Hi all,
in one of my models I have
class Watchfolder(models.Model):
formats = models.ManyToManyField(Format)
destination = models.ManyToManyField(
Destination,
related_name="WFDestinations",
limit_choices_to={'metadata_destination':False},
blank=True,
validator_list=[destination_validator])
destination_metadata = models.ManyToManyField(
Destination,
related_name="WFMetadataDestinations",
limit_choices_to={'metadata_destination':True},
blank=True,
validator_list=[md_destination_validator])
When I try to get at these managers I get:
>>> w.formats.all()
Traceback (most recent call last):

I know I can workaround this problem by going at it from behind so to speak, that is
for format in Format.objects.all():
for wf in format.watchfolder_set.all
():
if wf == my_watchfolder:
but somehow that doesn't satisfy me. Am I doing anything wrong or is there just something broken?
