Rails 4, asset pipeline causes user downloadable files to be downloaded twice

Question

I have a folder in my app directory named \"uploads\" where users can upload files and download files. I don\'t want the uploads folder to be in the public directory becaus

Answer 1

For anyone having this problem, I solved it. Pass

'data-no-turbolink' => true 

into the link_to helper to stop Turbolinks from messing with the download.

Answer 2

But if you are using a form with turbooboost = true, instead of link_to, or even with a link_to you can do it like this:

Inside your controller, and inside your action put:

def download
      respond_to do |format|
        format.html do
          data = "Hello World!"
          filename = "Your_filename.docx"
          send_data(data, type: 'application/docx', filename: filename)
        end
        format.js { render js: "window.location.href = '#{controller_download_path(params)}';" }
      end
  end

Replace controller_download_path with a path to your download action,

and place in your routes both post and get for the same path:

post '/download'  => 'your_controller#download',  as: :controller_download
get '/download'  => 'your_controller#download',  as: :controller_download
