[Django]-How to filter queries with date range in django

You can use the range filter to specify a date range (inclusive):

from django.utils import timezone

today = timezone.now().date()

Product.objects.filter(added__range=[today - timezone.timedelta(days=30), today])

We first need to calculate the previous month. We can for example use relativedelta [python-doc] from the python-dateutil package [PyPi]. We can thus install this package with:

pip install python-dateutil

Then we can filter the Products such that we get all Products that were added after or one prev_month with prev_month the datetime object that is exactly one month ago:

from dateutil.relativedelta import relativedelta
from django.utils.timezone import now

def all_products(request):
    all_products = Product.objects.all()
    prev_month = now() - relativedelta(months=1)
    recently_added_products = Product.objects.filter(added__gte=prev_month)
    context = {'all_products':all_products,'recent_products':recent_products}
    return render(request,'products_list.html',context)

We thus use the __gte lookup to filter all Products with an added date greater than one month ago.

Note: if you often filter, it might be better to add a db_index=True [Django-doc] on your added field:

class Product(models.Model):
    # ...
    added = model.DateTimeField(auto_now_add=True, db_index=True)

You can use python datetime and do something like this

import datetime

recently_added_products = Product.objects.filter(date__gte=datetime.date(2019, 7, 1), date__lte=datetime.date(2019, 7, 31))
