2-3: LGTM! Imports align with Django's validation framework.The imports are appropriate for integrating Django's password validation into the serializer.
36-36: Excellent! Core security fix enforces validation.Adding
raise_exception=Trueensures that validation failures are consistently caught and returned to the client, preventing weak passwords from slipping through. This directly addresses the security gap mentioned in the PR objectives.
38-52: LGTM! Clean refactoring with validated_data.The update logic correctly uses
validated_dataafter validation, maintaining the existing behavior while integrating with the new validation flow. The old password check and error response structure remain intact.care/users/tests/test_change_password.py (4)
1-16: LGTM! Well-structured test setup.The setup follows Django testing best practices with proper user creation, authentication, and URL resolution. The test user password ("StrongPass@123") is appropriately strong for testing validation scenarios.
18-28: LGTM! Comprehensive weak password validation test.This test effectively verifies that Django's password validators reject weak passwords and return the appropriate error response. The assertion on
new_passwordbeing in the error keys ensures the validation is properly attributed to the correct field.
30-38: LGTM! Proper verification of old password check.This test ensures that users must provide the correct current password to change it. The assertions correctly verify both the status code and the error field, which aligns with the expected behavior in the view.
40-51: LGTM! Thorough verification of successful password change.This test excellently verifies the complete flow, including the critical step of confirming that the password is actually persisted in the database. The use of
refresh_from_db()followed bycheck_password()ensures the change isn't just a response facade but a genuine database update.

22-31: Good work addressing the exception chaining feedback.The validation method correctly uses Django's password validators and now properly preserves the exception chain with
from e. This implementation follows Django best practices.One optional consideration: you might want to validate that the new password differs from the old password, though this is not strictly required by Django and can be deferred if not needed.
💡 Optional enhancement: reject identical passwords
def validate_new_password(self, value): """ Validate the new password against Django's password policies. """ user = self.context["request"].user + if user.check_password(value): + raise serializers.ValidationError( + "New password must be different from the current password." + ) try: validate_password(value, user=user) except DjangoValidationError as e: raise serializers.ValidationError(e.messages) from e return value

2-3: LGTM! Imports are appropriate for Django password validation.The necessary imports are in place for the new validation logic.
13-17: LGTM! Clear and informative docstring.The updated docstring accurately describes the serializer's validation behavior.
40-40: LGTM! Docstring is clear.
47-49: LGTM! Method documentation added.Nice to see the method documented, even though it might seem somewhat obvious to some.
52-64: LGTM! The update flow is well-structured.The validation enforcement with
raise_exception=Trueand the proper use ofset_password()+save()correctly implement the password change logic. The explicit old password check with clear error messaging is a nice touch.The static analysis hints about unused
argsandkwargsparameters can be safely ignored—they're standard parameters for overriding DRF'sUpdateAPIView.update()method.
