tempfile.TemporaryFile is what you seem to want. The file object is
deleted automatically.
fd = tempfile.TemporaryFile()
fd.write(odt_data)
fd.seek(0)
return HttpResponse(
fd.read(),
content_type='application/vnd.oasis.opendocument.text'
)
But then you might as well skip the tempfile feature, and stream
directly from memory:
return HttpResponse(
odt_data,
content_type='application/vnd.oasis.opendocument.text'
)

Since your odt data is for one-time-only usage, you don't need to put
them in any kind of STATIC_FILES directory. That feature is of use to
offload download performance to the web-server, but for one-time-only
downloads there is no point.

Done already by the tempfile.TemporaryFile class, and totally redundant
when streaming from memory.
