Helpers for handling asset files.
Returns the URI path to a particular asset file. If local_path is true, returns the path relative to the Merb.root, not the public directory. Uses the path_prefix, if any is configured.
asset_type | Type of the asset (e.g. :javascript). |
filename<~to_s> | The path to the file. |
local_path | If true, the returned path will be relative to the Merb.root, otherwise it will be the public URI path. Defaults to false. |
String | The path to the asset. |
asset_path(:javascript, :dingo) # => "/javascripts/dingo.js" asset_path(:javascript, :dingo, true) # => "public/javascripts/dingo.js"
