bower-rails can rewrite your relative asset paths

The asset pipeline changes the paths of CSS files during precompilation. This opens a world of pain when CSS files reference images (like jQuery UI) or fonts (like webfont kits from Font Squirrel), since all those url(images/icon.png) will now point to a broken path.

In the past we have been using the vendor/asset-libs folder as a good solution to work around this.

When you migrate to managing vendor assets in Rails with Bower, the bower-rails gem comes with its own solution for this problem. It can rewrite your .css files so all occurences of url(...) are replaced by something like url(<%= asset_path(...) %>) in a .css.erb file (code).

You can do this manually by invoking a Rake task:

rake bower:resolve

... or you can configure your application to automatically resolve paths before precompiling assets:

BowerRails.configure do |bower_rails| # Invokes rake bower:resolve before precompilation. Defaults to false bower_rails.resolve_before_precompile = true end

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
