Instance Method Details

#compute_public_path(source, dir, options = {}) ⇒ Object

Add the extension ext if not present. Return full or scheme-relative URLs otherwise untouched. Prefix with /dir/ if lacking a leading /. Account for relative URL roots. Rewrite the asset path for cache-busting asset ids. Include asset host, if configured, with the correct request protocol.

When :relative (default), the protocol will be determined by the client using current protocol When :request, the protocol will be the request protocol Otherwise, the protocol is used (E.g. :http, :https, etc)
