Hi All,
I'm trying to allow some flexibility for my end users. I want to
support the uploading of multiple file archive types (tar.gz,
tar.bzip2, zip, rar etc).
I want to use python-magic to guess the filetype from the files magic
number and then use the appropriate decompression modules to get at
the data in the files.
Basically, I'm not sure how to make the type of the
request.FILES['datafile'] be compatible with the requirements of
python-magic (which needs a file-location or a string)
I have a view:
def upload_file(request):
c ={}
c.update(csrf(request))
if request.method == 'POST':
frag = request.FILES['datafile'].read(65536)
ft = magic.from_buffer(frag)
res = {}
res.update({ "result" : ft })
res.update({ "datafile" : type(request.FILES['datafile']) })
res.update({ "frag" : type(frag) })
return render_to_response("simple.html", {'content': res })
else:
form = UploadFileForm()
return render_to_response('upload.html')
"simple.html" just outputs the data structure "res", as below.
{'content':
{'datafile': <class
'django.core.files.uploadedfile.TemporaryUploadedFile'>,
'frag': <type 'str'>,
'result': 'empty'}}
I've tried different combinations of magic.from_file and
magic.from_buffer and both read() and chunk() from the
TemporaryUploadedFile object but I either get a type error or an
"empty" result. I think the above should work fine!
Using python-magic on the temp object that's been uploaded (and saved
to disk 'cos is > 2.5MB) works with both
magic.from_buffer(open("f").read(65536)) and magic.from_file("f").
Any ideas?
(also, anyone have any quick drop in helper methods for debugging I
can use instead of the horrible "res" dict I'm using?)
Thanks in advance
Wa
