#6439 closed New feature (duplicate)

support for filter methods on date field attributes

Exact matches on date field attributes such as:


are supported. For consistency, I think all filter methods on attributes such as:

filter(datefield__month__in=[1, 2, 3])

should also be supported.

FWIW I've just encountered this today trying to use this:

class Event(models.Model):
    title = models.CharField(max_length=100)
    event_date = models.DateField()

e = Event(title='My First Event', event_date=date(2008, 08, 01))
e2 = Event(title='Second Event', event_date=date(2008, 08, 12))
# Events that happen on or before the 8th of every month: Expect to only get 'My First Event'.
# This will raise: FieldError: Join on field 'event_date' not permitted.
events = Event.objects.filter(event_date__day__lte=8)

Accepted, though I think it's a dude of another ticket. Really this is representative of a large issue about fields defining their own lookups, and chaining those. But I don't know the dupe's #, so I'll let this be open.

Fixed by #9596 in Django 1.9.filter. Sytanx is (datefield__date__month__in=[1, 2, 3])
