Hey guys,
I'm trying to make a view so that my users can download a compressed tar
archive. I've seen a ton of examples about downloading files yet cannot
seem to find anything regarding tar. Anyone want to drop me an awesome
example?
for a simple file I have
def download_file(request, pk):
my_model = SomeModel.objects.get(pk=pk)
file_path = my_model.get_file_path()
if os.path.exists(file_path):
with open(file_path, 'rb') as fh:
response = HttpResponse(fh.read(), content_type="")
response['Content-Disposition'] = 'inline; filename=' + os.path.
basename(file_path)
return reponse
There isn't anything special about serving different types of files. The
only trick is to specify the correct MIME type if you know it (which you do
in this case, application/x-tar). Then it's just a matter of using inline
or attachment (recommended) for the content disposition header.
https://docs.djangoproject.com/en/1.11/ref/request-response/#telling-the-browser-to-treat-the-response-as-a-file-attachment
https://docs.djangoproject.com/en/1.11/howto/outputting-csv/#using-the-python-csv-library
Or better yet, hand the file transfer off to the web server process, where
it belongs.
