Rails 4 Amazon S3 background url images file not found

Question

Is there a way to make url in css to work with asset pipeline Like the one below?

background: url("../assets/pattern/black_paper.png")

I'm getting file not found and I'm using S3 and Heroku on Rails 4.

Answer 1

You need to:

1. Rename all your CSS files to css.erb

2. change your snippet of code to:

   background: url(<%= asset_path '/pattern/black_paper.png' %>)

Answer 2

Try

background: asset_url("pattern/black_paper.png");

It works for me without renaming CSS files.
