Not being a Python guru by any stretch of the imagination, I have no
idea if the following is a proper way to do it, but adding:
"
def __unicode__(self):
return u'MAC Address'
"
to the MacAddressField class definition does work. For my purposes. As
long as I'm o.k. with the label always being 'MAC Address' no matter
where I use it.
It would be nice to figure out the preferred way of implementing
custom fields. The documentation, while nice, seems to be incomplete
in this area... Google hasn't been very helpful in searching for
examples either.
Anybody out there know of one or more good examples of implementing
and using these beasts?
