sass-rails' asset helper functions (font-url, font-path, image-url, image-path, etc.) pass their full argument along to sprockets to look up in the sprockets manifest. When the argument is a URL that concludes with a query string or an anchor tag, neither sass-rails 3 nor sprockets 2 strips it before looking up the digest. This results in sprockets not finding the digest, and the non-digest URL is used instead.
This issue occurs in sass-rails < 4, and it is resolved by this gem. For later versions of sass-rails, this gem is unnecessary.
Add this line to your application's Gemfile, in the same group as sass-rails:
gem 'sass-rails-query_string_and_anchor_fix'And then execute:
$ bundle
Or install it yourself as:
$ gem install sass-rails-query_string_and_anchor_fix
After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
