pdfjs_rails's Issues

Not getting progress bar when PDF is being uploaded for previewing.

Unexpected server response (0) while retrieving PDF

I'm seeing this error after uploading PDFs to Amazon S3 w/ Paperclip. The PDF is there, and I'm able to access it fine by putting the URL into the address bar, but PDF.js just doesn't like it?

Unexpected server response (0) while retrieving PDF

Ticket Closed

On mobile devices the pdf gets downloaded

ActionController::RoutingError (No route matches [GET] “/pdf js/web/viewer.html”):

I'm using PDF.js in a rails application from https://github.com/shyammohankanojia/pdfjs_rails. I followed the instructions and everything works fine in development, but in production the viewer doesn't show the pdf.

I got the following error: "ActionController::RoutingError (No route matches [GET] "/pdf js/web/viewer.html"):".

I'm sure that pdf's are uploaded correctly in production. I ran bundle install and precompiled assets again. In development I didn't have to make any changes to routes.rb.

Any thoughts on how can i get the viewer to show the pdf in production?
