Hi,
Some time ago I had to validate ODT files sent to server via admin
site. Since I know how long it took me to solve that problem and I
haven't found any hints in google I decided to share with my solution.
Take have a look on my code:
import zipfile
try:
from cStringIO import StringIO
except:
from StringIO import StringIO
class ODTField(models.FileField):
def __init__(self, verbose_name=None, name=None, upload_to='',
**kwargs):
super(ODTField,self).__init__(verbose_name, name, upload_to, \
validator_list = [self.isODTFile])
def isODTFile(self, field_data, all_data):
try:
tmp = StringIO(field_data["content"])
zf = zipfile.ZipFile(tmp,"r")
if zf.read("content.xml")< =0:
raise ValidationError, _('Document must be \
in OpenDocument
format.')
except:
raise ValidationError, _('Document must be in OpenDocument
format.')
The most importatnt part of code is passing the argument
validator_list = [self.isODTFile] into argument list of __init__.
Btw. I started with my friend site about python and python related
stuff in polish. If you speek polish and have some time:D take have
look on it http://www.pydev.pl
