Asset_sync gem跳过PDF文件

Question

I recently configured the asset_sync gem to sync all of my assets to Amazon S3. I deploy on Heroku, and for whatever reason, it seems to be skipping all PDF files in my /app/assets directory. I haven't told it to exclude any files, why might this happen?

I've followed this guide: https://devcenter.heroku.com/articles/cdn-asset-host-rails31 , and as such I don't have an asset_sync.rb initializer file.

I've tried moving the PDFs to their own dir, /app/assets/pdfs , and no dice there either.

Strangely, I have a .zip file in the /app/assets/images dir, so it seems like specifically PDFs are being skipped.

Rails 3.2.13, Ruby 2.0, Heroku Cedar Stack, current release of asset_sync gem

Answer 1

Turns out I had added *.pdf to my .slugignore file, and Heroku was tossing out the PDF files on deploy. DERP!
