`sthg`? What does that mean?

You cannot just get the file contents that easily. Here is the skeleton of
what I came up with after searching the web for examples:
# ----------------------------------------------------------------------- #
def _do_upload(self, req):
"""_do_upload(self, req)
Try to read and process data from the uploaded request.
Will redirect either to the details page...
...or the main list with an error message.
"""
gantt_file = req.args.get('GanttFile')
if not hasattr(gantt_file, 'filename') or not gantt_file.filename:
add_warning(req, "No License Request file specified.")
req.redirect(req.href.mainpage())
if hasattr(gantt_file.file, 'fileno'):
size = os.fstat(gantt_file.file.fileno())[6]
else:
gantt_file.file.seek(0, 2) # seek to end of file
size = gantt_file.file.tell()
gantt_file.file.seek(0)
if size == 0:
add_warning(req, "Request is empty?")
req.redirect(req.href.mainpage())
gantt_data = gantt_file.file.read()
<processing goes here>
Note: I run this on windows.

> data.update({

I hope that helps...
