signals or triggers in SQLAlchemy

Question

does SQLAlchemy have something similar to Django's signal concept? Basically, I'd like to trigger a few functions when I pre-save or post-save some entity objects. Thanks.

Edit: I JUST want equivalent of django-signals in SQLAlchemy.

I think you are looking for `ORM Events'. You can find documentation here:
