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.

Parameters

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.

Returns

String

The path to the asset.

Examples

asset_path(:javascript, :dingo)

=> "/javascripts/dingo.js"

asset_path(:javascript, :dingo, true)
# => "public/javascripts/dingo.js"
