Hi Rick
I really need help with the validation. Even with the two separate
zones, either country can still choose another zone's pricing. Not
sure how to proceed, and I've never written a valid zone checker
before, but what appears to be there already seems inadequate:
def valid(self, order=None):
"""
Check if shipping is valid for country and set zone
accordingly. Fallback
to default zone if set
"""
assert(self._calculated)
# I think its reasonable to assume this shipping method should
# not be used on an order that doesn't weigh anything.
if not self._price or self._price == Decimal('0.0'):
return False
if self._zone and self._cost:
return True
There should be a check here to see if the selected country belongs to
the zone, and if it doesn't it should check the next zone, right?
