Question

I\'m using the PDFkit in my controller to build out a series of PDFs, zip them up, and then send them to the user.

The best way to get the compiled name is from the manifest that is generate when you compile.

You can make a controller method that serves the raw name in development, and then accesses the manifest in production to map the correct name.

The location of the manifest by default is:

File.join(Rails.public_path, config.assets.prefix, 'manifest.yml')

But it looks like you can access this as a hash at config.assets.digests

config.assets.digests[css_file_name_as_string]
