I'm working on a Ruby on Rails app that is using Webpacker. I get a strange undefined method error when using asset_pack_path - a NoMethodError is thrown and says undefined method 'asset_path' Did you mean? asset_pack_path. This is a similarly named method but not the one I am calling; asset_path does not appear in the app's codebase either.

I believe to be calling the correct path inside of asset_pack_path but that does not seem to be consistent with the error. Perhaps there is a versioning mis-match somewhere? I am at a loss with this one. Any ideas or suggestions to resolve this undefined method error and use asset_pack_path would be helpful. Thanks!

You are trying to call Rails Views helper method inside a Controller.

Try: ActionController::Base.helpers.asset_pack_path

No idea why, but I needed ActionController::Base.helpers.asset_pack_path("media/images/logo.png") - it refused to work for me without the media/images/ part, even though logo.png was inside images/, not in any special place. I figured out what it wanted by running bin/webpack in the terminal and looking at the output. Hope it helps someone.

It turned out that asset_path was called inside the asset_pack_path method - both ActionView::Helpers::AssetUrlHelper Webpacker::Helper need to be included for asset_pack_path to work
