Thanks John,
You got me pointing in the right direction.
I reduced my admin.py to this:
from shipping.zone_shipping.models import Carrier, Zone, Tarif
from satchmo.l10n.models import Country
from django.contrib import admin
admin.site.register(Carrier)
admin.site.register(Zone)
class TarifOptions(admin.ModelAdmin):
ordering = ('min_weight', 'max_weight', 'tarif')
admin.site.register(Tarif, TarifOptions)
and modified models.Shipper.cost() to this:
def cost(self):
"""
Complex calculations can be done here as long as the return
value is a dollar figure
"""
country = self.contact.shipping_address.country.name
weight = 0
product_weight = 0
for cartitem in self.cart.cartitem_set.all():
if cartitem.product.weight:
product_weight = cartitem.product.weight
weight += product_weight * cartitem.quantity
tarif = 0
tarif =
Tarif.objects.filter(min_weight__lte=weight).filter(max_weight__gte=weight).filter(zone__country__name=country).filter(carrier__name
= self.carrier.name).values('tarif')
return tarif[0]['tarif']
Now the basic functionality is working, I just have to test it, and
l10n it and it'll be ready to share :D
