Thanks for this episode, this was really interesting !
I still have a question though, what about direct upload validations ? For example what if you want to make sure that your users can't upload files that are too big or what if you want to accept only "image/png" format? I believe this should be done at AWS S3 level as file are uploaded directly to S3 and not going through the Rails application. Do you know how to do this ?
