This might perhaps be a simple question, but I somehow just can not find the solution. Django offers a lot about uploading file, but how do I do to download a file.
Let's assume we have a button on HTML on uploads/something.txt as a file.
I tried with django.views.static.serve, however what this did it would open a file on webpage.
My question is simple: What is the best and most pythonic way for user of our website to download a file?
HttpResponse along with proper content type. Here's some sample code:
content = open("uploads/something.txt").read()
return HttpResponse(content, content_type='text/plain')
This should serve a text file.
But as you described, on some browser, it will not ask to download the file, rather, it would show it in the browser. If you want to show a download prompt, use this:
response = HttpResponse(open("uploads/something.txt", 'rb').read())
response['Content-Type'] = 'text/plain'
response['Content-Disposition'] = 'attachment; filename=DownloadedText.txt'
return response
However, please note that it might be a better idea to serve static contents or uploaded files via nginx or the reverse proxy of your choice. Sending large files through Django might not be the most optimum way of doing that.
import os
from django.conf import settings
from django.http import HttpResponse, Http404
def download(request, path):
file_path = os.path.join(settings.MEDIA_ROOT, path)
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type="application/vnd.ms-excel")
response['Content-Disposition'] = 'inline; filename=' + os.path.basename(file_path)
return response
raise Http404
Maybe a little late but here is my solution:
def render(self, value):
return format_html('<a href="/media/{0}" download>{0}</a>', value)
