Review Comment:
   The various SQLAlchemy hooks, `after_insert`, `after_delete`, etc. pass in 
the connection from which we instantiate a new session which was never closed. 
I'm really not sure what's wrong with simply using the Flask-SQLAlchemy 
session, i.e., `db.session`.

Review Comment:
   This session was never closed, though it's unclear why a new session was 
created.
