Multiple file upload with jQuery, Rails 4 and PaperclipIn a recent project I needed a convenient file uploader. I wanted multiple file upload and progress bars. I wanted everything to work well together with Bootstrap. I needed jQuery File Upload. On first look it didn't seem to be trivial to include and after a search I found that Ryan Bates did a railscast on jQuery file upload. Unfortunately this railscast used Rails 3 and an older jQuery version.
