Django Fullcalendar Not rendering
I will get straight to the point. I'm using FullCalendar in mu application, and it's working fine, as aspected, but somehow, I have bugs when I try to render the calendar with ajax call, so the second time. When I call the landing page, the view, calendar gets rendered properly, but when I try to filter down the calendars using ajax implementation, the rendering is lost! I literally have no idea why is this happening, so any help will be great! The idea is simple, when I land on the page, I have all calendars rendered, and if I want to chose the particular calendar group, I just want to do a basic filtering depending on the users data. First, this is my function which handles the page : @login_required(login_url='registration/login') def add_event(request, pk): cal_group_param = request.GET.get('value_from_the_user', None) #Takes the users input from the frontend context = {} ... # Code which is nor relevant for this question ... events_all = Events.objects.all() if cal_group_param: calendars = Calendar.objects.all().filter( date_valid__gte=now.date(), calendar_master__group__cusopis=cal_group_param, ).order_by('date_valid') else: calendars = Calendar.objects.all().filter( date_valid__gte=now.date(), calendar_master__group__cusopis__icontains='default_group', ).order_by('date_valid') form = ZakaziForma() if request.method == 'POST': form = ZakaziForma(request.POST or None) if form.is_valid(): ... return redirect(success_page) context['cal_groups'] = cal_groups context['calendars'] = calendars context['form'] … -

get_field_display() does not return string after saving it
Hereby my (simplified) situation. When I change a choicefield from one to the other, I want to record a message saying "Field changed from (previous) to (new)" In parenthesis I'd like the actual label of the field, so in case of the example below that should be "Field changed from Open to Completed". However, for some reason I am only able to generate "Field changed from Open to 2" I am baffled why this happens given that I use the exact same code. Any ideas? class Task(Record): class Status(models.IntegerChoices): OPEN = 1, "Open" COMPLETED = 2, "Completed" status = models.IntegerField(choices=Status.choices, db_index=True, default=1) Then in my views I try to do this: if request.POST["status"] == 2: description = "Status changed from " + info.get_status_display() + " → " # This works fine, returning "Status changed from Open → " info.status = request.POST.get("status_change") info.save() description = description + str(info.get_status_display()) # Yet for some reason this fails, and I end up with an integer (2)! even though I use the same syntax -
