I need to filter model with (datetime.now() < end) My model
class Quiz(models.Model) :
title = models.CharField(max_length=50)
start = models.DateTimeFieldField(default="2021-10-10")
end = models.DateTimeFieldField(default="2021-10-11")
My view
class GetQuizView(generics.ListAPIView) :
def get_queryset(self):
now = datetime.now()
return Quiz.objects.filter(start = now)
serializer_class = QuizListSerializer
But I can only filter with equal time, I can't use > or <
You would use __gt, __lt, __gte and __lte
See the docs: https://docs.djangoproject.com/en/3.2/ref/models/expressions/
You can write your queryset to look like this
class GetQuizView(generics.ListAPIView) :
def get_queryset(self):
now = datetime.now()
end = "2021-10-11"
return Quiz.objects.filter(start__range=[end, now])
serializer_class = QuizListSerializer
Note that i hardcoded the value off end date which is not a good practice, you can easily specify the range (days) of your filter using the datetime library
Here is another code snippet
import pytz
from datetime import date, timedelta
from django.conf import settings
#timezone aware object
today = datetime.today().astimezone(pytz.timezone(settings.TIME_ZONE))
one_week = timedelta(days=7)
end_date = today-one_week
class GetQuizView(generics.ListAPIView) :
def get_queryset(self):
return Quiz.objects.filter(start__range=[end_date, today])
serializer_class = QuizListSerializer
You can also use the django __lt, and __gt filter as per doc
Note: This essence of astimezone() is to make the query timezone aware, and then make the timezone inherit from your project timezone configuration as defined in your project settings.py
