Hmm: My relevant codes seems to be:
@login_required def upload(request): if request.method == "POST": form = ExcelUploadForm(request.POST, request.FILES) if form.is_valid(): request.session['sheet'] = form.cleaned_data["excelfile"] If I put something boring into the session (like a string, instead of the form.cleaned_data item), the problem goes away. If I leave that last line as it is, it comes back... David -- You received this message because you are subscribed to the Google Groups "Django users" group.
