I can add it for you if you're busy and allow me to... :)

Thanks a lot! I would have tried to do something with tuples, but this seems to make easy sense.ToddOn Mar 30, 2006, at 6:06 AM, Ned Batchelder wrote: Sorry, sent the email before the formatting was right: class K:

And there's a bug! The body of choices() should be:
def choices(self):
return [(k.v, k.label) for k in self.klist]

What I've done in these cases is to define a Constants class:

def __init__(self, **kwargs):

The tutorial explains how to get objects based on field values, but I
need to get a subset of the objects in a OneToMany relationship based
on one of their values. Here's an example:
BRANCH_KINDS = ((0, 'Main'), (1, 'Auxiliary'), (2, 'Dead'),)
class Trunk(meta.Model):
