How do I filter query objects by date range in Django?

I've got a field in one model like:

class Sample(models.Model):
    date = fields.DateField(auto_now=False)

Now, I need to filter the objects by a date range.

How do I filter all the objects that have a date between 1-Jan-2011 and 31-Jan-2011?

python django django-models django-queryset date-range

When doing django ranges with a filter make sure you know the difference between using a date object vs a datetime object. __range is inclusive on dates but if you use a datetime object for the end date it will not include the entries for that day if the time is not set.

from datetime import date, timedelta

startdate = date.today()
enddate = startdate + timedelta(days=6)
Sample.objects.filter(date__range=[startdate, enddate])

returns all entries from startdate to enddate including entries on those dates. Bad example since this is returning entries a week into the future, but you get the drift.

from datetime import datetime, timedelta

startdate = datetime.today()
enddate = startdate + timedelta(days=6)
Sample.objects.filter(date__range=[startdate, enddate])

will be missing 24 hours worth of entries depending on what the time for the date fields is set to.
