What's this?

asset_path(source, options = {}) public

Computes the path to asset in public directory. If :type options is set, a file extension will be appended and scoped to the corresponding public directory.

All other asset *_path helpers delegate through this method.

asset_path "application.js"                     # => /application.js
asset_path "application", type: :javascript     # => /javascripts/application.js
asset_path "application", type: :stylesheet     # => /stylesheets/application.css
asset_path "http://www.example.com/js/xmlhr.js" # => http://www.example.com/js/xmlhr.js
