now set via config.sass.<option>- but the simplistic:

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

is not working, as config.sass.load_paths is nil. Any ideas how to feed sass-rails these additional paths?!

The following will work:

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

However, if you want to run with compass, please help test by installing from source:

gem 'compass', :git => 'git://github.com/chriseppstein/compass.git', :branch => 'rails31'

Compass will automatically initialize itself via a railtie.

yes, figured that one out: I thought that the load-path should already be set to something meaningful.

Thanks for the help, Chris: Switched to the rails31-branch and now things are working again without that hack. Apart from some strange behavior concerning partials, things seem to be working now.

The strange behavior: I had a partial in app/assets/partials/_colors.scss that contained some variable definitions (e.g. $grey: #e6e6e6;), and the import didn't work anymore (Sass::SyntaxError: Undefined variable: "$grey") until I changed the name to _colors.css.scss). Others partials though worked without the renaming...

Sprockets does the importing. I don't really understand what's going on there, but you should definitely name all your files .css.scss now.

Have the same issue as mugwump with undefined variables not being defined after importing a partial. Using Rails 3.1.0.rc4 and compass from github :branch=> 'rails31'
Renaming partials to .css.scss solves it.

[chriseppstein]

files have to be renamed to be part of the asset pipeline.
