How to render fully-qualified image asset url from mailer layout template?

[krsyoung]

Hello, I'm currently testing vite_ruby as a replacement for webpacker, which in general has been an absolute dream!

I have one issue that I'm not finding information on and was curious what others thought. We have a mailer.html.erb layout which contains an image file. Previously we had used the asset_pack_url so that we would get a fully qualified url to the asset and the image would render correctly in email clients.

It doesn't appear that the same exists within vite_ruby? vite_asset_path works as expected, but doesn't include the FQDN and thus doesn't render correctly. I tried vite_asset_url but it doesn't exist (was worth a shot).

Have others run into this and maybe there is a different helper method that I'm missing?

Thanks!

Hi Christopher! @krsyoung

The best approach is to configure asset_host, which will be used implicitly by tag helpers in Vite Rails.

Duh, thanks! Turns out I had the perfect combination of not testing the right thing.

I needed to add a config.asset_host to development.rb and things look good (production.rb has the correct value for asset_host but was using the old asset_pack_url tag).

Long story short, you're awesome! 👍
