Are you sure you mean "Order" not "NetworkGroup"? Because in your first example above you call the "all_related_orderItems" on the "NetworkGroup" class, not on the "Order" class. Also, if you want to call the method on a class, it must be a class, method, so that it receives the class as the first argument, not an instance (there is no instance, when calling the method on the class). But from your code I can't deduce the relationships between you model since there are several inconsistencies in the example code you post. Please paste you model.py code at http://paste.turbogears.org/ and post the link here.
