#compute_asset_path(source, options = {}) ⇒ Object

Overrides the built-in ‘ActionView::Helpers::AssetUrlHelper#compute_asset_path` to use the external asset pipeline, in the same manner that sprockets-rails does: github.com/rails/sprockets-rails/blob/v3.2.1/lib/sprockets/rails/helper.rb#L74-L96

def compute_asset_path(source, options = {})
  manifest = external_asset_pipeline_manifest
  asset = manifest.find(source)

  options[:host] = asset[:host] if asset && asset[:host]

  return asset[:path] if asset
  return super if manifest.fall_back_to_sprockets?

  raise AssetNotFound,
        "The asset #{source.inspect} is not present in the asset manifest"
end

#external_asset_pipeline_manifest ⇒ Object

This helper method can be overridden to return a different Manifest instance, e.g. to have distinct instances in different rails engines.
