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?

Answer

Use

Sample.objects.filter(date__range=["2011-01-01", "2011-01-31"])

Or if you are just trying to filter month wise:

Sample.objects.filter(date__year='2011', 
                      date__month='01')

Edit

As Bernhard Vallant said, if you want a queryset which excludes the specified range ends you should consider his solution, which utilizes gt/lt (greater-than/less-than).
