relative_url_root doesn't work correctly with Rails 5.1.4

Hello.

I faced 404 errors for asset pipeline URLs when I set config.relative_url_root with Rails 5.1.4/

What I did was as follows.

  1. Put the following lines in development.rb.

ENV[“RAILS_RELATIVE_URL_ROOT”] = “/subdir”

config.relative_url_root = “/subdir”

  1. Modified config.ru as follows.

map ActionController::Base.config.relative_url_root || “/” do

run Rails.application

end

  1. Then start rails server

rails server puma -d -b 0.0.0.0

  1. See the application application page

http://localhost:3000/subdir

Some of asset URLs get 404 error and not shown.

Of course, commenting #1 works well.

Could you please advice how to fix this?

Someone, please try to do above as it’s easy to setup…

Thanks,

I guess asset compile is failing with relative_url_root… Any bugs reported?

see config.assets.prefix

Thanks. Already tried. But the option changes asset directory under public. It made the situation worse… (all of assets becomes 404)

Finally solved. The root cause was config.assets.debug = true in development.rb.

When I commented it, it worked!

The conclusion is config.assets.debug has a bug with relative_url_root.

Thanks,
