Question

I am using the send_file method to download a file. It works fine on my local machine. But it’s not working on the server – it returns a blank file.

code:

send_file Rails.root.join('public', 'uploads') + (uploaded_file.original_filename + ".filtered")

Please help.

Depending on what web server you are using, you may have to change the sendfile settings in your config/environments/production.rb.

For example, for nginx, you need to uncomment out this line:

config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect'
