The flow looks like that:

1. user is filling the form
2. form is passed to the server by ajax
3. form is saved to db, then the pdf with the form data is created and saved in the app folder (probably a bad move here...)
4. ajax success causes the page to append a button 'Download' with value equal to current pdf's name so button 'Download' appears to the user
5. If user presses the button the very pdf that was just saved is gonna download.
6. Refreshing the page makes the button disappear.

I've got stuck on point 5. I have created another ajax (to avoid reloading the page) bound to the Download button. It correctly asks the server to look for the file, creates a django File object: pdf_file = File(open(file_path, 'rb')) and creates a HttpResponse with file, and content_type='application/pdf' or 'application/download'. response['Content-Disposition'] is attachment.

Then the ajax returns response - only it does not. Server raises no error but ajax error function is called.

I've read that downloading with ajax is not possible. Could you help me a bit to get it straight? If above snippets are not clear, I shall provide more code. Python 3.5, Django 1.10
