Instance Method Details

#asset_path(asset_type, filename, local_path = false) ⇒ Object

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<Symbol>

Type of the asset (e.g. :javascript).

filename<~to_s>

The path to the file.

local_path<Boolean>

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"
