Дата создания отчета не включена

Я пытаюсь сгенерировать отчет в pdf в Django, но дата отчета не отображается. Как можно включить дату отчета fromdate и todate в заголовок PDF после сохранения дат в модели? Есть ли что-то, что я упустил?

Пожалуйста, смотрите ниже коды. Спасибо

View.py

try:
    if request.method == 'POST':
        fromdate = request.POST.get('fromdate')
        todate = request.POST.get('todate')
        report = GenerateReport(user=request.user, fromdate=fromdate, todate=todate, report="Accident Causation PDF")
        report.save()
        
    print(fromdate, todate)

    # incident_general_accident = IncidentGeneral.objects.filter(user_report__status = 2).values('accident_factor__category').annotate(Count('severity'), filter=Q(severity='Damage to Property'))
    incident_general_accident = IncidentGeneral.objects.filter(status = 2, date__range=[fromdate, todate ])
    incident_general_accident1 = IncidentGeneral.objects.filter(status = 2,severity='Fatal', date__range=[fromdate, todate ] ).annotate(Count('severity'))
    incident_general_accident2 = IncidentGeneral.objects.filter(status = 2,severity='Damage to Property', date__range=[fromdate, todate ] ).annotate(Count('severity'))
    incident_general_accident3 = IncidentGeneral.objects.filter(status = 2,severity='Non-Fatal', date__range=[fromdate, todate ] ).annotate(Count('severity'))
    incident_general_classification = IncidentGeneral.objects.filter(status = 2, severity="Damage to Property", date__range=[fromdate, todate ]).distinct('accident_factor')
    incident_general_collision = IncidentGeneral.objects.filter(status = 2, severity="Damage to Property", date__range=[fromdate, todate ]).distinct('accident_factor') #you can filter using order_id as well
    
    
    report1 = GenerateReport.objects.all().order_by('-created_at')[:1]
