I implement one-to-many relationship between Order and OrderItem
models.
in the OrderController.py
@expose(template='kid:test.OrderController.templates.show')
def show(self,id, **kw):
"""Show record in model"""
record = Order.get(int(id))
orderItems = NetworkGroup.all_related_orderItems(id)
return dict(record = record, orderItems=orderItems)
in the Order class in model.py:
def all_related_orderItems(self,id):
return [orderItem for orderItem in self.orderItems
if (orderItem.groupID == id)]
but when browsing to http://localhost:8080/Orders/show/1
It throws the message that unbound method all_related_orderItems()
must be called with Order instance as first argument.
Thanks, i'm nascent in python.
