It occures _sometimes_... Not always :/.
views.py:
def checkout_authenticated(request):
log.info("checkout_authenticated(request)")
try:
order = get_order(request)
user = request.user
if request.method == 'POST':
form = OrderCheckoutForm(request.POST, instance = order)
if form.is_valid():
form.save()
log.debug('Cash on delivery: %s',
order.shipping.cash_on_delivery)
if order.shipping.cash_on_delivery:
log.info("NOW PICKLINGERROR")
return HttpResponseRedirect('/accounts/
cash_on_delivery')#cash_on_delivery(request)
...
forms.py:
class OrderCheckoutForm(forms.ModelForm):
class Meta:
model = Order
exclude = ('status',
'user')
models.py:
class Shipping(models.Model):
name = models.CharField(max_length = 256)
price = models.DecimalField(max_digits = 10, decimal_places = 2)
description = models.TextField(blank = True, null = True)
cash_on_delivery = models.BooleanField(default = False)
class Order(models.Model):
date = models.DateField(editable = False, auto_now_add=True)
status = models.CharField(max_length = 1, choices = STATUS,
default = Status.NEW)
shipping = models.ForeignKey(Shipping, related_name = 'orders',
null = True)
address = models.ForeignKey(Address, related_name =
'address_order', null = True)
invoice = models.BooleanField(default = False)
company = models.ForeignKey(Company, related_name =
'company_order', blank = True, null = True)
I think the reason is:
price = models.DecimalField(max_digits = 10, decimal_places = 2)
Thanks in advance,
Etam.
