Sorry, it's Order as the correct model. btw, i think i have described my question clearly, just asking for help for any example of displaying all related "child" models on the "show" form of "parent" model.
in my scenario, likewise, on http://localhost:8080/orders/show/1, i hope to display all of orderitems belonging to Order 1. pls forgive me, i'm novice on Python as well as Turbogears, i can't find any full example of one-to-many relation over Google, including how to display them together on "parent model"'s showing form Thanks anyway On Oct 21, 12:50 pm, Christopher Arndt <[EMAIL PROTECTED]> wrote: > PigletWatcher schrieb: > > > > > > > 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 tohttp://localhost:8080/Orders/show/1 > > > It throws the message that unbound method all_related_orderItems() > > must be called with Order instance as first argument. > > Are you sure you mean "Order" not "NetworkGroup"?
