how to resolve attributes from a more complex python object

[zakerzadeh]

I have a class as below

class Class1:
def init(self):
self.id = ....
self.name = ....
self.type = List[Type()]

class Type:
def init(self):
self.model = ...
self.address = ....

my target object is an object of Class1 which has an attribute of class Type. I want to write a rule like below

"name == 'xyz' and type.model = 'abc' ", but it doesn't resolved properly. How can I achieve my goal?

Use the attribute resolver. https://zerosteiner.github.io/rule-engine/getting_started.html#attribute-backed-objects

Thanks for your prompt response. I did write a attribute resolver for my custom class, however something that I can't still figure our is how to evaluate a rule such as (type.model = 'abc' and type.address = 'xyz').

type attribute of Class1 is a List, I want to check if both model and address of one of the elements of the list satisfy my above condition. Any clue on how to do it? appreciate it.
