Down here's the code in which I'm creating a zip file with a bunch of pdf
labels, and returning it on the HttpResponse for the user to DL it.
The weird thing is that I'm getting just a pdf file (ok, I'm testing with a
single file, so I don't know if that's the problem) and I can't set the
downloaded filename to anything (it's always "download")
Can someone see what I'm doing wrong?
files = []
for detail in queryset:
for parcel in
detail.parceldescription_set.select_related().all():
shipment = parcel.shipment
if not shipment.label:
try:
shipment.download_label(args['username'],
args['password'])
except Shipment.Wait:
self.message_user(_("Failed downloading label for "
"shipment {id} because the "
"Canada Post server is busy, "
"please wait a couple of
minutes "
"and try again").format(
id=shipment.id))
files.append(shipment.label.file)
tmp = tempfile.mkstemp(suffix=".zip")
tf = zipfile.ZipFile(tmp[1], mode="w")
for file in files:
filename = os.path.basename(file.name)
tf.write(file.name, filename)
tf.close()
return HttpResponse(open(tmp[1]), mimetype="application/zip")
