I am facing an issue in crud_service update function in YDK, where it fails to fetch the instance of a nested class. I have fixed this issue. What are the next steps?

Hi,

The update operation in crud_service.py has a _create_update_entity_filter function, which tries to read the entity in the module, the

update_filter = getattr(module, entity._meta_info().name)() fails to fetch the nested class instance(for example Interfaces.Interface() is not accessible) because of the behavior of python getattr function, which does not support consecutive attribute retrievals.

The fix for this issue can be to use the operator.attrgetattr() python function instead.

import operator

update_filter = operator.attrgetter(entity._meta_info().name)(module)()

Please look into this issue and provide a fix.

Thanks,

Hemalathaa
