bust() equivalent for cached_property about walrus HOT 3 CLOSED

Hmm, I don't really see how since accessing the property will access the underlying value. There's no handy way to add the bust() method if you see what I'm saying. So:

class MyObject(object):
    @cache.cached_property()
    def the_func(self):
        return 'hello'

obj = MyObject()
obj.the_func  # Accesses the cache
obj.the_func.bust()  # Not possible since the returned value is whatever was in the cache.

If you want bust you'll probably just need the regular decorator.

Appreciate the quick response. I'm quite the Python newbie, so I had to go back and better understand properties in general. Perhaps I should be asking something else.

Would it be possible to use 'deleting' the cached property and have that effectively bust() the cache.

del obj.the_func
or the equivalent...
delattr(obj, 'the_func')

Yes, del obj.the_func should actually work. Reopening, thanks for the great idea.
