Laurie Opperman <[email protected]> added the comment:
Turns out, that as a non-data descriptor, a cached property already has
setting/updating and clearing through the normal mechanisms in Python. This
feature request is therefore redundant: perhaps a new issue to document this
inherent behaviour?
Unless you explicitly want to make cached property updating not allowed, but
that's easily implemented in application code by sub-classing
`functools.cached_property` and defining `__set__` and `__delete__` to raise:
class unupdatable_cached_property(functools.cached_property):
def __set__(self, instance, value):
raise AttributeError("can't set attribute")
def __delete__(self, instance):
raise AttributeError("can't delete attribute")
