#21175 closed Bug (wontfix)

abstract base model classes never fire class_prepared signal

Description

I can't think of a reason why this would be the preferred behavior.

In fact, ensure_default_managers (which is one of two uses of class_prepared in Django itself) is written with a specific case to handle abstract classes, even though it will never receive one, so clearly somebody else had an expectation that they would fire the signal too.

I am closing this; in light of #24313 and discussion on #24215, I no longer think it makes sense for abstract models to fire class_prepared. (In fact I'm hopeful that we can get rid of class_prepared altogether, making it moot.)
