Thank you for your hard work on this project! 😊 While your implementation covers most of the task requirements, there are a few critical issues that need to be addressed to ensure the code functions correctly. Specifically, the IntegerRange descriptor's __get__ and __set__ methods need to interact with the instance's dictionary to manage attribute values properly. Additionally, the can_access method should rely on the descriptors for validation rather than directly instantiating SlideLimitationValidator. Once these issues are resolved, your code will be in great shape! Keep up the great work, and don't hesitate to reach out if you need further guidance. 🚀

The __get__ method should return the value from the instance's dictionary using instance.__dict__[self.name] instead of getattr(instance, self.name). This is because descriptors are meant to manage instance attributes directly.

The __set__ method should set the value in the instance's dictionary using instance.__dict__[self.name] = value after validation. This ensures that the descriptor correctly manages the attribute value.

The can_access method should not instantiate SlideLimitationValidator directly. Instead, the Visitor attributes should be set, and the descriptors will automatically validate them. Consider removing the instantiation and relying on the descriptors for validation.

Great effort on implementing the IntegerRange descriptor and the Slide class! 🎉 However, there are a few key areas that need attention:
-
IntegerRangeDescriptor: You've done well with the__get__and__set__methods, which correctly manage attribute values using the instance's dictionary. -
SlideClass: Thecan_accessmethod should utilize thelimitation_classfor validation. Instead of directly accessing the visitor's attributes, instantiate thelimitation_classand use it to validate the attributes. This ensures that the validation logic is applied correctly. -
Error Handling: Ensure that any errors raised during validation are handled appropriately within the
can_accessmethod.
Remember, addressing these issues will enhance the functionality and robustness of your code. Keep up the good work and continue learning from these experiences! 🚀

The can_access method should rely on the IntegerRange descriptors for validation rather than directly accessing the visitor's attributes. You should attempt to set the visitor's attributes using the descriptors, which will automatically trigger the validation logic. This approach ensures that the validation constraints are respected.
