Monkey patching a @property

Question

Is it at all possible to monkey patch the value of a @property of an instance of a class that I do not control?

class Foo:
    @property
    def bar         


        

Answer 1

In case someone needs to patch a property while being able to call the original implementation, here is an example:

@property
def _cursor_args(self, __orig=mongoengine.queryset.base.BaseQuerySet._cursor_args):
    # TODO: remove this hack when we upgrade MongoEngine
    # https://github.com/MongoEngine/mongoengine/pull/2160
    cursor_args = __orig.__get__(self)
    if self._timeout:
        cursor_args.pop("no_cursor_timeout", None)
    return cursor_args


mongoengine.queryset.base.BaseQuerySet._cursor_args = _cursor_args
