Description

To retrieve a deferred model attributes, the __get__ method is called twice. This is because it uses the getattr() function, which in turn causes the __get__ method to be called again.

To prevent this unnecessary call, we can simply delete it (since at that moment the instance dict already contains the reloaded value). This reduces the number of method calls.
