'NoneType' object has no attribute 'strftime'

Question

views.py

def when(request):
    user = request.user  
    try:
        report = Report.objects.get(user=user.id)
    except:
        report = None
    settings = Settings.objects.get(user=request.user)
    settingsForm = SettingsForm(instance=settings)
    if settings.date_format == '0':
        date = report.manual_date.strftime('%d/%m/%Y')             
    else:
        date = report.manual_date.strftime('%m/%d/%Y')        
       reportform = ReportForm(instance=report)
    if request.method == 'POST':
        reportform = ReportForm(request.POST,instance=report)
        if reportform.is_valid():
            report = reportform.save(commit=False)
            report.user = request.user
            report.save()
            return redirect('/member/media/')
    reportform = ReportForm(instance=report,initial={'manual_date':date})

The above code is used to convert and show the date format.Initially,i hard coded the value in database and checked about format change.Now,for 1st time,for new record in database,it is giving this error "'NoneType' object has no attribute 'strftime'"

I don't know how to logically handle this.Need your help.

Thanks

You would have to handle the check for both report and report.manual_date for None

Try this:

def when(request):
    user = request.user
    date = None  
    try:
        report = Report.objects.get(user=user)
    except:
        report = None
    settings = Settings.objects.get(user=user)
    settingsForm = SettingsForm(instance=settings)
    reportform = ReportForm()
    if report and report.manual_date:
        if settings.date_format == '0':
            date = report.manual_date.strftime('%d/%m/%Y')             
        else:
            date = report.manual_date.strftime('%m/%d/%Y')        
        reportform = ReportForm(instance=report)

    if request.method == 'POST':            
        reportform = ReportForm(request.POST)
        if report:
            reportform = ReportForm(request.POST,instance=report)

        if reportform.is_valid():
            report = reportform.save(commit=False)
            report.user = request.user
            report.save()
            return redirect('/member/media/')
    reportform = ReportForm(instance=report,initial={'manual_date':date})

I don't know how to logically handle this

manual_date = report.manual_date

if (manual_date):
    format =  (settings.date_format == "0") ? '%d/%m/%Y' : '%m/%d/%Y'
    date = manual_date.strftime(format)

else:
   #No report.manual_date

"Most likely your report object is None". No. If that were the case, the error message would say "NoneType object has no attribute manual_date".

thanks.. but the code would not work if report is None anyways.. I edited it now.
