Django: Total birthdays each day for the next 30 days

Question

I\'ve got a model similar to this:

class Person(models.Model):
    name = models.CharField(max_length=40)
    birthday = DateTimeField() # their next birthda         


        

Answer 1

(Queryset of people with a birthday in the next X days) Found cool solution for this! For me it works!

from datetime import datetime, timedelta
import operator

from django.db.models import Q

def birthdays_within(days):

    now = datetime.now()
    then = now + timedelta(days)

    # Build the list of month/day tuples.
    monthdays = [(now.month, now.day)]
    while now <= then:
        monthdays.append((now.month, now.day))
        now += timedelta(days=1)

    # Tranform each into queryset keyword args.
    monthdays = (dict(zip(("birthday__month", "birthday__day"), t)) 
                 for t in monthdays)


    # Compose the djano.db.models.Q objects together for a single query.
    query = reduce(operator.or_, (Q(**d) for d in monthdays))

    # Run the query.
    return Person.objects.filter(query)

But it get a list of persons that have a birthday in date range. You should change a bit.
