sass-rails helpers “image-url”, “asset-url” are not working in rails 3.2.1

Question

I am on 3.2.1, with sass-rails-3.2.4 and sass-3.1.15...

The documentation for the asset pipeline says:

asset-url(\"rails.png\", image) becomes url(/a         


        

Answer 1

We just had the same problem and fixed it by explicitly requiring sprockets in the Gemfile (even though it's a dependency of ActionPack):

group :assets do
  gem 'sprockets'
  gem 'sass-rails', '~> 3.2.3'
  # ...
end

I don't know why, but it works now. ;-)

Answer 2

You might want to try clearing /tmp/cache. I am too new to Rails and Sass to know why this worked, but it solved the same problem for me after hours of searching.

BTW, this worked despite the fact that I could see other Sass directives, such as setting variables and calculating with them, being executed. I'm sure there is a very simple explanation, once I have time to track it down.

Answer 3

You can just add a trailing forward slash / to the path and use url like you usually do.

background-image: url("/assets/rails.png")
