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:
… 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
