So I'm keeping uploaded files in an S3 bucket. For private documents,
their S3 permissions are set to private. So my plan has been that
Django will check if a user is authenticated, and if so, pull the
document from S3 and send it to the client. I'm using the boto S3
library to do the actuall interactions with S3 (that's what all the
get_key stuff is based on below). This functions are:
@login_required
def priv_document(request, itemid):
from myapp.media.models import Document
import mimetypes
d = get_object_or_404(Document, pk=itemid)
f = get_from_s3(d.file_key)
mtype = mimetypes.guess_type(d.file_key)
resp = HttpResponse(f, mimetype=mtype[0])
resp['Content-Disposition'] = 'attachment; filename=%s' %
d.file_key.split('/')[-1]
return resp
def get_from_s3(skey):
import tempfile
k = get_key()
k.key = skey
f = tempfile.TemporaryFile(mode="wb")
k.get_contents_to_file(f)
f.seek(0)
return f
However, I'm getting a corrupted file. When I did `diff origfile.pdf
downloadedfile.pdf` I found the following error inserted into the
file:
> <pre>

I thought I had found a discussion that linked this error to threading
in python - but I can't seem to find it again. Any ideas you have on
how to resolve this would be appreciated...
