filtering

[DenisIschenko]

q = self.request.GET.get('q') if self.request.GET.get('q') else None may be replaced by q = self.request.GET.get('q', None)

Also i do not understand logic start_date = datetime.strptime(self.request.GET.get('startDate'), '%d.%m.%Y').date() \ if self.request.GET.get('startDate') else self.request.POST.get('startDate') basically if in get do not present date you get it from post, but do not convert to date

also logic if q != None and start_date == None and end_date == None: task_filter = Task.objects.filter(status__exact=q) elif q == None and start_date != None and end_date != None: task_filter = Task.objects.filter( Q(creation_date__date__range=[start_date, end_date]) | Q(creation_date__date__range=[end_date, start_date]) ) elif q != None and start_date != None and end_date != None: task_filter = Task.objects.filter( Q(status__exact=q, creation_date__date__range=[start_date, end_date]) | Q(status__exact=q, creation_date__date__range=[end_date, start_date]) ) else: task_filter = Task.objects.all()

can be simplified if you will collect dates and status in array and after that send to filter

At the moment I had a gap in knowledge at this point. I figured out how queryset works in django. At the moment, I understand that I can simplify and do even better, as an option, use the django-filter library, create a separate filter.py file and write classes for filtering there.

"Also i do not understand logic start_date = datetime.strptime(self.request.GET.get('startDate'), '%d.%m.%Y').date() \ if self.request.GET.get('startDate') else self.request.POST.get('startDate') basically if in get do not present date you get it from post, but do not convert to date"

I used the conversion, since the input that returns the date to me has the value "DD.MM.YYYY", django uses the date "YYYY-MM-DD" - and I got an error that the date format was not suitable and this method was found for Google solution on stackoverflow.

So I will go deeper into this issue.
