CodePudding user response：

You should check whether the file has been updated or not, then do things accordingly, if updated then save that one, otherwise old file should be there.

Try this view:

def EuAdmin(request, pk):
    pi = EmailDb.objects.get(id=pk)
    if request.method == 'POST':
        institution = request.POST.get('institution', '')
        fullname = request.POST.get('fullname', '')
        email = request.POST.get('email', '')
        contact = request.POST.get('contact', '')
        position = request.POST.get('position', '')
        uploadd = request.FILES.get('upload', '')
        pi.institution = institution
        pi.fullname = fullname
        pi.email = email
        pi.contact = contact
        pi.position = position
        if uploadd:
            pi.uploaddata = uploadd
        pi.save()
        return HttpResponseRedirect("/eadmin")
    return render(request, 'NEC/eupdate.html', {'pi': pi})
