no-member for Generic class with new astroid 2.15.7 #9069
Description
Bug description
I get a `no-member` error for attributes of a generic dataclass when running with the new astroid 2.15.7. This is true for both pylint 2.17.5 and the new pylint 2.17.6. $ cat p.py # pylint: disable=missing-module-docstring invalid-name missing-class-docstring from dataclasses import dataclass from typing import Generic, TypeVar T_Inner = TypeVar("T_Inner", bound="Inner") @dataclass class Inner: inner_attribute: str @dataclass class Outer(Generic[T_Inner]): inner: T_Inner x = Outer(inner=Inner(inner_attribute="magic xylophone")) print(x.inner.inner_attribute)Configuration
