Re: a clean_tarfile() for my form

2008-12-23 Thread Alan

Sorry guys, apparently I found a solution, but...
Well I swear I tried it before, but now it's working. I did this:

try:

   tarfile.open(fileobj=file)

except:

   raise forms.ValidationError(msg2)

Anyway.

Cheers,
Alan

Re: a clean_tarfile() for my form

2008-12-23 Thread Alan

Hi,
Thanks for the hint, however, they only applies to tar archive file (give by
path) and not to 'file objects' as you get from "file =
self.cleaned_data['file']" in django models.

More specifically, how to make class tarfile to
handle django.core.files.uploadedfile.InMemoryUploadedFile objects.

Any help is always welcome. Thanks in advance,
Alan

Hi,
look at the module reference at python documentation:
http://www.python.org/doc/2.5.2/lib/module-tarfile.html
You can see there an is_tarfile to check if it is a tar file, or you can
use TarFileCompat to check if it is a tar_gzipped file.

a clean_tarfile() for my form

2008-12-23 Thread Alan

Hi There,
So I have a form where users can upload zip and tgz file. In my def
clean_file() for class MyForm, I can clean zip files smoothly and now I am
trying the same for a tgz file but missing things.

First, fileobj = self.cleaned_data['file'] will return a fileobj, so I
tried:

tar = tarfile.open(fileobj=fileobj)

but then I cannot do anything with 'tar'. I mean, tar.list() returns
nothing. Even worse, my fileobj can be any thing, a 'zip' for example, and
tarfile.open doesn't seem to check for that as it does if it was a file like
'myfile.tgz' or 'myfile.zip', failing to open for the former.

I tried google and also StringIO, but without success. All I want is to
check if the supposed tgz file is a valid tgz file as I do for a zip file.

Many thanks in avance,
Alan
