Hi Daniel,
you should see:

<http://docs.python.org/library/bz2.html#module-bz2>or
http://docs.python.org/library/gzip.html#module-gzip
Hello Juliom, thanks for reply.
I have of course seen both of these before I sent the mail,
unfortunately I couldn't figure out how to use it on my
InMemoryUploadedFile object.
But basically you should import the compress function from the library
and use it.
<http://docs.python.org/library/gzip.html#module-gzip>from bz2 import
compress
[...]
def handle_uploaded_subtitles(self, files):
for file in files:
sub_file = SubtitleFile(file_name=file.name, etc)
bz_file = compress(file)
I wish it would be that easy :-)
What you are proposing fails with Exception:
bzfile = compress(file)
argument 1 must be convertible to a buffer, not InMemoryUploadedFile
Further, I wasn't able to find a method in the mentioned libraries that
would make this possible, or at least I didn't figure out how to pass an
InMemoryUploadedFile to them to compress it.
When I try to do this:
file.write(zlib.compress(file.read()))
sub_file.file.save(file.name, file)
that does not seem to compress it's content, the file gets saved, but
when I run file(1) on it, it doesn't recognize it as a gzip file and
neither gzip(1) does. When I compare the original file and the new file
with diff(1) it's the same but, there are a few additional bytes at the
end of the new file (I don't think it's a compressed content as it's too
few bytes.)
I also tried:
gzipfile = gzip.GzipFile(fileobj=file)
sub_file.file.save(file.name, gzipfile)
however, that fails for me with this exception:
'NoneType' object is not subscriptable
which comes from
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/gzip.py
in __init__:
if mode[0:1] == 'r':
So do you have any more specific ideas how to accomplish what I am
trying to do?
Thank you.
sub_file.file.save(file.name, bz_file)
Regards,

Hello all,
I am uploading some text files through django (using a form
FileField), and I am getting InMemoryUploadedFile objects this way.
In my handle_uploaded_subtitles() method, which gets the list of
InMemoryUploadedFile objects, I would like to compress these files
(so that I will get either gzip or bzip2 file, and then save it to a
FileField model field.
Currently, I have a this code:
def handle_uploaded_subtitles(self, files):
for file in files:
sub_file = SubtitleFile(file_name=file.name
<http://file.name>, etc)
# here I need to compress the file
sub_file.file.save(file.name <http://file.name>, file)
Does anyone here have an idea how can I accomplish this?
Thanks!
