I'm trying to figure out how to chain filters for a many-to-many
relation ship that is evaluating to an empty set when it should not. I
basically have some a test with multiple dimms. I want to find a test
with both dimm "sizes" 1024 & 2048.
class TestLine(models.Model):
#...some test info
class Dimm(models.Model):
testline = models.ForeignKey(TestLine)
size = models.IntegerField()
models.TestLine.objects.filter(dimm__size=1024).filter(dimm__size=2048)
This returns an empty set, but I know there is a test with multiple
dimm objects and meets this criteria. Is there a limitation that I'm
missing here? Is there an alternative method to accomplish the intent
here?
Thanks for any help,
Kevin
